class-members

I would like to create a class in Python that manages above all static members. These members should be initiliazed during definition of the class already. Due to the fact that there will be the requirement to reinitialize the static members later on I would put this code into a classmethod. My question: How can I call this classmethod from inside the class? class Test(): # static member x = None # HERE I WOULD LOVE TO CALL SOMEHOW static_init! # initialize static member in classmethod, so that it can be #reinitialized later on again @classmethod def static_init(cls): cls.x = 10 Any help is

I've got a class that has a couple of objects as member variables. I don't want the constructors for these members to be called when declared, so I'm trying to hang onto a pointer to the object explicitly. I have no idea what I'm doing. o_O On StackOverflow, I seem to be able to find other examples of object member variables, but usually the constructor is called immediately, like this: class MyClass { public: MyClass(int n); private: AnotherClass another(100); // this constructs AnotherClass right away! }; But I want the MyClass constructor to call the AnotherClass constructor. Here's what my

The following code doesn't compile with gcc, but does with Visual Studio: template <typename T> class A { public: T foo; }; template <typename T> class B: public A <T> { public: void bar() { cout << foo << endl; } }; I get the error: test.cpp: In member function ‘void B::bar()’: test.cpp:11: error: ‘foo’ was not declared in this scope But it should be! If I change bar to void bar() { cout << this->foo << endl; } then it does compile, but I don't think I have to do this. Is there something in the official specs of C++ that GCC is following here, or is it just a quirk? This changed in gcc-3.4 .

Before C++11, we could only perform in-class initialization on static const members of integral or enumeration type. Stroustrup discusses this in his C++ FAQ , giving the following example: class Y { const int c3 = 7; // error: not static static int c4 = 7; // error: not const static const float c5 = 7; // error: not integral }; And the following reasoning: So why do these inconvenient restrictions exist? A class is typically declared in a header file and a header file is typically included into many translation units. However, to avoid complicated linker rules, C++ requires that every object
