Pointer to object policy for copying map elements.
Defines a copy method to properly handle pointers to objects (assumed) when copying the complete CollectorMap. This implementation assumes the copy constructor properly handles the creation of a new element from a different one.
This policy assumes the assignment operator handles the proper copying of each element T* in the collection.
This employs an intersting technique of redirection. Because the type T is actually T*, the templated allocate() method exists to get down to the T class base level. Looks strange but it works.
|T Isis::PointerCopy< T >::copy||(||const T &||src||)|| const
Allocate new object using copy construtor and new pointer.
This copy method takes a pointer to a pointer (T is actually a T*) and allocates a new object using the copy constructor.
