Detailed Description

template<class T>
class GCpp::weak_ptr< T >

Weak pointer to managed objects.

Allows accessing managed instances without being recognized by the collectors. A weak pointer validates against the block of memory it points to, not the strong pointer it's been created from. Be careful to either stop the collector or having at least one strong (gc_ptr) pointer referencing the same object(s) while working with weak pointers.
