  • Grails: Services VS Groovy classes

    - by Olexandr
    Documentation says: The Grails team discourages the embedding of core application logic inside controllers, as it does not promote re-use and a clean separation of concerns. I have one API controller and a few Groovy classes in src/groovy folder. Those classes just implements my application logic so actions in API controller works in this way: //index page def index = { render new IndexApi().index(params) as JSON } I'm curious - is there any reason to move my application logic from plain groovy classes into services ?

  • Generating ActionScript value objects from middle-tier Java classes

    - by eli
    In a Flex / Java app stack using remoting (via BlazeDS), classes to hold data passed back and forth between client and server need to be maintained in both the client (in ActionScript) and server (in Java). I want a way to maintain theses classes in Java only, and have the corresponding ActionScript value object classes generated by the build process.

  • Generate EF4 POCO classes first time only

    - by Jaxidian
    The problem I'm having is, using the POCO templates, generating my POCO classes the first time only and not overwriting them when the templates are re-ran. I know this sounds hokey and the reason is that I'm actually changing these templates and trying to generate metadata classes rather than the actual POCO classes, but these metadata classes will be hand-edited and I want to keep those edits in the future but still regenerate a certain amount of it. I have it all working exactly as I want except for the regeneration of the files. I have looked into T4 and it seems that there is a flag to do just this (see the Output.PreserveExistingFile property) but I don't understand where/how to set this flag. If you can tell me where/how to set this in the default POCO templates, then I think that's all I really need. Thanks!! :-)

  • Objective-C: Getting the True Class of Classes in Class Clusters

    - by TechZen
    Recently while trying to answer a questions here, I ran some test code to see how Xcode/gdb reported the class of instances in class clusters. (see below) In the past, I've expected to see something like: PrivateClusterClass:PublicSuperClass:NSObject Such as this (which still returns as expected): NSPathStore2:NSString:NSObject ... for a string created with +[NSString pathWithComponents:]. However, with NSSet and subclass the following code: - (void)applicationDidFinishLaunching:(UIApplication *)application { NSSet *s=[NSSet setWithObject:@"setWithObject"]; NSMutableSet *m=[NSMutableSet setWithCapacity:1]; [m addObject:@"Added String"]; NSMutableSet *n = [[NSMutableSet alloc] initWithCapacity:1]; [self showSuperClasses:s]; [self showSuperClasses:m]; [self showSuperClasses:n]; [self showSuperClasses:@"Steve"]; } - (void) showSuperClasses:(id) anObject{ Class cl = [anObject class]; NSString *classDescription = [cl description]; while ([cl superclass]) { cl = [cl superclass]; classDescription = [classDescription stringByAppendingFormat:@":%@", [cl description]]; } NSLog(@"%@ classes=%@",[anObject class], classDescription); } ... outputs: // NSSet *s NSCFSet classes=NSCFSet:NSMutableSet:NSSet:NSObject //NSMutableSet *m NSCFSet classes=NSCFSet:NSMutableSet:NSSet:NSObject //NSMutableSet *n NSCFSet classes=NSCFSet:NSMutableSet:NSSet:NSObject // NSString @"Steve" NSCFString classes=NSCFString:NSMutableString:NSString:NSObject The debugger shows the same class for all Set instances. I know that in the past the Set class cluster did not return like this. What has changed? (I suspect it is a change in the bridge from Core Foundation.) What class cluster report just a generic class e.g. NSCFSet and which report an actual subclass e.g. NSPathStore2? Most importantly, when debugging how do you determine the actual class of a NSSet cluster instance?

  • Dynamic access of classes of a given namespace

    - by user322383
    Hi! I'm writing an interface that will be implemented by a lot of classes, and I'm writing a class that will hold a collection of instances of these implementations. Every class will have a default constructor. So, is there a simple way (e.g. using some kind of reflection) to put an instance of each of these implementing classes to the collection? Besides doing it manually, which is simple, yes, but a lot of work and error prone (what if I missed an implementation while writing the method? What if a new implementation came and I forgot to update the given method?). So, what I would like is to be able to iterate through all classes of a given namespace or maybe through the list of all available classes. My method then would simply check, through reflection, if the given class implements the given interface, and if it does, puts it into the collection. Thank you.

  • Hibernate: Querying objects by attributes of inherited classes

    - by MichaelD
    Hi all, I ran into a problem with Hibernate concerning queries on classes which use inheritance. Basically I've the following class hierarchy: @Entity @Table( name = "recording" ) class Recording { ClassA attributeSet; ... } @Entity @Inheritance( strategy = InheritanceType.JOINED ) @Table( name = "classA" ) public class ClassA { String Id; ... } @Entity @Table( name = "ClassB1" ) @PrimaryKeyJoinColumn( name = "Id" ) public class ClassB1 extends ClassA { private Double P1300; private Double P2000; } @Entity @Table( name = "ClassB2" ) @PrimaryKeyJoinColumn( name = "Id" ) public class ClassB2 extends ClassA { private Double P1300; private Double P3000; } The hierarchy is already given like this and I cannot change it easily. As you can see ClassB1 and ClassB2 inherit from ClassA. Both classes contain a set of attributes which sometimes even have the same names (but I can't move them to ClassA since there are possible more sub-classes which do not use them). The Recording class references one instance of one of this classes. Now my question: What I want to do is selecting all Recording objects in my database which refer to an instance of either ClassB1 or ClassB2 with e.g. the field P1300 == 15.5 (so this could be ClassB1 or ClassB2 instances since the P1300 attribute is declared in both classes). What I tried is something like this: Criteria criteria = session.createCriteria(Recording.class); criteria.add( Restrictions.eq( "attributeSet.P1300", new Double(15.5) ) ); criteria.list(); But since P1300 is not an attribute of ClassA hibernate throws an exception telling me: could not resolve property: P1300 of: ClassA How can I tell hibernate that it should search in all subclasses to find the attribute I want to filter? Thanks MichaelD

  • Do Hibernate table classes need to be Serializable?

    - by Scott Leis
    I have inherited a Websphere Portal project that uses Hibernate 3.0 to connect to a SQL Server database. There are about 130 Hibernate table classes in this project. They all implement Serializable. None of them declare a serialVersionUID field, so the Eclipse IDE shows a warning for all of these classes. Is there any actual need for these classes to implement Serializable? If so, is there any tool to add a generated serialVersionUID field to a large number of classes at once (just to make the warnings go away) ?

  • Modularity Java: top level vs. nested classes

    - by an00b
    The Java tutorials that I read, like to use nested classes to demonstrate a concept, a feature or use. This led me to initially implement a sample project I created just like that: Lots of nested classes in the main activity class. It works, but now I got a monstrous monolithic .java file. I find it somewhat inconvenient and I now intend to break to multiple .java files/classes. It occurred to me, however, that sometimes there may be reasons not to take classes out of their enclosing class. If so, what are good reasons to keep a module large, considering modularity and ease of maintenance?

  • What is the purpose of abstract classes?

    - by SpikETidE
    I am trying to learn OOP in PHP, and I have some confusion about interfaces and abstract classes. They both contain no implementations, only definitions, and should be implemented through their sub-classes. What part of abstract classes clearly distinguishes them from interfaces? Also, due to their apparent similarities, based on what reasons should I decide to use one over the other?

  • Referring to a non-final variable data inside an inner class

    - by shoaibmohammed
    Im doing a program in GWT. Here is the snippet where Im having problem private String[] populateRSSData() { 1==>> String[] data = null; try { new RequestBuilder(RequestBuilder.GET, "../database.php?action=populaterss").sendRequest(null, new RequestCallback() { @Override public void onResponseReceived(Request request, Response response) { 2==>> data=response.getText().split("~"); } @Override public void onError(Request request, Throwable exception) { Window.alert(exception.getMessage()); } }); } catch (RequestException e) { Window.alert(e.getMessage()); } return data; } Now the problem arises that I get an error that the variable 1==>> data should be declared final. But if I declare it as final then i cannot store the datas in 2==>> The error i get Cannot refer to a non-final variable data inside an inner class defined in a different method RSS_Manager.java Please suggest

  • Passing arguments to anonymous inner classes

    - by synic
    I'm trying to make an API library for our web services, and I'm wondering if it's possible to do something like this: abstract class UserRequest(val userId: Int) { def success(message: String) def error(error: ApiError) } api.invokeRequest(new UserRequest(121) { override def success(message: String) = { // handle success } override def error(error: ApiError) = { // handle the error } } I'm talking about passing parameters to the anonymous inner class, and also overriding the two methods. I'm extremely new to Scala, and I realize my syntax might be completely wrong. I'm just trying to come up with a good design for this library before I start coding it. I'm willing to take suggestions for this, if I'm doing it the completely wrong way, or if there's a better way. The idea is that the API will take some sort of request object, use it to make a request in a thread via http, and when the response has been made, somehow signal back to the caller if the request was a success or an error. The request/error functions have to be executed on the main thread.

  • Int PK inner join Vs Guid PK inner Join on SQL Server. Execution plan.

    - by bigb
    I just did some testing for Int PK join Vs Guid PK. Tables structure and number of records looking like that: Performance of CRUD operations using EF4 are pretty similar in both cases. As we know Int PK has better performance rather than strings. So SQL server execution plan with INNER JOINS are pretty different Here is an execution plan. As i understand according with execution plan from attached image Int join has better performance because it is taking less resources for Clustered index scan and it is go in two ways, am i right? May be some one may explain this execution plan in more details?

  • How to disable sql creation for JPA entity classes

    - by Samuel
    We have some JPA entity classes which are currently under development and wouldn't want them as part of the testing cycle. We tried commenting out the relevant entity classes in META-INF\persistence.xml but the hbm2ddl reverse engineering tool still seems to generate SQL for those entities. How do I tell my code to ignore these classes? Are there any annotations for these or should I have to comment out the @Entity annotation along with my changes in persistence.xml file.

  • Using methods from the "outer" class in inner classes

    - by devoured elysium
    When defining nested classes, is it possible to access the "outer" class' methods? I know it's possible to access its attributes, but I can't seem to find a way to use its methods. addMouseListener(new MouseAdapter() { @Override public void mouseClicked(MouseEvent e) { if (e.getClickCount() == 2 && //<-- Here I'd like to } // reference a method }); //from the class where //addMouseListener() is defined! Thanks

  • designing classes and objects in .net for a restaurant assignment

    - by Dell Boy
    I have received an assignment at School for creating a Restaurant site. I have to use objects and classes (OOP) for my assignment. I have the foundations of the OOP in .net, but what I don't know is how can I design this assignment to be object-oriented. I don't know how to start it. The requirement is like this: The menu has to be saved in a database and retrieved from it. The menu is devided in appetizers, Salades, Main Meal, Pastas, Wines, Beverages, Extras, Do I create classes like this: Base Class: Menu Derived classes: Appetizers, Salades, Main meal, Pastas, wines, etc. If you have a good example about how to create classes from a Menu that will be great. You don't have to rely on the example I gave above. The menu can be anything. I can deside what the menu will contain. thanks a lot. I am waiting for some help. Please

  • Access inner function variables in Javascript

    - by Elazar Leibovich
    In many frameworks, internal function variables are used as private variables, for example Raphael = (function(){ var private = function(a,b) {return a+b;}; var public = function(a) {return private(a,a);} var object = {mult2:public}; return object; })(); here, we cannot access from the global namespace the variable named private, as it is an inner variable of the anonymous function in the first line. Sometimes this function is contains a big Javascript framework, so that it wouldn't pollute the global namespace. I need to unit tests some object Raphael uses internally (in the above example, I wish to run unit tests on the object private). How can I test them?

  • When did C++ get nested classes?

    - by Parappa
    Somehow I never noticed until today that C++ supports nested classes. This surprised me because when I was learning C++ back in the '90s, I specifically remember nested classes being something that Object Pascal and Java had, but which C++ did not. I asked an old programmer friend about it and he concurred that he recalls C++ not having nested classes. Is my recollection of C++ not having nested classes mistaken, or were they actually added to the standard at some point in the past fifteen years? I tried searching Google for information on this topic and I haven't come up with anything helpful yet. It could also be that I'm thinking of nested functions, which Pascal certainly supports but C does not.

  • C# VS 2008 Build Configurations - using different classes for different builds

    - by evan
    I'm writing an application which has two classes that provide basically the same functionality but for different situations. I'd like to have three versions of the software - one where the user can change an ini file to configure the program to use one of the two classes, and then one version that only uses one of the two classes. Right now I have it working via an ini file, but I'd like to be able to build versions that don't include the code for the unneeded class at all. What is the best way to go about this? My current line of thinking is that since both classes derive from a common interface I'll just add a compile time conditional that looks at the active build configuration and decides whether to compile that class. What is the syntax to do that? Thanks in advance for your help and input!

  • Access asp:CheckBox inner input from jQuery

    I have a jQuery array acting on each control having corresponding class: function Foobar() { $('.foo').each(function() { // do something with $(this) } } I can access client-side controls like <input class="foo"> and server-side controls like asp:TextBox CassClass="foo"> But setting CssClass for asp:RadioButton doesn't make a sense. Here is generated code: <span class="foo"> <input type="radio" /> </span> How to set class for inner input or another way gather it using jQuery?
