Method Detail

filter

public QuadConstraintStream<A,B,C,D> filter(QuadPredicate<A,B,C,D> predicate)

Description copied from interface: QuadConstraintStream

Exhaustively test each tuple of facts against the QuadPredicate and match if QuadPredicate.test(Object, Object, Object, Object) returns true.

Important: This is slower and less scalable than TriConstraintStream.join(UniConstraintStream, QuadJoiner) with a proper QuadJoiner predicate (such as Joiners.equal(TriFunction, Function), because the latter applies hashing and/or indexing, so it doesn't create every combination just to filter it out.

Specified by:

filter in interface QuadConstraintStream<A,B,C,D>

Parameters:

predicate - never null

Returns:

never null
