Public Member Functions inherited from osg::Referenced
	Referenced ()
	Referenced (bool threadSafeRefUnref)

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. More...
