How to explicitly instantiate a template for all members of MPL vector in C++?

Question

Consider the following header file:

// Foo.h
class Foo {
    public: 
        template 
        void read(T& value);
};

I am not sure if this is the solution to your problem, but maybe you can do with a template specialization.

New header:

// Foo.h

template < typename T >
struct RealRead;

class Foo {
    public: 
        template 
        void read(T& value);
};

template 
void Foo::read(T& value)
{
  RealRead< T >::read( value );
}

New source :

template < >
struct RealRead< int >
{
  static void read( int & v )
  {
    // do read
  }
};
template < >
struct RealRead< float >
{
  static void read( float & v )
  {
    // do read
  }
};

//etc

// explicitly instantiate templates
template struct RealRead< int >;
template struct RealRead< float >;
