Interface GenericNodeRealizer.LayerHandler

Enclosing class:

GenericNodeRealizer

public static interface GenericNodeRealizer.LayerHandler

This interface is used by GenericNodeRealizer to delegate the work of the GenericNodeRealizer.getLayer() and the GenericNodeRealizer.setLayer(byte) methods to. Classes implementing this interface should query the given context NodeRealizer for the necessary information each time the methods are called since they will be shared instances for multiple GenericNodeRealizer instances.

Method Summary

byte	getLayer(NodeRealizer context) Returns the logical graphical layer for this realizer.
void	setLayer(NodeRealizer context, byte l) Sets the logical graphical layer for this realizer.
