Detailed Description

template<class T>
class Tp::WeakPtr< T >

The WeakPtr class holds a weak reference to an object managed by SharedPtr.

Tp::WeakPtr is useful for example for breaking reference cycles which would result from using a Tp::SharedPtr for both ends of a pair of mutually linked objects to refer to each other.

See Shared Pointer Usage
