C++ const static member array initialization -

i have class foo member variable bar big array of dynamic_bitset. make variable bar static sake of memory, const. value of bar stored in predefined file. should put code reading file , initializing bar?

madsciencedreams's solution work, can more simply:

in header

class {      static const vector<dynamic_bitset> s; public:      // ... }; 

in implementation file

vector<dynamic_bitset> loadbitsets() {     //...     return something; }  const vector<dynamic_bitset> a::s(loadbitsets()); 

the move constructor should used automatically.
