Info

Reference Counting and Ownership > A pointer taking ownership of an reference counted object does not increment its reference count. > This implies that there is no previous owner (in other words, the object has just been created), > or the previous owner gives up ownership (and thus does not decrement the object's reference count). > Usually, the first pointer an object is assigned to after its creation takes ownership. All others do not.
The AutoPtr Class Template > <strong>Poco</strong>::AutoPtr implements a reference counting "smart" pointer. > <strong>Poco</strong>::AutoPtr can be instantiated with any class that supports reference counting. > A class supporting reference counting must > maintain a reference count (initialized to 1 at creation) > implement a method void duplicate() that increments the reference count > implement a method void release() that decrements the reference count and, when it reaches zero, deletes the object
