Interface SAINodeFactory

public interface SAINodeFactory

SAINodeFactory is the intermediary intended to break what would be two dependency loops in the SAI implementation--between EventIn*NodeWrapper and SimpleWrappingNode and between SimpleWrappingNode and EventOut*Node Wrapper.

Given a VRMLNodeType or X3DNode, this class can produce or locate the corresponding instance. Whether the instance returned is unique or simply equivalent between subsequent calls is implementation dependent.
