Detailed Description

template<typename T>
class Handle< T >

Handle class template - a simplified version of boost::intrusive_ptr.

_____________________________________________________________________________

It's a smart pointer for objects with "built-in" reference count. Such implemetation makes the smallest possible smart pointer - its size is equivalent to just a single raw pointer.
