Initialisation of static vector

Question

I wonder if there is the \"nicer\" way of initialising a static vector than below?

class Foo
{
    static std::vector MyVector;
    Foo()
    {
           


        

Answer 1

Typically, I have a class for constructing containers that I use (like this one from boost), such that you can do:

const list primes = list_of(2)(3)(5)(7)(11);

That way, you can make the static const as well, to avoid accidental modifications.

For a static, you could define this in the .cc file:

// Foo.h

class Foo {
  static const vector something;
}

// Foo.cc

const vector Foo::something = list_of(3)(5);

In C++Ox, we'll have a language mechanism to do this, using initializer lists, so you could just do:

const vector primes({2, 3, 5, 7, 11});
