|
int | unref () const |
| Decrement the reference count by one, indicating that a pointer to this object is referencing it.
|
int | unref_nodelete () const |

|
int | referenceCount () const |
| Return the number of pointers currently referencing this object.
|
ObserverSet * | getObserverSet () const |
| Get the ObserverSet if one is attached, otherwise return NULL.
|
ObserverSet * | getOrCreateObserverSet () const |
| Get the ObserverSet if one is attached, otherwise create an ObserverSet, attach it, then return this newly created ObserverSet.
|
void | addObserver (Observer *observer) const |
| Add a Observer that is observing this object, notify the Observer when this object gets deleted.
|
void | removeObserver (Observer *observer) const |
