Constructor Summary
ConstructorsConstructorDescriptionMemTripleIterator(MemStatementList statementList, MemResource subject, MemIRI predicate, MemValue object, int snapshot) Creates a new MemTripleIterator that will iterate over the triples contained in the supplied MemStatementList searching for triples that occur as either subject or object in those statements, and which match the specified pattern of subject, predicate, object. -
