Detailed Description

template<typename T>
struct Isis::PointerCopy< T >

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.
