All Implemented Interfaces:

NodeCursorInterface

public class DomGraphLayoutCursor
extends DomGraphNodeCursor

A class to determine the positions of nodes in a graph that is a tree, relative to their direct parents. These positions are stored in a given layout algorithm and converted later on by a DomGraphDrawingCursor. A subclass of DomGraphNodeCursor.
