initialize a private static std::list

[umesh_at_dani]

how/where to initialize a static private std::list member ?

[mike_2000_17]

Where: in the source file (not in the header file).
How: like this:

// in my_class.h:

#include <list>

class MyClass {
  private:
    static std::list<int> privateList;
};


// in my_class.cpp:

#include "my_class.h"

std::list<int> MyClass::privateList = std::list<int>();

Or with whatever else you want to initialize it with.

[rubberman]

"Or with whatever else you want to initialize it with."

Or nothing at all, and let the initializer for the translation unit call the default constructor, as in:

// myclass.cpp
#include "myclass.h"

std::list<int> MyClass::privateList;

.
.
.

mike_2000_17's approach is equally valid (perhaps more so), and will force it to be initialized, even if there is no other access to the object in this translation unit (.cpp file).
