- 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. More...
 
 Referenced (const Referenced &)
 
Referencedoperator= (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. More...
 
bool getThreadSafeRefUnref () const
 Get whether a mutex is used to ensure ref() and unref() are thread safe. More...
 
OpenThreads::MutexgetRefMutex () const
 Get the mutex used to ensure thread safety of ref()/unref(). More...
 
int ref () const
 Increment the reference count by one, indicating that this object has another pointer which is referencing it. More...
 
int unref () const
 Decrement the reference count by one, indicating that a pointer to this object is no longer referencing it. More...
 
int unref_nodelete () const
 Decrement the reference count by one, indicating that a pointer to this object is no longer referencing it. More...
 
int referenceCount () const
 Return the number of pointers currently referencing this object. More...
 
ObserverSetgetObserverSet () const
 Get the ObserverSet if one is attached, otherwise return NULL. More...
 
ObserverSetgetOrCreateObserverSet () const
 Get the ObserverSet if one is attached, otherwise create an ObserverSet, attach it, then return this newly created ObserverSet. More...
 
void addObserver (Observer *observer) const
 Add a Observer that is observing this object, notify the Observer when this object gets deleted. More...
 
void removeObserver (Observer *observer) const
 Remove Observer that is observing this object. More...
