static-variables

I am attempting to add a variable to a class that holds instances to the class. The following is a shortened version of my code. class Classy : def __init__(self) : self.hi = "HI!" # "CLASSIES" variable holds instances of class "Classy" CLASSIES = [] for i in xrange(0,4) : CLASSIES.append(Classy()) Upon running the code, I get the following error. Traceback (most recent call last): File "classy.py", line 6, in Classy CLASSIES.append(Classy()) NameError: name 'Classy' is not defined Is there another way to add instances of a class to a class/static variable within that class? The class body is

In order to make my code testable, I have created a lazy initializer; this way in my unit test, I can mock any object I want before the getter gets called. When it comes to class methods, though, my class method doesn't have access to the properties I have defined. Is there any way to make the properties accessible by my class method? If not, is there any way to create static variables that are also accessible outside of this class, i.e., accessible by my unit test class? @implementation @synthesize webService; + (void)doSomething { self.webService.url = @"some url"; [self.webService start]; /

I have a problem in sharing static variable between different threads in PHP. In simple words I want to 1. Write a static variable in one thread 2. Read it in other thread and do the required process and clean it. For testing above requirement I have written below PHP script. <?php class ThreadDemo1 extends Thread { private $mode; //to run 2 threads in different modes private static $test; //Static variable shared between threads //Instance is created with different mode function __construct($mode) { $this->mode = $mode; } //Set the static variable using mode 'w' function w_mode() { echo

Possible Duplicate: Static variable How to access a static variable from another file in C? As a Static variable has a file scope, I think there is no way we can access it outside a file. But still I feel there might be some trick or way to do the same. I don't think there is a easy way. If you can change the file with the static variable you can do something like: static int hiddenVar; // The static var you want to get at // A new function you write int * getHiddenVar() { return &hiddenVar; } But of course if you can change the file, you would just drop the static keyword. Also, I doubt this

Overriding static field in derived class causes error TS2417: Build:Class static side 'typeof TDerived' incorrectly extends base class static side 'typeof TBase'. Is this a legit error case? class TBase { private static s_field = 'something'; public constructor() {} } class TDerived extends TBase { private static s_field = 'something else'; // commenting this line fixes error public constructor() { super(); } } How should i deal with static fields then? The only workaround right now would be to prepend class name to every static field name which is an exceptionally ugly solution. private

I'm writing a simple android application which is basically a modification of the fragments demo available in the android documentation. In the app, there is a file called Ipsum.java which has a static ArrayList of Strings called Headlines. In the onCreate() method of the main activity, I have the following code which adds some elements into the array list. if (savedInstanceState == null){ Ipsum.Headlines.add("String 1 "); Ipsum.Headlines.add("String 2"); } savedInstanceState is a Bundle that the system passes to the method, if the app is being resumed from some inactive state. The logic is
