virtual void | setThreadSafeRefUnref (bool threadSafe) |
Set whether to use a mutex to ensure ref() and unref() are thread safe. | |
bool | getThreadSafeRefUnref () const |
Get whether a mutex is used to ensure ref() and unref() are thread safe. | |
OpenThreads::Mutex * | getRefMutex () const |
Get the mutex used to ensure thread safety of ref()/unref(). | |
int | ref () const |
Increment the reference count by one, indicating that this object has another pointer which is referencing it. | |
int | unref () const |
Decrement the reference count by one, indicating that a pointer to this object is referencing it. | |
int | unref_nodelete () const |
Decrement the reference count by one, indicating that a pointer to this object is referencing it. | |
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 |
Remove Observer that is observing this object. |
