class | ACE_Strong_Bound_Ptr |
Assigning or copying instances of an ACE_Strong_Bound_Ptr will automatically increment the reference count of the underlying object. When the last instance of an ACE_Strong_Bound_Ptr that references a particular object is destroyed or overwritten, it will invoke delete on its underlying pointer.
