Class GraphDifferencer

java.lang.Object
org.fcrepo.kernel.api.utils.GraphDifferencer
public class GraphDifferencer extends Object
A wrapping Stream that calculates two differences between a Graph A and a source Stream B. The differences are (A - (A ∩ B)) and (B - (A ∩ B)). The ordinary output of this stream is (B - (A ∩ B)), and after exhaustion, sets containing (A - (A ∩ B)) and (A ∩ B) are available.
