Robert Osfield	b1001c2a9c	Moved implementation of Observer destructor and constructor from header into .cpp to avoid possible issues with imports/exports under Windows build.	2010-02-19 20:18:48 +00:00
Robert Osfield	b5c5ae7185	Added newline.	2010-02-18 22:53:15 +00:00
Robert Osfield	b09757bdb8	Refactored the osg::Referenced observerset code so that it now uses a dedicated ObserverSet class, ... which utilises a global recursive mutex that is dedicated to manage Observer and ObserverSet. The new global mutex for observers avoids problems with deadlocks that were occurring previously when an osg::Refenced object was being deleted at the same time as on osg::ObserverNodePath.	2010-02-18 21:21:12 +00:00
Robert Osfield	644b2e15d1	Refactored the osg::Observer to introduce a new bool Observer::objectUnreferenced(void*) method that adds ... the extra capability of making it possible for Observers to assume ownership of a object that would otherwsie be deleted. Added a thread safe ref_ptr<T> observer_ptr<T>::lock() method for robust access to an observed object. This makes observer_ptr<> more equivilant to boosts weak_ptr.	2010-02-15 20:12:53 +00:00
