Constructor Summary

GraphExtract(TripleBoundary b)

Method Summary

Graph	extract(Node node, Graph graph) Answer a new graph which is the reachable subgraph from node in graph with the terminating condition given by the TripleBoundary passed to the constructor.
Graph	extractInto(Graph toUpdate, Node root, Graph extractFrom) Answer the graph toUpdate augmented with the sub-graph of extractFrom reachable from root bounded by this instance's TripleBoundary.
