com.hp.hpl.jena.rdf.model.InfModel.listStatements()
Find all the statements matching a pattern.
Return an iterator over all the statements in a model that match a pattern. The statements selected are those whose subject matches the subject argument, whose predicate matches the predicate argument and whose object matchesthe object argument. If an argument is null it matches anything.

The s/p/o terms may refer to resources which are temporarily defined in the "posit" model. This allows one, for example, to query what resources are of type CE where CE is a class expression rather than a named class - put CE in the posit arg.
@return an iterator over the subjects @param subject The subject sought @param predicate The predicate sought @param object The value sought
