Package org.apache.jena.graph

Class GraphExtract

  • public class GraphExtract
extends java.lang.Object
    GraphExtract offers a very simple recursive extraction of a subgraph with a specified root in some supergraph. The recursion is terminated by triples that satisfy some supplied boundary condition.
