Yes, that's why an interface defining equals so that instances of different implementations can be equals must also define hashCode() as this is done by: http://incubator.apache.org/clerezza/mvn-site/org.apache.clerezza.rdf.core/apidocs/org/apache/clerezza/rdf/core/Graph.html#hashCode%28%29 > The converse is not necessarily true. > Cannot be as there are more than 2^32 graphs.
