public class ProxyShapeNodeRealizer

extends ShapeNodeRealizer

A ShapeNodeRealizer that can act as a proxy to another internally used realizer. Also, this class can maintain a list of realizers, that will be copied, saved and restored when performing these operations on this class. Usually the held realizers define the set of possible delegation targets of this class.
