Member Function Documentation

virtual void Archon::Utilities::BackRefObjectBase::refForwardDestroy (   )  [protected, pure virtual]

This method is called just before the forward reference count drops to zero. The purpose of this method is to take appropriate measures to ensure that all back references to this object held by other objects and or threads will eventually be destroyed. This normally involves two things: Clearing all forward references held by this object to objects that directly or indirectly hold back references to this object, and to send asynchronious termination requests to all threads that hold back references to this object (except if the thread is known to complete relativly fast without being terminated). It is your responsibility to implement this method in such a way that it does not lead to creation of new forward references to this object. You may safely assume that no other than the calling thread will access the object from the point in time where this method is called. Implemented in Archon::X3D::SubSceneNode, and Archon::X3D::NodeBase.
