Examples of org.neo4j.graphdb.Path

org.neo4j.graphdb.Path
Represents a path in the graph. A path starts with a node followed by pairs of {@link Relationship} and {@link Node} objects. The shortest pathis of length 0. Such a path contains only one node and no relationships. During a traversal {@link Path} instances are emitted where the currentposition of the traverser is represented by each such path. The current node in such a traversal is reached via {@link Path#endNode()}.

    
    @Test
    public void testSingle()
    {
        PathFinder<Path> finder = newFinder();
        Path path = finder.findSinglePath( graph.getNode( "SOURCE" ), graph.getNode( "TARGET" ) );
        assertNotNull( path );
        assertPathDef( path, "SOURCE", "z", "9", "0", "TARGET" ); 
    }
