I've completed most of the game I'm attempting to make and throughout the project I've created one particular Activity which also calls a SurfaceView and a Thread. I put an update() method in each of the 3 classes so they each know where the other ones are everytime something changes. Apparently, the only way to do something like this ...
I'm writing Python scripts for Blender for a project, but I'm pretty new to the language. Something I am confused about is the usage of static variables. Here is the piece of code I am currently working on: class panelToggle(bpy.types.Operator): active = False def invoke(self, context, event): self.active = not self.act...
I'd like to create a RegEx Pattern statically, but I think I have the syntax wrong? static { Pattern noHREF = Pattern.compile("<a.+?>", Pattern.CASE_INSENSITIVE); } public static String getStringWithHREFsRemoved(String html) { Matcher m = noHREF.matcher(html); etc..... ...
In a pre-WCF .NET (C#) web service, I have an expensive IDisposable resource that I'm holding a static (actually ThreadStatic) reference to. (Internally it holds a SqlConnection.) How can I insure that this is disposed when the app pool refreshes, should I simply suppress the FxCop warning and not worry about it, or is there a third opti...
I guess there may not be any difference but personal preference, but when reading various PHP code I come across both ways to access the methods class. What is the difference: class Myclass { public static $foo; public static function myMethod () { // between: self::$foo; // and MyClass::$fo...
Is there a way to reset variables declared as static within a function? The goal is to make sure that the function is not called with lingering values from an unrelated call. For example, I have a function opearting on columns of a matrix. int foo(matrix *A, int colnum, int rownum){ static int whichColumn; static int *v; //vector of l...
Given the following: module MyModule = let myObj = new MyObj() type MyType() = static let myObj_ = new MyObj() static member myObj = myObj_ ... are MyModule.myObj and MyType.myObj functionally (no pun intended) equivalent? Whenever I call MyModule.myObj or MyType.myObj, I don't want the code to actually create a new obje...
Hi, I do have a class which looks like below: //.h file class __declspec(dllimport) MyClass { public: //stuff private: static int myInt; }; // .cpp file int MyClass::myInt = 0; I get the following compile error: error C2491: 'MyClass::myInt' : definition of dllimport static data member not allowed what should I d...
Hi all, I have problem concerning translations in qt. All translations in my porject work fine, but one, which is in a static variable of a class. Corresponding part of code looks as follows The header file is similar to this: typedef struct { int type; QString problematicString; } info; MyClass::QObject_Descend...
I have a manager as Spring wired bean. I believe every bean defined for spring by default is wired as singleton. I have some methods in this bean which I need to synchronize. How should I be doing that then -- void zzz() { synchronized (this) { ... } } or void zzz() { synchronized (MyClass.class) { ... } } ? ...
class Foo { public: static const int kType = 42; }; void Func() { Foo *bar = NULL; int x = bar->kType; putc(x, stderr); } Is this defined behavior? I read through the C++ standard but couldn't find anything about accessing a static const value like this... I've examined the assembly produced by GCC 4.2, Clang++, and Visual Studio ...
Quick question - When are static fields initialized? If I never instantiate a class, but I access a static field, are ALL the static blocks and private static methods used to instantiate private static fields called (in order) at that instant? What if I call a static method? Does it also run all the static blocks? Before the method? ...
I have an application that has several classes used for storing application-wide settings (locations of resources, user settings, and such). Right now these classes are just full of static fields and methods, but I never instantiate them. Someone suggested I make them Singletons, What's the case for/against? ...
I've created a static class in Flash which works as the inventory delegate for this game. Flash though keeps giving me this error: ArgumentError: Error #1063: Argument count mismatch on Inventory(). Expected 1, got 0. at flash.display::Sprite/constructChildren() at flash.display::Sprite() at flash.display::MovieClip(...
So I'm using static class members so I can share data between class methods and static methods of the same class (there will only be 1 instantiation of the class). I understand this fine, but I'm just wondering when the static members get initialized? Is it on import? On the first use of the class? Because I'm going to be calling the sta...
Hi! I have a utility class which has only static methods, so it is not inheriting from NSObject (No need right?) There are no warnings at all when compiling. The problem comes when running on the iPhone simulator. It crashes with warning "does not implement methodSignatureForSelector: -- trouble ahead" Well, I like that "trouble ahead...
Possible Duplicate: Are C# auto-implemented static properties thread-safe? In the following example class static class Shared { public static string[] Values { get; set; } } many reader threads read the Values string array periodically, while from time to time a single writer will replace the whole array with a new valu...
I know static is an overloaded keyword in C. Here, I'm only interested in its use as a keyword to enforce internal linkage. If you have a global variable declared in a .c file, what is the difference between using static and not using static? Either way, no other .c file has access to the variable, so the variable is basically "priva...
I get this error: Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class.

Hi, I cannot seem to get the syntax quite right for this: I have a Jython script and a Java application loaded into the same JVM (for testing). I need to access a particular part of the application through a Singleton class from the Jython script. How do I do this? Thanks EDIT: The set up is for automated testing, so assume that t...
