org.apache.clerezza.rdf.core.TripleCollection
A set of triples (as it doesn't allow duplicates), it does however not extend {@link java.util.Set} as it doesn't inherit itsspecification for hashCode() and equals. It is possible to add GraphListener to listen for modifications in the triples. @author reto
