Class PseudoGraphJenaGraph

java.lang.Object
org.aksw.commons.jena.jgrapht.PseudoGraphJenaGraph
All Implemented Interfaces:
org.jgrapht.Graph<org.apache.jena.graph.Node,org.apache.jena.graph.Triple>
public class PseudoGraphJenaGraph extends Object implements org.jgrapht.Graph<org.apache.jena.graph.Node,org.apache.jena.graph.Triple>
Wrapper for exposing a Jena graph as a JGraphT directed pseudo graph. Note: All graph lookups are done via a .find() method that does additional filtering for supporting variables as vertices.
