public class UnionGraph

extends Graph

implements GraphInterface

An aggregate inmemory Graph, acting much like an SQLGraph.
This keeps a reference to each Graph added but also a central triple
store containing all the triples from all Graphs.

Use add(), remove()

For example (from UnionGraphAddRemoveTest):

Graph g = new
Graph(null,
"http://swordfish.rdfweb.org/people/libby/rdfweb/webwho.xrdf",Util.RDFXML);

g.load();

UnionGraph ug=new UnionGraph();
ug.add(g);

assertEquals(g.size(),ug.size());

ug.remove(g);
