• How should I plan the inheritance structure for my game?

  - by Eric Thoma

  I am trying to write a platform shooter in C++ with a really good class structure for robustness. The game itself is secondary; it is the learning process of writing it that is primary. I am implementing an inheritance tree for all of the objects in my game, but I find myself unsure on some decisions. One specific issue that it bugging me is this: I have an Actor that is simply defined as anything in the game world. Under Actor is Character. Both of these classes are abstract. Under Character is the Philosopher, who is the main character that the user commands. Also under Character is NPC, which uses an AI module with stock routines for friendly, enemy and (maybe) neutral alignments. So under NPC I want to have three subclasses: FriendlyNPC, EnemyNPC and NeutralNPC. These classes are not abstract, and will often be subclassed in order to make different types of NPC's, like Engineer, Scientist and the most evil Programmer. Still, if I want to implement a generic NPC named Kevin, it would nice to be able to put him in without making a new class for him. I could just instantiate a FriendlyNPC and pass some values for the AI machine and for the dialogue; that would be ideal. But what if Kevin is the one benevolent Programmer in the whole world? Now we must make a class for him (but what should it be called?). Now we have a character that should inherit from Programmer (as Kevin has all the same abilities but just uses the friendly AI functions) but also should inherit from FriendlyNPC. Programmer and FriendlyNPC branched away from each other on the inheritance tree, so inheriting from both of them would have conflicts, because some of the same functions have been implemented in different ways on the two of them. 1) Is there a better way to order these classes to avoid these conflicts? Having three subclasses; Friendly, Enemy and Neutral; from each type of NPC; Engineer, Scientist, and Programmer; would amount to a huge number of classes. I would share specific implementation details, but I am writing the game slowly, piece by piece, and so I haven't implemented past Character yet. 2) Is there a place where I can learn these programming paradigms? I am already trying to take advantage of some good design patterns, like MVC architecture and Mediator objects. The whole point of this project is to write something in good style. It is difficult to tell what should become a subclass and what should become a state (i.e. Friendly boolean v. Friendly class). Having many states slows down code with if statements and makes classes long and unwieldy. On the other hand, having a class for everything isn't practical. 3) Are there good rules of thumb or resources to learn more about this? 4) Finally, where does templating come in to this? How should I coordinate templates into my class structure? I have never actually taken advantage of templating honestly, but I hear that it increases modularity, which means good code.

• How to safely copy an object?

  - by Prog

  This question is going to be a little long. Please bear with me. Something that happened in a project of mine made me think about how to safely copy objects. I'll present the situation I had and then ask a question. There was a class SomeClass: class SomeClass{ Thing[] things; public SomeClass(Thing[] things){ this.things = things; } // irrelevant stuff omitted public SomeClass copy(){ return new SomeClass(things); } } There was another class Processor that takes SomeClass objects, copies them (via someClassInstance.copy()), manipulates the copy's state, and returns the copy. Here it is: class Processor{ public SomeClass processObject(SomeClass object){ SomeClass copy = object.copy(); manipulateTheCopy(copy); return copy; } // irrelevant stuff omitted } I ran this, and it had bugs. I looked into these bugs, and it turned out that the manipulations Processor does on copy actually affect not only the copy, but also the original SomeClass object that was passed into processObject. I found out that it was because the original and the copy shared state - because the original passed it's field things into the copy when creating it. This made me realize that copying objects is harder than simply instantiating them with the same fields as the original. For the two objects to be completely disconnected, without any shared state, each of the fields passed to the copy also has to be copied. And if that object contains other objects - they have to be copied too. And so on. So basically, in order to be able to actually copy an object, each class in the system must have a copy() method, that also invokes copy() on all of it's fields, and so on. So for example, for copy() in SomeClass to work, it needs to look like this: public SomeClass copy(){ Thing[] copyThings = new Thing[things.length]; for(int i=0; i<things.length; i++) copyThings[i] = things[i].copy(); return new SomeClass(copyThings); } And if Thing has object fields of it's own, than it's own copy() method must be appropriate: class Thing{ Apple apple; Pencil pencil; int number; public Thing(Apple apple, Pencil pencil, int number){ this.apple = apple; this.pencil = pencil; this.number = number; } public Thing copy(){ // 'number' is a primitve. return new Thing(apple.getCopy(), pencil.getCopy(), number); } } And so on. Of course, instead of all classes having a copy() method, the copying mechanism can happen in all of the getters and the constructors of classes (unless places where it isn't suitable, for example when the field points to an external object, not to an object that 'is part' of this object). Still, that means that in order to be able to safely copy an object - most classes would have to have copying mechanisms in their getters. My question is divided into two parts: How frequently do you need to get a copy of an object? Is this a regular issue? Is the technique described common and/or reasonable? Or is there a better way to make safe copies of objects? Or is there an easier way to safely copy objects, without them sharing any state?

• Investigating Strategies For Functional Decomposition

  - by Liam McLennan

  Introducing Functional Decomposition Before I begin I must apologise. I think I am using the term ‘functional decomposition’ loosely, and probably incorrectly. For the purpose of this article I use functional decomposition to mean the recursive splitting of a large problem into increasingly smaller ones, so that the one large problem may be solved by solving a set of smaller problems. The justification for functional decomposition is that the decomposed problem is more easily solved. As software developers we recognise that the smaller pieces are more easily tested, since they do less and are more cohesive. Functional decomposition is important to all scientific pursuits. Once we understand natural selection we can start to look for humanities ancestral species, once we understand the big bang we can trace our expanding universe back to its origin. Isaac Newton acknowledged the compositional nature of his scientific achievements: If I have seen further than others, it is by standing upon the shoulders of giants   The Two Strategies For Functional Decomposition of Computer Programs Private Methods When I was working on my undergraduate degree I was taught to functionally decompose problems by using private methods. Consider the problem of painting a house. The obvious solution is to solve the problem as a single unit: public void PaintAHouse() { // all the things required to paint a house ... } We decompose the problem by breaking it into parts: public void PaintAHouse() { PaintUndercoat(); PaintTopcoat(); } private void PaintUndercoat() { // everything required to paint the undercoat } private void PaintTopcoat() { // everything required to paint the topcoat } The problem can be recursively decomposed until a sufficiently granular level of detail is reached: public void PaintAHouse() { PaintUndercoat(); PaintTopcoat(); } private void PaintUndercoat() { prepareSurface(); fetchUndercoat(); paintUndercoat(); } private void PaintTopcoat() { fetchPaint(); paintTopcoat(); } According to Wikipedia, at least one computer programmer has referred to this process as “the art of subroutining”. The practical issues that I have encountered when using private methods for decomposition are: To preserve the top level API all of the steps must be private. This means that they can’t easily be tested. The private methods often have little cohesion except that they form part of the same solution. Decomposing to Classes The alternative is to decompose large problems into multiple classes, effectively using a class instead of each private method. The API delegates to related classes, so the API is not polluted by the sub-steps of the problem, and the steps can be easily tested because they are each in their own highly cohesive class. Additionally, I think that this technique facilitates better adherence to the Single Responsibility Principle, since each class can be decomposed until it has precisely one responsibility. Revisiting my previous example using class composition: public class HousePainter { private undercoatPainter = new UndercoatPainter(); private topcoatPainter = new TopcoatPainter(); public void PaintAHouse() { undercoatPainter.Paint(); topcoatPainter.Paint(); } } Summary When decomposing a problem there is more than one way to represent the sub-problems. Using private methods keeps the logic in one place and prevents a proliferation of classes (thereby following the four rules of simple design) but the class decomposition is more easily testable and more compatible with the Single Responsibility Principle.

• Patterns for a tree of persistent data with multiple storage options?

  - by Robin Winslow

  I have a real-world problem which I'll try to abstract into an illustrative example. So imagine I have data objects in a tree, where parent objects can access children, and children can access parents: // Interfaces interface IParent<TChild> { List<TChild> Children; } interface IChild<TParent> { TParent Parent; } // Classes class Top : IParent<Middle> {} class Middle : IParent<Bottom>, IChild<Top> {} class Bottom : IChild<Middle> {} // Usage var top = new Top(); var middles = top.Children; // List<Middle> foreach (var middle in middles) { var bottoms = middle.Children; // List<Bottom> foreach (var bottom in bottoms) { var middle = bottom.Parent; // Access the parent var top = middle.Parent; // Access the grandparent } } All three data objects have properties that are persisted in two data stores (e.g. a database and a web service), and they need to reflect and synchronise with the stores. Some objects only request from the web service, some only write to it. Data Mapper My favourite pattern for data access is Data Mapper, because it completely separates the data objects themselves from the communication with the data store: class TopMapper { public Top FetchById(int id) { var top = new Top(DataStore.TopDataById(id)); top.Children = MiddleMapper.FetchForTop(Top); return Top; } } class MiddleMapper { public Middle FetchById(int id) { var middle = new Middle(DataStore.MiddleDataById(id)); middle.Parent = TopMapper.FetchForMiddle(middle); middle.Children = BottomMapper.FetchForMiddle(bottom); return middle; } } This way I can have one mapper per data store, and build the object from the mapper I want, and then save it back using the mapper I want. There is a circular reference here, but I guess that's not a problem because most languages can just store memory references to the objects, so there won't actually be infinite data. The problem with this is that every time I want to construct a new Top, Middle or Bottom, it needs to build the entire object tree within that object's Parent or Children property, with all the data store requests and memory usage that that entails. And in real life my tree is much bigger than the one represented here, so that's a problem. Requests in the object In this the objects request their Parents and Children themselves: class Middle { private List<Bottom> _children = null; // cache public List<Bottom> Children { get { _children = _children ?? BottomMapper.FetchForMiddle(this); return _children; } set { BottomMapper.UpdateForMiddle(this, value); _children = value; } } } I think this is an example of the repository pattern. Is that correct? This solution seems neat - the data only gets requested from the data store when you need it, and thereafter it's stored in the object if you want to request it again, avoiding a further request. However, I have two different data sources. There's a database, but there's also a web service, and I need to be able to create an object from the web service and save it back to the database and then request it again from the database and update the web service. This also makes me uneasy because the data objects themselves are no longer ignorant of the data source. We've introduced a new dependency, not to mention a circular dependency, making it harder to test. And the objects now mask their communication with the database. Other solutions Are there any other solutions which could take care of the multiple stores problem but also mean that I don't need to build / request all the data every time?

• Generic Adjacency List Graph implementation

  - by DmainEvent

  I am trying to come up with a decent Adjacency List graph implementation so I can start tooling around with all kinds of graph problems and algorithms like traveling salesman and other problems... But I can't seem to come up with a decent implementation. This is probably because I am trying to dust the cobwebs off my data structures class. But what I have so far... and this is implemented in Java... is basically an edgeNode class that has a generic type and a weight-in the event the graph is indeed weighted. public class edgeNode<E> { private E y; private int weight; //... getters and setters as well as constructors... } I have a graph class that has a list of edges a value for the number of Vertices and and an int value for edges as well as a boolean value for whether or not it is directed. The brings up my first question, if the graph is indeed directed, shouldn't I have a value in my edgeNode class? Or would I just need to add another vertices to my LinkedList? That would imply that a directed graph is 2X as big as an undirected graph wouldn't it? public class graph { private List<edgeNode<?>> edges; private int nVertices; private int nEdges; private boolean directed; //... getters and setters as well as constructors... } Finally does anybody have a standard way of initializing there graph? I was thinking of reading in a pipe-delimited file but that is so 1997. public graph GenereateGraph(boolean directed, String file){ List<edgeNode<?>> edges; graph g; try{ int count = 0; String line; FileReader input = new FileReader("C:\\Users\\derekww\\Documents\\JavaEE Projects\\graphFile"); BufferedReader bufRead = new BufferedReader(input); line = bufRead.readLine(); count++; edges = new ArrayList<edgeNode<?>>(); while(line != null){ line = bufRead.readLine(); Object edgeInfo = line.split("|")[0]; int weight = Integer.parseInt(line.split("|")[1]); edgeNode<String> e = new edgeNode<String>((String) edges.add(e); } return g; } catch(Exception e){ return null; } } I guess when I am adding edges if boolean is true I would be adding a second edge. So far, this all depends on the file I write. So if I wrote a file with the following Vertices and weights... Buffalo | 18 br Pittsburgh | 20 br New York | 15 br D.C | 45 br I would obviously load them into my list of edges, but how can I represent one vertices connected to the other... so on... I would need the opposite vertices? Say I was representing Highways connected to each city weighted and un-directed (each edge is bi-directional with weights in some fictional distance unit)... Would my implementation be the best way to do that? I found this tutorial online Graph Tutorial that has a connector object. This appears to me be a collection of vertices pointing to each other. So you would have A and B each with there weights and so on, and you would add this to a list and this list of connectors to your graph... That strikes me as somewhat cumbersome and a little dismissive of the adjacency list concept? Am I wrong and that is a novel solution? This is all inspired by steve skiena's Algorithm Design Manual. Which I have to say is pretty good so far. Thanks for any help you can provide.

• Executing Stored Procedures in Visual Studio LightSwitch.

  - by dataintegration

  A LightSwitch Project is very easy way to visualize and manipulate information directly from one of our ADO.NET Providers. But when it comes to executing the Stored Procedures, it can be a bit more complicated. In this article, we will demonstrate how to execute a Stored Procedure in LightSwitch. For the purposes of this article, we will be using the RSSBus Email Data Provider, but the same process will work with any of our ADO.NET Providers. Creating the RIA Service. Step 1: Open Visual Studio and create a new WCF RIA Service Class Project. Step 2:Add the reference to the RSSBus Email Data Provider dll in the (ProjectName).Web project. Step 3: Add a new Domain Service Class to the (ProjectName).Web project. Step 4: In the new Domain Service Class, create a new class with the attributes needed for the Stored Procedure's parameters. In this demo, the Stored Procedure we are executing is called SendMessage. The parameters we will need are as follows: public class NewMessage{ [Key] public int ID { get; set; } public string FromEmail { get; set; } public string ToEmail { get; set; } public string Subject { get; set; } public string Text { get; set; } } Note: The created class must have an ID which will serve as the key value. Step 5: Create a new method that will executed when the insert event fires. Inside this method you can use the standards ADO.NET code which will execute the stored procedure. [Insert] public void SendMessage(NewMessage newMessage) { try { EmailConnection conn = new EmailConnection(connectionString); EmailCommand comm = new EmailCommand("SendMessage", conn); comm.CommandType = System.Data.CommandType.StoredProcedure; if (!newMessage.FromEmail.Equals("")) comm.Parameters.Add(new EmailParameter("@From", newMessage.FromEmail)); if (!newMessage.ToEmail.Equals("")) comm.Parameters.Add(new EmailParameter("@To", newMessage.ToEmail)); if (!newMessage.Subject.Equals("")) comm.Parameters.Add(new EmailParameter("@Subject", newMessage.Subject)); if (!newMessage.Text.Equals("")) comm.Parameters.Add(new EmailParameter("@Text", newMessage.Text)); comm.ExecuteNonQuery(); } catch (Exception exc) { Console.WriteLine(exc.Message); } } Step 6: Create a query method. We are not going to be using getNewMessages(), so it does not matter what it returns for the purpose of our example, but you will need to create a method for the query event as well. [Query(IsDefault=true)] public IEnumerable<NewMessage> getNewMessages() { return null; } Step 7: Rebuild the whole solution. Creating the LightSwitch Project. Step 8: Open Visual Studio and create a new LightSwitch Application Project. Step 9: On the Data Sources, add a new data source. Choose a WCF RIA Service Step 10: Choose to add a new reference and select the (Project Name).Web.dll generated from the RIA Service. Step 11: Select the entities you would like to import. In this case, we are using the recently created NewMessage entity. Step 13: On the Screens section, create a new screen and select the NewMessage entity as the Screen Data. Step 14: After you run the project, you will be able to add a new record and save it. This will execute the Stored Procedure and send the new message. If you create a screen to check the sent messages, you can refresh this screen to see the mail you sent. Sample Project To help you with get started using stored procedures in LightSwitch, download the fully functional sample project. You will also need the RSSBus Email Data Provider to make the connection. You can download a free trial here.

• Too complex/too many objects?

  - by Mike Fairhurst

  I know that this will be a difficult question to answer without context, but hopefully there are at least some good guidelines to share on this. The questions are at the bottom if you want to skip the details. Most are about OOP in general. Begin context. I am a jr dev on a PHP application, and in general the devs I work with consider themselves to use many more OO concepts than most PHP devs. Still, in my research on clean code I have read about so many ways of using OO features to make code flexible, powerful, expressive, testable, etc. that is just plain not in use here. The current strongly OO API that I've proposed is being called too complex, even though it is trivial to implement. The problem I'm solving is that our permission checks are done via a message object (my API, they wanted to use arrays of constants) and the message object does not hold the validation object accountable for checking all provided data. Metaphorically, if your perm containing 'allowable' and 'rare but disallowed' is sent into a validator, the validator may not know to look for 'rare but disallowed', but approve 'allowable', which will actually approve the whole perm check. We have like 11 validators, too many to easily track at such minute detail. So I proposed an AtomicPermission class. To fix the previous example, the perm would instead contain two atomic permissions, one wrapping 'allowable' and the other wrapping 'rare but disallowed'. Where previously the validator would say 'the check is OK because it contains allowable,' now it would instead say '"allowable" is ok', at which point the check ends...and the check fails, because 'rare but disallowed' was not specifically okay-ed. The implementation is just 4 trivial objects, and rewriting a 10 line function into a 15 line function. abstract class PermissionAtom { public function allow(); // maybe deny() as well public function wasAllowed(); } class PermissionField extends PermissionAtom { public function getName(); public function getValue(); } class PermissionIdentifier extends PermissionAtom { public function getIdentifier(); } class PermissionAction extends PermissionAtom { public function getType(); } They say that this is 'not going to get us anything important' and it is 'too complex' and 'will be difficult for new developers to pick up.' I respectfully disagree, and there I end my context to begin the broader questions. So the question is about my OOP, are there any guidelines I should know: is this too complicated/too much OOP? Not that I expect to get more than 'it depends, I'd have to see if...' when is OO abstraction too much? when is OO abstraction too little? how can I determine when I am overthinking a problem vs fixing one? how can I determine when I am adding bad code to a bad project? how can I pitch these APIs? I feel the other devs would just rather say 'its too complicated' than ask 'can you explain it?' whenever I suggest a new class.

• KnpLabs / DoctrineBehaviors Translatable - currentLocale = null

  - by Ruben

  Using the trait \Knp\DoctrineBehaviors\Model\Translatable\Translation inside an Entity, I see that the property currentLocale is never setted , so we always obtain the default locale ('en') in all the calls to $this->translate(). If I change this getDefaultLocale, all the translations are made correctly, so I think that is no problem with the fallback. I tried debug the currentLocaleCallable. I see that if I put a "var_dump ($this-container-get('request'));" in the contructor of currentLocaleCallable, the request have a locale to null. And outside the request has the correct locale.It seems that container is not in the scope: request , i don't know how can I get it to work I post an issue in github https://github.com/KnpLabs/DoctrineBehaviors/issues/71 EDITED This service is defined in vendor/knplabs/doctrine-behaviors/config/orm-services.yml and is: knp.doctrine_behaviors.reflection.class_analyzer: class: "%knp.doctrine_behaviors.reflection.class_analyzer.class%" public: false knp.doctrine_behaviors.translatable_listener: class: "%knp.doctrine_behaviors.translatable_listener.class%" public: false arguments: - "@knp.doctrine_behaviors.reflection.class_analyzer" - "%knp.doctrine_behaviors.reflection.is_recursive%" - "@knp.doctrine_behaviors.translatable_listener.current_locale_callable" tags: - { name: doctrine.event_subscriber } knp.doctrine_behaviors.translatable_listener.current_locale_callable: class: "%knp.doctrine_behaviors.translatable_listener.current_locale_callable.class%" arguments: - "@service_container" # lazy request resolution public: false EDIT 2: My composer.json "php": ">=5.3.3", "symfony/symfony": "2.3.*", "doctrine/orm": ">=2.2.3,<2.4-dev", "doctrine/doctrine-bundle": "1.2.*", "twig/extensions": "1.0.*", "symfony/assetic-bundle": "2.3.*", "symfony/swiftmailer-bundle": "2.3.*", "symfony/monolog-bundle": "2.3.*", "sensio/distribution-bundle": "2.3.*", "sensio/framework-extra-bundle": "2.3.*", "sensio/generator-bundle": "2.3.*", "incenteev/composer-parameter-handler": "~2.0", "friendsofsymfony/user-bundle": "1.3.*", "avalanche123/imagine-bundle": "v2.1", "raulfraile/ladybug-bundle": "~1.0", "genemu/form-bundle": "2.2.*", "friendsofsymfony/rest-bundle": "0.12.0", "stof/doctrine-extensions-bundle": "dev-master", "sonata-project/admin-bundle": "dev-master", "a2lix/translation-form-bundle": "1.*@dev", "sonata-project/user-bundle": "dev-master", "psliwa/pdf-bundle": "dev-master", "jms/serializer-bundle": "dev-master", "jms/di-extra-bundle": "dev-master", "knplabs/doctrine-behaviors": "dev-master", "sonata-project/doctrine-orm-admin-bundle": "dev-master", "knplabs/knp-paginator-bundle": "dev-master", "friendsofsymfony/jsrouting-bundle": "~1.1", "zendframework/zend-validator": ">=2.0.0-rc2", "zendframework/zend-barcode": ">=2.0.0-rc2"

  Trying to deploy a JSF 2 app with Spring 3.1 + JPA 2 (Hibernte 3.6.8) into JBoss 7.1.1 AS. The app was working fine on tomcat 7. Now, I have already added and changed some configurations.

• Help getting frame rate (fps) up in Python + Pygame

  - by Jordan Magnuson

  I am working on a little card-swapping world-travel game that I sort of envision as a cross between Bejeweled and the 10 Days geography board games. So far the coding has been going okay, but the frame rate is pretty bad... currently I'm getting low 20's on my Core 2 Duo. This is a problem since I'm creating the game for Intel's March developer competition, which is squarely aimed at netbooks packing underpowered Atom processors. Here's a screen from the game: ![www.necessarygames.com/my_games/betraveled/betraveled-fps.png][1] I am very new to Python and Pygame (this is the first thing I've used them for), and am sadly lacking in formal CS training... which is to say that I think there are probably A LOT of bad practices going on in my code, and A LOT that could be optimized. If some of you older Python hands wouldn't mind taking a look at my code and seeing if you can't find any obvious areas for optimization, I would be extremely grateful. You can download the full source code here: http://www.necessarygames.com/my_games/betraveled/betraveled_src0328.zip Compiled exe here: www.necessarygames.com/my_games/betraveled/betraveled_src0328.zip One thing I am concerned about is my event manager, which I feel may have some performance wholes in it, and another thing is my rendering... I'm pretty much just blitting everything to the screen all the time (see the render routines in my game_components.py below); I recently found out that you should only update the areas of the screen that have changed, but I'm still foggy on how that accomplished exactly... could this be a huge performance issue? Any thoughts are much appreciated! As usual, I'm happy to "tip" you for your time and energy via PayPal.

• CSS overflow: hidden; does not work

  - by kapil.israni

  Hi - I am having issues with overflow: hidden not working in my case. I have a div id=ticker which basically works like a scrolling ticker. something like this - http://www.tinymassive.com/ (whats happening section). So i am prepending dynamic content to div id=ticker The div id=ticker is contained in another div which is contained in another div, basically think of it like 4-5 level tree like structure body - div[id=wrapper] - div[class=main] - div[class=content] - div[class=frame] - div[class=bg] - div[class=primary-content] - div[id=ticker] Heres the css... #wrapper { width: 942px; margin: 0 auto; position:relative; overflow:hidden; } .main{ width:942px; margin:163px 0 0; overflow:hidden; } .content{ background:url(../images/content-bg.gif) repeat-y; overflow:hidden; width:662px; float:left; } .frame{ background:url(../images/frame-bg.gif) no-repeat 0 0; width:662px; } .bg{ background:url(../images/bg-bg.gif) no-repeat 0 100%; width:662px; overflow:hidden; } .primary-content{ padding: 12px 20px 40px 22px; width:620px; overflow:hidden; } #ticker { overflow: hidden; } Also if it helps - the ticker div contains a list of div[class=breadcrumps], which i am trying to scroll .breadcrumbs{ border-bottom:1px solid #ebebeb; padding:6px 0 6px 0; overflow:hidden; clear:both; } What i see is - when i prepend breadcrumps div to ticker, the page/ticker list keeps getting bigger :( Any help would be appreciated. Thanks.

• Partial template specialization of free functions - best practices

  - by Poita_

  As most C++ programmers should know, partial template specialization of free functions is disallowed. For example, the following is illegal C++: template <class T, int N> T mul(const T& x) { return x * N; } template <class T> T mul<T, 0>(const T& x) { return T(0); } // error: function template partial specialization ‘mul<T, 0>’ is not allowed However, partial template specialization of classes/structs is allowed, and can be exploited to mimic the functionality of partial template specialization of free functions. For example, the target objective in the last example can be achieved by using: template <class T, int N> struct mul_impl { static T fun(const T& x) { return x * N; } }; template <class T> struct mul_impl<T, 0> { static T fun(const T& x) { return T(0); } }; template <class T, int N> T mul(const T& x) { return mul_impl<T, N>::fun(x); } It's more bulky and less concise, but it gets the job done -- and as far as users of mul are concerned, they get the desired partial specialization. My questions is: when writing templated free functions (that are intended to be used by others), should you automatically delegate the implementation to a static method function of a class, so that users of your library may implement partial specializations at will, or do you just write the templated function the normal way, and live with the fact that people won't be able to specialize them?

• Why is jQuery so widely adopted versus other Javascript frameworks?

  - by Andrew Moore

  I manage a group of programmers. I do value my employees opinion but lately we've been divided as to which framework to use on web projects. I personally favor MooTools, but some of my team seems to want to migrate to jQuery because it is more widely adopted. That by itself is not enough for me to allow a migration. I have used both jQuery and MooTools. This particular essay tends to reflect how I feel about both frameworks. jQuery is great for DOM Manipulation, but seem to be limited to helping you do that. Feature wise, both jQuery and MooTools allow for easy DOM Selection and Manipulation: // jQuery $('#someContainer div[class~=dialog]') .css('border', '2px solid red') .addClass('critical'); // MooTools $('#someContainer div[class~=dialog]') .setStyle('border', '2px solid red') .addClass('critical'); Both jQuery and MooTools allow for easy AJAX: // jQuery $('#someContainer div[class~=dialog]') .load('/DialogContent.html'); // MooTools (Using shorthand notation, you can also use Request.HTML) $('#someContainer div[class~=dialog]') .load('/DialogContent.html'); Both jQuery and MooTools allow for easy DOM Animation: // jQuery $('#someContainer div[class~=dialog]') .animate({opacity: 1}, 500); // MooTools (Using shorthand notation, you can also use Fx.Tween). $('#someContainer div[class~=dialog]') .set('tween', {duration: 500}) .tween('opacity', 1); jQuery offers the following extras: Large community of supporters Plugin Repository Integration with Microsoft's ASP.NET and VisualStudio Used by Microsoft, Google and others MooTools offers the following extras: Object Oriented Framework with Classic OOP emulation for JS Extended native objects Higher consistency between browsers for native functions support. More easy code reuse Used by The World Wide Web Consortium, Palm and others. Given that, it seems that MooTools does everything jQuery does and more (some things I cannot do in jQuery and I can in MooTools) but jQuery has a smaller learning curve. So the question is, why did you or your team choose jQuery over another JavaScript framework? Note: While I know and admit jQuery is a great framework, there are other options around and I'm trying to take a decision as to why jQuery should be our choice versus what we use right now (MooTools)?

• django crispy-forms inline forms

  - by abolotnov

  I'm trying to adopt crispy-forms and bootstrap and use as much of their functionality as possible instead of inventing something over and over again. Is there a way to have inline forms functionality with crispy-forms/bootstrap like django-admin forms have? Here is an example: class NewProjectForm(forms.Form): name = forms.CharField(required=True, label=_(u'???????? ???????'), widget=forms.TextInput(attrs={'class':'input-block-level'})) group = forms.ModelChoiceField(required=False, queryset=Group.objects.all(), label=_(u'?????? ????????'), widget=forms.Select(attrs={'class':'input-block-level'})) description = forms.CharField(required=False, label=_(u'???????? ???????'), widget=forms.Textarea(attrs={'class':'input-block-level'})) class Meta: model = Project fields = ('name','description','group') def __init__(self, *args, **kwargs): self.helper = FormHelper() self.helper.form_class = 'horizontal-form' self.helper.form_action = 'submit_new_project' self.helper.layout = Layout( Field('name', css_class='input-block-level'), Field('group', css_class='input-block-level'), Field('description',css_class='input-block-level'), ) self.helper.add_input(Submit('submit',_(u'??????? ??????'))) self.helper.add_input(Submit('cancel',_(u'? ?????????'))) super(NewProjectForm, self).__init__(*args, **kwargs) it will display a decent form: How do I go about adding a form that basically represents this model: class Link(models.Model): name = models.CharField(max_length=255, blank=False, null=False, verbose_name=_(u'????????')) url = models.URLField(blank=False, null=False, verbose_name=_(u'??????')) project = models.ForeignKey('Project') So there will be a project and name/url links and way to add many, like same thing is done in django-admin where you are able to add extra 'rows' with data related to your main model. On the sreenshot below you are able to fill out data for 'Question' object and below that you are able to add data for QuestionOption objects -you are able to click the '+' icon to add as many QuestionOptions as you want. I'm not looking for a way to get the forms auto-generated from models (that's nice but not the most important) - is there a way to construct a form that will let you add 'rows' of data like django-admin does?

• ASP.net DAL DatasSet and Table Adapter not in namespace - Northwind Tutorial

  - by Alan

  I've been attempting to walk through the "Creating a Data Access Layer" tutorial found http://www.asp.net/learn/data-access/tutorial-01-cs.aspx I create the DB connection, create the typed dataset and table adapter, specify the sql, etc. When I add the code to the presentation layer (in this case a page called AllProducts.aspx) I am unable to find the NorthwindTableAdapters.ProductsTableAdapter class. I tried to import the NorthwindTableAdapters namespace, but it is not showing up. Looking in the solution explorer Class View confirms that there is a Northwind class, but not the namespace I'm looking for. I've tried several online tutorials that all have essentially the same steps, and I'm getting the same results. Can anyone give me a push in the right direction? I'm getting error: Namespace or type specified in the Imports 'NorthwindTableAdapters' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. I think I might need to add a reference OR they may be creating a separate class and importing it into their main project. If that's the case, the tutorials do not mention this.

• iPhone SDK linking errors with static library

  - by Nico

  Hello all! I've built my own static library with components to be reused in my project, and recently had the need to update a bunch of classes. Specifically, some methods' signatures were changed due to the fact that some classes changed names. What happens now is that the library compiles fine on its own, but, when added to an app project, the project fails to link: Ld build/Sucursales.build/Debug-iphoneos/Sucursales.build/Objects-normal/armv6/Sucursales normal armv6 cd /Users/nameghino/src/Sucursales setenv IPHONEOS_DEPLOYMENT_TARGET 3.1 setenv PATH "/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin:/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin" /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2 -arch armv6 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk -L/Users/nameghino/src/Sucursales/build/Debug-iphoneos -L/Users/nameghino/src/Sucursales/../../Library/MyLibraries/MSSharedLibrary-1.0.0 -F/Users/nameghino/src/Sucursales/build/Debug-iphoneos -filelist /Users/nameghino/src/Sucursales/build/Sucursales.build/Debug-iphoneos/Sucursales.build/Objects-normal/armv6/Sucursales.LinkFileList -dead_strip -lxml2 -ObjC -all_load -miphoneos-version-min=3.1 -framework Foundation -framework UIKit -framework CoreGraphics -lsqlite3.0 -framework CoreLocation -framework MapKit -lxml2 /Users/nameghino/src/MSSharedComponents/Frameworks/MSSharedLibrary/build/Debug-iphoneos/libMSSharedLibrary.a -o /Users/nameghino/src/Sucursales/build/Sucursales.build/Debug-iphoneos/Sucursales.build/Objects-normal/armv6/Sucursales Undefined symbols: "_OBJC_CLASS_$_DataCatalogService_GetSingleRow", referenced from: objc-class-ref-to-DataCatalogService_GetSingleRow in libMSSharedLibrary.a(MSDataCatalogSpecification.o) **"_OBJC_CLASS_$_DataCatalogService_ArrayOfString", referenced from: objc-class-ref-to-DataCatalogService_ArrayOfString in libMSSharedLibrary.a(MSDataCatalogSpecification.o) "_OBJC_CLASS_$_DataCatalogService_GetSingleRowResponse", referenced from: objc-class-ref-to-DataCatalogService_GetSingleRowResponse in libMSSharedLibrary.a(MSSingleRowResultsParser.o) "_OBJC_CLASS_$_DataCatalogService_GetMultiRowResponse", referenced from: objc-class-ref-to-DataCatalogService_GetMultiRowResponse in libMSSharedLibrary.a(MSMultiRowResultsParser.o) "_OBJC_CLASS_$_DataCatalogService_GetMultiRow", referenced from: objc-class-ref-to-DataCatalogService_GetMultiRow in libMSSharedLibrary.a(MSDataCatalogSpecification.o) "_OBJC_CLASS_$_DataCatalogService_HelloWorldResponse", referenced from: objc-class-ref-to-DataCatalogService_HelloWorldResponse in libMSSharedLibrary.a(DataCatalogService.o) ld: symbol(s) not found collect2: ld returned 1 exit status** The curious thing is that after a lot of project cleanups (both in the app and the lib projects), I still get the same issue.

• Fluent NHibernate is bringing ClassMap Id and SubClassMap Id to referenced table?

  - by Andy

  HI, I have the following entities I'm trying to map: public class Product { public int ProductId { get; private set; } public string Name { get; set; } } public class SpecialProduct : Product { public ICollection<Option> Options { get; private set; } } public class Option { public int OptionId { get; private set; } } And the following mappings: public class ProductMap : ClassMap<Product> { public ProductMap() { Id( x => x.ProductId ); Map( x => x.Name ); } public class SpecialProductMap : SubclassMap<SpecialProduct> { public SpecialProductMap() { Extends<ProductMap>(); HasMany( p => p.Options ).AsSet().Cascade.SaveUpdate(); } } public class OptionMap : ClassMap<Option> { public OptionMap() { Id( x => x.OptionId ); } } The problem is that my tables end up like this: Product -------- ProductId Name SpecialProduct -------------- ProductId Option ------------ OptionId ProductId // This is wrong SpecialProductId // This is wrong There should only be the one ProductId and single reference to the SpecialProduct table, but we get "both" Ids and two references to SpecialProduct.ProductId. Any ideas? Thanks Andy

• Populating Models from other Models in Django?

  - by JT

  This is somewhat related to the question posed in this question but I'm trying to do this with an abstract base class. For the purposes of this example lets use these models: class Comic(models.Model): name = models.CharField(max_length=20) desc = models.CharField(max_length=100) volume = models.IntegerField() ... <50 other things that make up a Comic> class Meta: abstract = True class InkedComic(Comic): lines = models.IntegerField() class ColoredComic(Comic): colored = models.BooleanField(default=False) In the view lets say we get a reference to an InkedComic id since the tracer, err I mean, inker is done drawing the lines and it's time to add color. Once the view has added all the color we want to save a ColoredComic to the db. Obviously we could do inked = InkedComic.object.get(pk=ink_id) colored = ColoredComic() colored.name = inked.name etc, etc. But really it'd be nice to do: colored = ColoredComic(inked_comic=inked) colored.colored = True colored.save() I tried to do class ColoredComic(Comic): colored = models.BooleanField(default=False) def __init__(self, inked_comic = False, *args, **kwargs): super(ColoredComic, self).__init__(*args, **kwargs) if inked_comic: self.__dict__.update(inked_comic.__dict__) self.__dict__.update({'id': None}) # Remove pk field value but it turns out the ColoredComic.objects.get(pk=1) call sticks the pk into the inked_comic keyword, which is obviously not intended. (and actually results in a int does not have a dict exception) My brain is fried at this point, am I missing something obvious, or is there a better way to do this?

• Spring Test / JUnit problem - unable to load application context

I am trying to use Spring Test to inject a customized bean into the test class. Here is my test-applicationContext.xml: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="............."> <bean id="MyUuidFactory" class="com.myapp.UuidFactory" scope="singleton" > <property name="typeIdentifier" value="CLS" /> </bean> <bean id="ThingyImplTest" class="com.myapp.ThingyImplTest" scope="singleton"> <property name="uuidFactory"> <idref local="MyUuidFactory" /> </property> </bean> </beans> The injection of MyUuidFactory instance goes along with the following code from within the test class: private UuidFactory uuidFactory; public void setUuidFactory(UuidFactory uuidFactory) { this.uuidFactory = uuidFactory; } However, when I go to run the test (in Eclipse or command line) I get the following error (stack trace omitted for brevity): Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'MyImplTest' defined in class path resource [test-applicationContext.xml]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'java.lang.String' to required type 'com.myapp.UuidFactory' for property 'uuidFactory'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [com.myapp.UuidFactory] for property 'uuidFactory': no matching editors or conversion strategy found Funny thing is, the Eclipse/Spring XML editor shows errors of I misspell any of the types or idrefs. If I leave the bean in, but comment out the dependency injection, everything work until I get a NullPointerException while running the test...which makes sense.

• jQuery hover menu not disappearing

  - by Nathan Loding

  I have a basic menu using some nested UL's, which is pretty standard I think. When hovering over an LI from the "root" menu, I want the UL within that LI to display. Move the mouse off or to another LI, it shows that submenu. Move down to the submenu and it stays while you hover over each element. I had it working with a simple jQuery.hover() set, but then I ran into issues. When on a page, the "root" menu item is given a class of 'current-page' and if that class exists, I want it to display that submenu statically after a mouseout. Hope I explained that well enough. I just tossed a variable into the hover functions so on the mouseout it ran a .show() on the current-page's submenu. Easy. Except that when I move the mouse between the individual LI's of the submenu, it changes back to the current-page submenu. So I attempted to add a timer element based on another question here. That made things worse -- now the submenus just don't disappear. Here's my CSS, markup, and JS ... how the heck do I make this work properly? Markup: <div id="menu"> <div id="navbar"> <ul id="firstmenu"> <li> <a href="http://localhost/site/pageone">page one</a> <ul class="submenu"> <li><a href="http://localhost/site/pageone/subone">subone</a></li> <li><a href="http://localhost/site/pageone/subtwo">subtwo</a></li> <li><a href="http://localhost/site/pageone/subthree">subthree</a></li> <li><a href="http://localhost/site/pageone/subfour">subfour</a></li> <li><a href="http://localhost/site/pageone/subfive">subfive</a></li> </ul> </li> <li> <a href="http://localhost/site/pagetwo">barely there</a> <ul class="submenu"> <li><a href="http://localhost/site/pageone/subone">subone</a></li> <li><a href="http://localhost/site/pageone/subtwo">subtwo</a></li> <li><a href="http://localhost/site/pageone/subthree">subthree</a></li> <li><a href="http://localhost/site/pageone/subfour">subfour</a></li> <li><a href="http://localhost/site/pageone/subfive">subfive</a></li> </ul> </li> <li class="current-page"> <a href="http://localhost/site/pagetwo">kith & kin</a> <ul class="submenu"> <li><a href="http://localhost/site/pageone/subone">subone</a></li> <li><a href="http://localhost/site/pageone/subtwo">subtwo</a></li> <li><a href="http://localhost/site/pageone/subthree">subthree</a></li> <li><a href="http://localhost/site/pageone/subfour">subfour</a></li> <li><a href="http://localhost/site/pageone/subfive">subfive</a></li> </ul> </li> <li> <a href="http://localhost/site/pagethree">focal point</a> <ul class="submenu"> <li><a href="http://localhost/site/pageone/subone">subone</a></li> <li><a href="http://localhost/site/pageone/subtwo">subtwo</a></li> <li><a href="http://localhost/site/pageone/subthree">subthree</a></li> <li><a href="http://localhost/site/pageone/subfour">subfour</a></li> <li><a href="http://localhost/site/pageone/subfive">subfive</a></li> </ul> </li> <li> <a href="http://localhost/site/pagefour">products</a> <ul class="submenu"> <li><a href="http://localhost/site/pageone/subone">subone</a></li> <li><a href="http://localhost/site/pageone/subtwo">subtwo</a></li> <li><a href="http://localhost/site/pageone/subthree">subthree</a></li> <li><a href="http://localhost/site/pageone/subfour">subfour</a></li> <li><a href="http://localhost/site/pageone/subfive">subfive</a></li> </ul> </li> <li> <a href="http://localhost/site/pagefive">clients</a> </li> </ul> </div></div> And here's the CSS: #navbar { margin: 0; padding: 0; border: 0; text-align: center; } #firstmenu { margin: 6px auto 0 auto; font-size: 16px; list-style-type: none; letter-spacing: -1px; } #firstmenu li { display: inline; position:relative; overflow: hidden; text-align: center; margin-right: 10px; padding: 5px 15px; } #firstmenu a { text-decoration: none; outline: none; color: black; font-weight: 700; width: 75px; cursor: pointer; } .current-page { color: white; background: url(../images/down_arrow.png) bottom center no-repeat; } .current-page a { color: white; border-bottom: 1px solid black; } #firstmenu .current-page a { color: white; } #firstmenu li.hover { color: white; background: url(../images/down_arrow.png) bottom center no-repeat; } #firstmenu li.hover a { color: white; border-bottom: 1px solid black; } #firstmenu li ul li.hover { color: white; background: none; } #firstmenu li ul li.hover a { color: white; border-bottom: none; text-decoration: underline; } #firstmenu li ul { width: 900px; color: white; font-size: .8em; margin-top: 3px; padding: 5px; position: absolute; display: none; } #firstmenu li ul li { list-style: none; display: inline; width: auto; } #firstmenu li ul li a { color: white; font-weight: normal; border: none; } .sub-current-page { font-weight: bold; text-decoration: underline; } #firstmenu li ul li.sub-current-page a { font-weight: bold; } And lastly, my not-at-all-working JS (this is in a $(document).ready(), of course): // Initialize some variables var hideSubmenuTimer = null; var current_page; $('.current-page ul:first').show(); // Prep the menu $('#firstmenu li').hover(function() { // Clear the timeout if it exists if(hideSubmenuTimer) { clearTimeout(hideSubmenuTimer); } // Check if there's a current-page class set if($('li.current-page').length > 0) { current_page = $('li.current-page'); } else { current_page = false; } // If there's a current-page class, hide it if(current_page) { current_page.children('ul:first').hide(); } // Show the new submenu $(this).addClass('hover').children('ul:first').show(); }, function(){ // Just in case var self = this; // Clear the timeout if it exists if(hideSubmenuTimer) { clearTimeout(hideSubmenuTimer); } // Check if there's a current-page class set if($('li.current-page').length > 0) { current_page = $('li.current-page'); } else { current_page = false; } // Set a timeout on hiding the submenu hideSubmenuTimer = setTimeout(function() { // Hide the old submenu $(self).removeClass('hover').children('ul').hide(); // If there's a current-page class, show it if(current_page) { current_page.children('ul:first').show(); current_page.css('color', 'white'); } }, 500); }); So what am I doing so wrong? As a side note, I'm using the $('.current-page ul:first').show() because if I gave .current-page any "display" setting in the CSS, it positioned it really weirdly on the page.

• Problem resolving a generic Repository with Entity Framework and Castle Windsor Container

  - by user368776

  Hi, im working in a generic repository implementarion with EF v4, the repository must be resolved by Windsor Container. First the interface public interface IRepository<T> { void Add(T entity); void Delete(T entity); T Find(int key) } Then a concrete class implements the interface public class Repository<T> : IRepository<T> where T: class { private IObjectSet<T> _objectSet; } So i need _objectSet to do stuff like this in the previous class public void Add(T entity) { _objectSet.AddObject(entity); } And now the problem, as you can see im using a EF interface like IObjectSet to do the work, but this type requires a constraint for the T generic type "where T: class". That constrait is causing an exception when Windsor tries to resolve its concrete type. Windsor configuration look like this. <castle> <components> <component id="LVRepository" service="Repository.Infraestructure.IRepository`1, Repository" type="Repository.Infraestructure.Repository`1, Repository" lifestyle="transient"> </component> </components> The container resolve code IRepository<Product> productsRep =_container.Resolve<IRepository<Product>>(); Now the exception im gettin System.ArgumentException: GenericArguments[0], 'T', on 'Repository.Infraestructure.Repository`1[T]' violates the constraint of type 'T'. ---> System.TypeLoadException: GenericArguments[0], 'T', on 'Repository.Infraestructure.Repository`1[T]' violates the constraint of type parameter 'T'. If i remove the constraint in the concrete class and the depedency on IObjectSet (if i dont do it get a compile error) everything works FINE, so i dont think is a container issue, but IObjectSet is a MUST in the implementation. Some help with this, please.
