All Implemented Interfaces:

Graph, GraphWithPerform

public class Intersection
extends Dyadic
implements Graph

The dynamic intersection of two graphs L and R. add() affects both L and R, whereas delete() affects L only.

Method Details

performAdd

public void performAdd(Triple t)

Description copied from class: GraphBase

Add a triple to the triple store. The default implementation throws an AddDeniedException; subclasses must override if they want to be able to add triples.

Specified by:

performAdd in interface GraphWithPerform

Overrides:

performAdd in class GraphBase

performDelete

public void performDelete(Triple t)

Description copied from class: GraphBase

Remove a triple from the triple store. The default implementation throws a DeleteDeniedException; subclasses must override if they want to be able to remove triples.

Specified by:

performDelete in interface GraphWithPerform

Overrides:

performDelete in class GraphBase
