public abstract class Loader
extends java.lang.Object

This abstract class is a super class for graph loader classes. You can use this guidelines for writing your own Loader class:

• Overwrite the method load.
• Load all Nodes from your source and add them to the Graph object.
• All informations about a indivual you must add to the Node with the method setUserData().
• If you have loaded all Nodes, then add all Edges to the Graph.
