All Implemented Interfaces:

AttributeChangeListener, ChangeBoundaryListener, EdgeChangeListener, Graph, Lockable

Direct Known Subclasses:

AttributeOverwritingFilter

public abstract class GraphFilter
extends GraphBase
implements ChangeBoundaryListener, AttributeChangeListener, EdgeChangeListener

A GraphFilter is a Graph which has another graph as source and filters the data of the source graph. Filtering may include modification of structure and attributes. The implementations of Graph methods in this class just forward their invocation to the corresponding methods of the source graph.
