pure virtual

◆ addNodeRef()

void SGNODE::addNodeRef ( SGNODE * aNode )

Function addNodeRef adds a pointer to a node which references, but does not own, this node.

Such back-pointers are required to ensure that invalidated references are removed when a node is deleted

Parameters

aNode is the node holding a reference to this object
