Detailed Description

template<class T>
class ReferenceCountPtr< T >

Templated reference-counting pointer.

Dynamically allocated objects (created via 'new') that are managed via ReferenceCountPtr are automatically destroyed when the last pointer is destroyed. Therefore, a reference-counted object can be shared in different places in the system and will not be leaked or a dangling (invalid) pointer.

A count of the number of pointers to the object is maintained, and when this count reaches zero, the object is destroyed.

In a way, ReferenceCountPtr is a safer version of std::auto_ptr.
