Public Member Functions inherited from osg::Referenced
	Referenced ()
	Referenced (bool threadSafeRefUnref)
	Deprecated, Referenced is now always uses thread safe ref/unref, use default Referenced() constructor instead.
	Referenced (const Referenced &)
Referenced &	operator= (const Referenced &)
virtual void	setThreadSafeRefUnref (bool)
	Deprecated, Referenced is always theadsafe so there method now has no effect and does not need to be called.
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 no longer referencing it.
int	unref_nodelete () const
	Decrement the reference count by one, indicating that a pointer to this object is no longer 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.
