  • LaTeX: Multiple authors in a two-column article

    - by Amro
    I'm kind of new to LaTeX and I am having a bit of a problem.. I am using a twocolumn layout for my article. There are four authors involved with different affiliations, and I am trying to list all of them under the title so they span the entire width of the page (all on the same level). It should be similar to this: Article Title auth1FN auth1LN 2 ... 3 auth4FN auth4LN department ... department school ... school email@edu ... email@edu Abstract ..................... .................... ..................... .................... ..................... .................... ..................... Currently I have something along the lines: \documentclass[10pt,twocolumn]{article} \usepackage{multicol} \begin{document} \begin{multicols}{2} \title{Article Title} \author{ First Last\\ Department\\ school\\ email@edu \and First Last\\ ... } \date{} \maketitle \end{multicols} \begin{abstract} ... \end{abstract} \section{Introduction} ... \end{document} The problem is that the authors are not displayed all on the same level, instead I get the first three next to each other, followed by the last one underneath. Is there way to achieve what I want? Also if possible, how can I customize the font of the affiliations (to be smaller and in italic)?

  • How to achieve "Blendability" when using DataServiceCollection in my ViewModel

    - by andlju
    I'm looking at using oData endpoints in my Silverlight client. Naturally, I'm doing MVVM and I want the project to be nice and "Blendable" (i.e. I must be able to cleanly use static data instead of the oData endpoints when in design mode.) Now to the problem. I'd like to use the DataServiceCollection in my ViewModels, since it allows for nice bindable collections without having to worry too much with BeginExecute/EndExecute etc. Now, let's look at some code. My Model interface looks like this: public interface ITasksModel { IQueryable<Task> Tasks { get; } } The oData endpoint implementation of that interface: public class TasksModel : ITasksModel { Uri svcUri = new Uri("http://localhost:2404/Services/TasksDataService.svc"); TaskModelContainer _container; public TasksModel() { _container = new TaskModelContainer(svcUri); } public IQueryable<Task> Tasks { get { return _container.TaskSet; } } } And the "Blendable" design-time implementation: public class DesignModeTasksModel : ITasksModel { private List<Task> _taskCollection = new List<Task>(); public DesignModeTasksModel() { _taskCollection.Add(new Task() { Id = 1, Title = "Task 1" }); _taskCollection.Add(new Task() { Id = 2, Title = "Task 2" }); _taskCollection.Add(new Task() { Id = 3, Title = "Task 3" }); } public IQueryable<Task> Tasks { get { return _taskCollection.AsQueryable(); } } } However, when I try to use this last one in my ViewModel constructor: public TaskListViewModel(ITasksModel tasksModel) { _tasksModel = tasksModel; _tasks = new DataServiceCollection<Task>(); _tasks.LoadAsync(_tasksModel.Tasks); } I get an exception: Only a typed DataServiceQuery object can be supplied when calling the LoadAsync method on DataServiceCollection. First of all, if this is the case, why not make the input parameter of LoadAsync be typed as DataServiceQuery? Second, what is the "proper" way of doing what I'm trying to accomplish?

  • "cloud architecture" concepts in a system architecture diagrams

    - by markus
    If you design a distributed application for easy scale-out, or you just want to make use of any of the new “cloud computing” offerings by Amazon, Google or Microsoft, there are some typical concepts or components you usually end up using: distributed blob storage (aka S3) asynchronous, durable message queues (aka SQS) non-Relational-/non-transactional databases (like SimpleDB, Google BigTable, Azure SQL Services) distributed background worker pool load-balanced, edge-service processes handling user requests (often virtualized) distributed caches (like memcached) CDN (content delivery network like Akamai) Now when it comes to design and sketch an architecture that makes use of such patterns, are there any commonly used symbols I could use? Or even a download with some cool Visio stencils? :) It doesn’t have to be a formal system like UML but I think it would be great if there were symbols that everyone knows and understands, like we have commonly used shapes for databases or a documents, for example. I think it would be important to not mix it up with traditional concepts like a normal file system (local or network server/SAN), or a relational database. Simply speaking, I want to be able to draw some conclusions about an application’s scalability or data consistency issues by just looking at the system architecture overview diagram. Update: Thank you very much for your answers. I like the idea of putting a small "cloud symbol" on the traditional symbols. However I leave this thread open just in case someone will find specific symbols (maybe in a book or so) - or uploaded some pimped up Visio stencils ;)

  • VS2010 - How to automatically stop compile on first compile error

    - by Ben Robbins
    {rant}First I'd like to say that this IS NOT A DUPLICATE. I've asked this question previously but it got closed as a duplicate when it isn't. This question is SPECIFIC to VS 2010 and the answers to the so-called duplicate work in VS 2008 but not in VS 2010 (at least not for me or anyone I know). So before you go closing something as a duplicate how about you read the question carefully and try the answer for yourself and see if it actually works. Apologies for the rant but there is no obvious way to contact the SO police that closed the issue or get it reopened. {/rant} At work we have a C# solution with over 80 projects. In VS 2008 we use a macro to stop the compile as soon as a project in the solution fails to build (see this question for several options for VS 2005 & VS 2008: http://stackoverflow.com/questions/134796/how-to-automatically-stop-visual-c-build-at-first-compile-error). Is it possible to do the same in VS 2010? What we have found is that in VS 2010 the macros don't work (at least I couldn't get them to work) as it appears that the environment events don't fire in VS 2010. The default behaviour is to continue as far as possible and display a list of errors in the error window. I'm happy for it to stop either as soon as an error is encountered (file-level) or as soon as a project fails to build (project-level). Answers for VS 2010 only please. If the macros do work then a detailed explanation of how to configure them for VS 2010 would be appreciated. Thanks.

  • Thread-safe data structures

    - by Inso Reiges
    Hello, I have to design a data structure that is to be used in a multi-threaded environment. The basic API is simple: insert element, remove element, retrieve element, check that element exists. The structure's implementation uses implicit locking to guarantee the atomicity of a single API call. After i implemented this it became apparent, that what i really need is atomicity across several API calls. For example if a caller needs to check the existence of an element before trying to insert it he can't do that atomically even if each single API call is atomic: if(!data_structure.exists(element)) { data_structure.insert(element); } The example is somewhat awkward, but the basic point is that we can't trust the result of exists call anymore after we return from atomic context (the generated assembly clearly shows a minor chance of context switch between the two calls). What i currently have in mind to solve this is exposing the lock through the data structure's public API. This way clients will have to explicitly lock things, but at least they won't have to create their own locks. Is there a better commonly-known solution to these kinds of problems? And as long as we're at it, can you advise some good literature on thread-safe design? Thank you.

  • Support for nested model and class validation with ASP.NET MVC 2.0

    - by Diep-Vriezer
    I'm trying to validate a model containing other objects with validation rules using the System.ComponentModel.DataAnnotations attributes was hoping the default MVC implementation would suffice: var obj = js.Deserialize(json, objectInfo.ObjectType); if(!TryValidateModel(obj)) { // Handle failed model validation. } The object is composed of primitive types but also contains other classes which also use DataAnnotications. Like so: public class Entry { [Required] public Person Subscriber { get; set; } [Required] public String Company { get; set; } } public class Person { public String FirstName { get; set;} [Required] public String Surname { get; set; } } The problem is that the ASP.NET MVC validation only goes down 1 level and only evaluates the properties of the top level class, as can be read on digitallycreated.net/Blog/54/deep-inside-asp.net-mvc-2-model-metadata-and-validation. Does anyone know an elegant solution to this? I've tried xVal, but they seem to use a non-recursive pattern (http://blog.stevensanderson.com/2009/01/10/xval-a-validation-framework-for-aspnet-mvc/). Someone must have run into this problem before right? Nesting objects in your model doesn't seem so weird if you're designing a web service.

  • T4 vs CodeDom vs Oslo

    - by Ryan Riley
    In an application scaffolding project on which I'm working, I'm trying to decide whether to use Oslo, T4 or CodeDom for generating code. Our goals are to keep dependencies to a minimum and drive code generation for a domain driven design from user stories. The first step will be to create the tests from the user stories, but we want the domain experts to be able to write their stories in a variety of different media (e.g. custom app, Word, etc.) and still generate the tests from the stories. What I know so far: CodeDom requires .NET but can only output .NET class files (e.g. .cs, .vb). Level of difficulty is fairly high. T4 requires CodeDom and VS Standard+. Level of difficulty is fairly reasonable, especially with the T4 Toolbox. Oslo is very new. I have no idea of the dependencies, but I imagine you must be on at least .NET 3.5. I'm also not certain as to the code generation abilities or the complexity for adding new grammars. However, domain experts could probably write user stories in Intellipad quite easily. Also not sure about ease of converting stories in Word to an MGrammar. What are your thoughts, experiences, etc. with any of the above tools. We want to stick with Microsoft or open source tools.

  • WCF Manual SOAP POST using HttpWebRequest over https with Usertoken

    - by VonBlender
    Hi, I'm writing a client that calls a number of WCF webservices (written externallyt to my company) that are very similar in structure. The design I was hoping to use is to manually build the SOAP message from XML chunks that are stored in a database and then processed through a generic web service handler class. I have access to the WSDL's for each webservice and example working XML. The design approach is such that we can easily add to the message dynamically, hence the reason for not using the auto generated proxy classes I am basically at the last part now with the entire SOAP message constructed but am getting a SOAP fault security error returned. I have used fiddler to compare the message I'm sending with one that is sent using the normal (far simpler...) WCF generated proxy classes and can't see any difference apart from the id attribute of the Usertoken element in the SOAP header. This is where my lack of experience in this area isn't helping. I think this is because the id is generated automatically (presumably because we're using https). My question is how do I generate this programatically? I have searched for hours online but the majority of solutions are either using the proxy classes or not over https. I have briefly looked at WCE but aware this is replaced by WCF now so don't want to waste time looking into this if it's not the solution. Any help with this would be greatly appreciated. I can post some code examples when I'm back in work if it will help but the method I'm using is very straightforward and only using XElements and such like at the moment (as we're using linq to sql). thanks, Andy

  • LinearLayout not expanding inside a ScrollView

    - by Felix
    I have a LinearLayout inside a ScrollView that has android:layout_height="fill_parent", but it doesn't expand to the full height of the ScrollView. My layout looks something like: level layout layout_width layout_height 1 LinearLayout fill_parent fill_parent 2 LinearLayout fill_parent wrap_content 3 (some irrelevant stuff) 2 ScrollView fill_parent fill_parent <-- this expands full height 3 LinearLayout fill_parent fill_parent <-- this does not (has orientation=vertical) (following stuff probably are irrelevant, but just to be sure:) 4 TextView fill_parent fill_parent 4 LinearLayout fill_parent wrap_content I can see that the LinearLayout doesn't expand the full height of the ScrollView because in Eclipse in Android Layout Editor, if I select the ScrollView (in the Outline panel) it is highlighted with a red border that fills the screen to the bottom but when I select the LinearLayout its highlight doesn't expand to the bottom of the screen. How can I get it to do so? The effect I'm trying to achieve is to have some text and a button below it (inside the LinearLayout in level 4 there's just a button). The text can be big enough to need a scrollbar, in which case I want the user to have to scroll down in order to see the button. In case the text is not big enough for a scroll bar, I want the LinearLayout containing the button to stick to the bottom of the screen.

  • Exporting from SSRS 2008 ReportViewer to Excel Causes Duplicate Columns

    - by Daniel Coffman
    I have a report that groups months by quarters, so each quarter has three months and the display of the months under the quarter is toggled by the quarter header. It looks just fine in the ReportViewer, but when exporting to Excel the first month in the quarter with data is duplicated and appended to the end of the quarter group. Here is what it looks like in the ReportViewer (with Quarters 2 and 4 expanded, note May and June do not have any data and show blank columns by design): http://i.imgur.com/MykZE.png This is how it looks when exported to Excel: http://i.imgur.com/zfLuk.png The collapsed Quarter should only show the LAST month in the quarter. You can see that in the Excel export July is inserted in Q1 even though it should be hidden entirely since that quarter is collapsed, December is appended to Q2, January is inserted into Q3, and April is duplicated and appended to Q4. Exporting the any format OTHER than Excel works correctly and does not insert these columns. A similar bug for rows was filed and marked as "by design": http://connect.microsoft.com/SQLServer/feedback/details/508823/reporting-services-2008-group-by-export-to-excel-duplicate-rows-csv-ok-pdf-ok How do I stop the export to Excel feature from inserting these duplicate columns?

  • Problem using Flash Components in multiple SWC files

    - by Ken Dunnington
    [Edit: Short version - how do you properly handle namespace collisions in SWC files if one SWC has fewer classes from that namespace than another?] I have a rather large Flash application which I'm building in Flash Builder (because coding/debugging in the Flash IDE is... not good) and I've got a ton of external SWC files which I'm linking in to my application. This has worked well so far - the file size is on the large side, but it's a lot simpler than loading in SWFs, especially since I am extending most of the classes in each SWC and adding custom code that way (it's a very design-heavy app.) The problem I'm having is when I have Flash Components, like ComboBox or TextInput, in more than one SWC. Whichever SWC was compiled last will work fine, but the others will fail with errors like the following: TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::MovieClip@1f21adc1 to fl.controls.TextInput. at flash.display::Sprite/constructChildren() at flash.display::Sprite() at flash.display::MovieClip() at com.company.design.login::LoginForm() at com.company.view::Login()[/Users/ken/Workspace/src/com/company/view/Login.as:22] at com.company.view::Main/showLogin()[/Users/ken/Workspace/src/com/company/view/Main.as:209] at flash.events::EventDispatcher/dispatchEventFunction() at flash.events::EventDispatcher/dispatchEvent() at com.company.view::Navigation/handleUIClick()[/Users/ken/Workspace/src/com/company/view/Navigation.as:88] I've been researching components, ComponentShim, etc. but I'm running up against a brick wall. I thought it might be the fact that some of the components had their skins modified in the source FLA, so I tried replacing them with the default skins, but that didn't seem to help. How can I ensure that I have the components imported and available to all my classes, yet still be able to skin them and include them in my various FLAs? (I am never creating new instances of them, they are all laid out by my designer.)

  • Examples of localization in Perl using gettext and Locale::TextDomain, with fallback if Locale::Text

    - by Jakub Narebski
    The "On the state of i18n in Perl" blog post from 26 April 2009 recommends using Locale::TextDomain module from libintl-perl distribution for l10n / i18n in Perl. Besides I have to use gettext anyway, and gettext support in Locale::Messages / Locale::TextDomain is more natural than in gettext emulation in Locale::Maketext. The subsection "15.5.18 Perl" in chapter "15 Other Programming Languages" in GNU gettext manual says: Portability The libintl-perl package is platform independent but is not part of the Perl core. The programmer is responsible for providing a dummy implementation of the required functions if the package is not installed on the target system. However neither of two examples in examples/hello-perl in gettext sources (one using lower level Locale::Messages, one using higher level Locale::TextDomain) includes detecting if the package is installed on the target system, and providing dummy implementation if it is not. What is complicating matter (with respect to detecting if package is installed or not) is the following fragment of Locale::TextDomain manpage: SYNOPSIS use Locale::TextDomain ('my-package', @locale_dirs); use Locale::TextDomain qw (my-package); USAGE It is crucial to remember that you use Locale::TextDomain(3) as specified in the section "SYNOPSIS", that means you have to use it, not require it. The module behaves quite differently compared to other modules. Could you please tell me how one should detect if libintl-perl is present on target system, and how to provide dummy fallthrough implementation if it is not installed? Or give examples of programs / modules which do this?

  • Source-to-source compiler framework wanted

    - by cheungcc_2000
    Dear all, I used to use OpenC++ (http://opencxx.sourceforge.net/opencxx/html/overview.html) to perform code generation like: Source: class MyKeyword A { public: void myMethod(inarg double x, inarg const std::vector<int>& y, outarg double& z); }; Generated: class A { public: void myMethod(const string& x, double& y); // generated method below: void _myMehtod(const string& serializedInput, string& serializedOutput) { double x; std::vector<int> y; // deserialized x and y from serializedInput double z; myMethod(x, y, z); } }; This kind of code generation directly matches the use case in the tutorial of OpenC++ (http://www.csg.is.titech.ac.jp/~chiba/opencxx/tutorial.pdf) by writing a meta-level program for handling "MyKeyword", "inarg" and "outarg" and performing the code generation. However, OpenC++ is sort of out-of-date and inactive now, and my code generator can only work on g++ 3.2 and it triggers error on parsing header files of g++ of higher version. I have looked at VivaCore, but it does not provide the infra-structure for compiling meta-level program. I'm also looking at LLVM, but I cannot find documentation that tutor me on working out my source-to-source compilation usage. I'm also aware of the ROSE compiler framework, but I'm not sure whether it suits my usage, and whether its proprietary C++ front-end binary can be used in a commercial product, and whether a Windows version is available. Any comments and pointers to specific tutorial/paper/documentation are much appreciated.

  • General Web Programming/designing Question: ?

    - by Prasad
    hi, I have been in web programming for 2 years (Self taught - a biology researcher by profession). I designed a small wiki with needed functionalities and a scientific RTE - ofcourse lot is expected. I used mootools framework and AJAX extensively. I was always curious when ever I saw the query strings passed from URL. Long encrypted query string directly getting passed to the server. Especially Google's design is such. I think this is the start of providing a Web Service to a client - I guess. Now, my question is : is this a special, highly professional, efficient / advanced web design technique to communicate queries via the URL ? I always felt that direct URL based communication is faster. I tried my bit and could send a query through the URL directly. here is the link: http://sgwiki.sdsc.edu/getSGMPage.php?8 By this , the client can directly link to the desired page instead of searching and / or can automate. There are many possibilities. The next request: Can I be pointed to such technique of web programming? oops: I am sorry, If I have not been able to convey my request clearly. Prasad.

First of all, we're a small firm and there are only 3-4 developers, one of which is our boss who isn't really a programmer, he just chimes in now and then and tries to do code some simple things. The biggest problems are: Major cowboy coding and lack of methodologies. I've tried explaining to everyone the benefits of TDD and unit testing, but I only got weird looks as if I'm talking nonsense. Even the boss gave me the reaction along the lines of "why do we need that? it's just unnecessary overhead and a waste of time". Nobody uses design patterns. I have to tell people not to write business logic in code behind, I have to remind them not to hardcode concrete implementations and dependencies into classes and cetera. I often feel like a nazi because of this and people think I'm enforcing unnecessary policies and use of design patterns. The biggest problem of all is that people don't even respect common sense security policies. I've noticed that college students who work on tech support use our continuous integration and source control server as a dump to store their music, videos, series they download from torrents and so on. You can imagine the horror when I realized that most of the partition reserved for source control backups was used by entire seasons of TV series and movies. Our development server isn't even connected to an UPS and surge protection. It's just plugged straight into the wall outlet. I asked the boss to buy surge protection, but he said it's unnecessary. All in all, I like working here because the atmosphere is very relaxed, money is good and we're all like a family (so don't advise me to quit), but I simply don't know how to explain to people that they need to stick to some standards and good practices in IT industry and that they can't behave so irresponsibly. Thanks for the advice

  • UML class diagram vs ER database diagram

    - by salva84
    Hi, I'm a little confused, I'm developing a program, the program consist in two parts, the server and the clients, there are groups, places, messages... stored in the server, and the clients has to connect with it. I've design the use cases diagram, the activity diagrams, and I have design the class diagram too. The thing is that I want to implement the server in a mysql tables for storing the users, groups, places... users in groups... so I've designed a E-R diagram consisting in 6 tables, but the problem is that I think that my class diagram and my ER diagram looks too similar, I mean, I think I'm not doing things right because I have a class for each table practically, and when I have to extract all the users on my system, do I have to convert all the rows into objects at first and write in the database for each object modified? The easy choice for me would be to base my whole application only in the database, and making a class to extract and insert data in it, but I have to follow the UML specification and I'm a little confused what to do with the class diagram, because the books I have read say that I have to create a class for each "entity" of my program. Sorry for my bad English. Thank you.

  • Static factory pattern with EJB3/JBoss

    - by purecharger
    I'm fairly new to EJBs and full blown application servers like JBoss, having written and worked with special purpose standalone Java applications for most of my career, with limited use of JEE. I'm wondering about the best way to adapt a commonly used design pattern to EJB3 and JBoss: the static factory pattern. In fact this is Item #1 in Joshua Bloch's Effective Java book (2nd edition) I'm currently working with the following factory: public class CredentialsProcessorFactory { private static final Log log = LogFactory.getLog(CredentialsProcessorFactory.class); private static Map<CredentialsType, CredentialsProcessor> PROCESSORS = new HashMap<CredentialsType, CredentialsProcessor>(); static { PROCESSORS.put(CredentialsType.CSV, new CSVCredentialsProcessor()); } private CredentialsProcessorFactory() {} public static CredentialsProcessor getProcessor(CredentialsType type) { CredentialsProcessor p = PROCESSORS.get(type); if(p == null) throw new IllegalArgumentException("No CredentialsProcessor registered for type " + type.toString()); return p; } However, in the implementation classes of CredentialsProcessor, I require injected resources such as a PersistenceContext, so I have made the CredentialsProcessor interface a @Local interface, and each of the impl's marked with @Stateless. Now I can look them up in JNDI and use the injected resources. But now I have a disconnect because I am not using the factory anymore. My first thought was to change the getProcessor(CredentialsType) method to do a JNDI lookup and return the SLSB instance that is required, but then I need to configure and pass the proper qualified JNDI name. Before I go down that path, I wanted to do more research on accepted practices. How is this design pattern treated in EJB3 / JEE?

  • Bing maps silverlight control pushpin scaling problems.

    - by Rares Musina
    Baiscally my problem is that i've adapted a piece of code found here http://social.msdn.microsoft.com/Forums/en-US/vemapcontroldev/thread/62e70670-f306-4bb7-8684-549979af91c1 which does exactly what I want it to do, that is scale some pushpin images according to the map's zoom level. The only problem is that I've adapted this code to run with the bing maps silverlight control (not virtual earth like in the original example) and now the images scale correclty, but they are repositioned and only reach the desired position when my zoom level is maximum. Any idea why? Help will be greatly appreciated :) Modified code below: var layer = new MapLayer(); map.AddChild(layer); //Sydney layer.AddChild(new Pin { ImageSource = new BitmapImage(new Uri("pin.png", UriKind.Relative)), MapInstance = map }, new Location(-33.86643, 151.2062), PositionMethod.Center); becomes something like layer.AddChild(new Pin { ImageSource = new BitmapImage(new Uri("pin.png", UriKind.Relative)), MapInstance = map }, new Location(-33.92485, 18.43883), PositionOrigin.BottomCenter); I am assuming it has something to do with a different way in which bing maps anchors its UIelements. Details on that are also very userful. Thank you!

  • how to group data in a list c#

    - by prince23
    hi, i need to group data of a list in c# ex: i have a data like this in a list c# i have a class called information.cs with these properties name,school, parent ex data name school parent kumar fes All manju fes kumar anu frank kumar anitha jss All rohit frank manju anill vijaya manju vani jss kumar soumya jss kumar madhu jss rohit shiva jss rohit vanitha jss anitha anu jss anitha now taking this as an input i wanted the output to be formated with a Hierarchical data when parent is all means it is the topmost level kumar fes All. what i need to do here is i need to create an object[0] and then check in list whether kumar exists as a parent in the list if it exista then add those items as under the object[0] as a parent i need to create one more oject under **manju fes kumar anu frank kumar** what i wanted do here is iterate through the list anD then check the parent level based on name school parent kumar fes All -->obj[0] manju fes kumar -->obj1[0] anu frank kumar -->obj1[1] for obj1-- obj[0] will be parent like this i need to genarte a list or observation class anitha jss All-->obj[1] vanitha jss anitha -->obj1[0] anu jss vanitha -->obj2[0] here obj2[0]--obj1[0]--obj[1] will be an parent like this i need to create a list or an observationclass hope my Question is clear what i am trying ask you people. i wanted to know how i can create an observationclass any help would be really great thanks prince hope my question is clear

  • Constant NSDictionary/NSArray for class methods.

    - by Jeff B
    I am trying to code a global lookup table of sorts. I have game data that is stored in character/string format in a plist, but which needs to be in integer/id format when it is loaded. For instance, in the level data file, a "p" means player. In the game code a player is represented as the integer 1. This let's me do some bitwise operations, etc. I am simplifying greatly here, but trying to get the point across. Also, there is a conversion to coordinates for the sprite on a sprite sheet. Right now this string-integer, integer-string, integer-coordinate, etc. conversion is taking place in several places in code using a case statement. This stinks, of course, and I would rather do it with a dictionary lookup. I created a class called levelInfo, and want to define the dictionary for this conversion, and then class methods to call when I need to do a conversion, or otherwise deal with level data. NSString *levelObjects = @"empty,player,object,thing,doohickey"; int levelIDs[] = [0,1,2,4,8]; // etc etc @implementation LevelInfo +(int) crateIDfromChar: (char) crateChar { int idx = [[crateTypes componentsSeparatedByString:@","] indexOfObject: crateChar]; return levelIDs[idx]; } +(NSString *) crateStringFromID: (int) crateID { return [[crateTypes componentsSeparatedByString:@","] objectAtIndex: crateID]; } @end Is there a better way to do this? It feels wrong to basically build these temporary arrays, or dictionaries, or whatever for each call to do this translation. And I don't know of a way to declare a constant NSArray or NSDictionary. Please, tell me a better way....
