Class XMLGraph

java.lang.Object
  org.wilmascope.file.XMLGraph

public class XMLGraph
extends java.lang.Object

Wrapper round the XML DOM calls for the WilmaGraph file. XMLGraph wraps the root of the DOM Document. XMLGraphElement is a wrapper for dom elements and is inherited by: Node, Edge, LayoutEngineType, ViewType and Cluster subclasses Node. Each of these has two constructors... one for writing to a new file... in which everything is created from scratch, and one for reading where the object is created around the Element.
