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
Subsequent operations on those statements may modify this model.@return an iterator over all statements in the model.
