Basically you run around and tries to collect all the item coins, the monsters tries to prevent you and you can shoot them down with the bullets that you collect. Very simple. The question is, i have added the monsters,...
Is there any way to stop a running loop inside another method or insert a break statement dynamically in C#? Thanks Edit : I want to be able to dynamically intercept the method and insert a break to stop the loop when an event gets triggered in another function.I have several instances of the class and I want to stop the loop in each i...
I have an old function that is called many times in my application. I would like to update it a bit, which involves adding some new arguments. When I wrote the function, I did not understand the benefits has making a hash the only parameter (mentioned here: http://www.skorks.com/2009/08/more-advanced-ruby-method-arguments-hashes-and-bl...
Basically what I want to do is get a start button to initiate a method running in another class and acting on another object. My code for the listener: button1a.addActionListener(new ActionListener() { public void actionPerformed (ActionEvent event) { // Figure out how to make this work //sim.runCastleCrash(); } }...
If I have a java class which is package-private (declared with "class", not "public class"), there is really no difference if the methods inside are declared public or protected or package-private, right? So which should I use, or when should I use which? I'm a bit confused. ...

I'm writing an interface that requires classes to implement a clone() method. My naive approach to this went along the following lines: public interface ISolvableGame { function clone():ISolvableGame; //... } elsewhere: public class MyGame implements ISolvableGame { public function clone():MyGame { // ... } } ...
Hello, I have the following situation in code, which I suspect may be a bit dodgey: I have a class: abstract class DataAccessBase<T> : IDataAccess where T : AnotherAbstractClass This class DataAccessBase also has a static factory method which creates instances of derived classes of itself using an enum value in a which statement to d...
class MetaData { public String version; public String compression; } I make a MetaData object, pass it into a method, and fill the version and compression fields from within the method. And I want these changes to exist outside of the lifetime of the method. In C++ I think I added a & or something to pass the object itself and ...

I've been having a discussion with my coworkers as to whether to prefix overridden methods with the virtual keyword, or only at the originating base class. I tend to prefix all virtual methods (that is, methods involving a vtable lookup) with the virtual keyword. My rationale is threefold: Given that C++ lacks an override keyword, the...
I want to write a debug function or method that will help print useful information. When it is called, I need: the memory address of the calling object (if called by an object) the method signature of the caller (or the name of the method), or the name of the function the class name that owns that method or function Is it possible to...
I understand that static method inheritance is not supported in C#. I have also read a number of discussions (including here) in which developers claim a need for this functionality, to which the typical response is "if you need static member inheritance, there's a flaw in your design". OK, given that OOP doesn't want me to even think a...
I am working with a Python class, and I don't have write access to its declaration. How can I attach a custom method (such as __str__) to the objects created from that class without modifying the class declaration? EDIT: Thank you for all your answers. I tried them all but they haven't resolved my problem. Here is a minimal example tha...
I have a silly, little class "FileSystemSize" which can be used both as an object and also via public, static methods. The output is similar, but not identical in each case. The class was intially static, but I added the possibility to initialize it as an object to allow extending with new "convenience methods" in future versions, witho...
If I have function names stored as strings in a Hashtable. Is there a way to access the functions via the stored strings? EDIT I'm afraid the platform that i'm working on CLDC1.1/MIDP2.0 does not support Reflection. Any workaround possible? ...
Does anybody know how I can write "cardImage1.BorderStyle = BorderStyle.Fixed3D;" without having to explicitly declare "cardImage1"? I'm trying to put it into a method so that I don't need to write the code to toggle between two Border Styles when a Picture Box is clicked, for every single single picture box (there are 52!) e.g. for e...
