Robert Osfield	530c947c94	Added an InitGlobalMutexes to enforce early construction and hence late destruction of singleton mutexes.	2010-02-19 09:02:24 +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	ab66740fb0	Added new setNodePathTo() method	2010-02-18 09:00:37 +00:00
Robert Osfield	4a567d9954	Introduced new osg::ObserverNodePath class that robustly manages a NodePath in a thread safe manner, ... making it easier for users to track a NodePath even when nodes in the path get deleted.	2010-02-15 20:14:32 +00:00
