PBoundsLocator

public class PNodeLocator
extends PLocator

PNodeLocator provides an abstraction for locating points on a node. Points are located in the local corrdinate system of the node. The default behavior is to locate the center point of the nodes bounds. The node where the point is located is stored internal to this locator (as an instance varriable). If you want to use the same locator to locate center points on many different nodes you will need to call setNode() before asking for each location.
