Detailed Description

Tag dispatch for vector coordinates to be accessed with a static constPointer() function.

"Pointer" access requires that coordinates of a vector object have to be layout contiguously in memory.

Example :

struct MyVector2D
{
  double x;
  double y;
};

namespace math {
  template<> struct VecAccess<MyVector2D>
  {
    static double* pointer(MyVector2D& vec) // Optional: required only for mutating algorithms
    { return &vec.x; }

    static const double* pointer(const MyVector2D& vec)
    { return &vec.x; }
  };
}
