DroolsAbstractTriConstraintStream

Method Detail

filter

public TriConstraintStream<A,B,C> filter(TriPredicate<A,B,C> predicate)

Description copied from interface: TriConstraintStream

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

Important: This is slower and less scalable than BiConstraintStream.join(UniConstraintStream, TriJoiner) with a proper TriJoiner predicate (such as Joiners.equal(BiFunction, 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 TriConstraintStream<A,B,C>

Parameters:

predicate - never null

Returns:

never null

join

public <D> QuadConstraintStream<A,B,C,D> join(UniConstraintStream<D> otherStream,
                                              QuadJoiner<A,B,C,D> joiner)

Description copied from interface: TriConstraintStream

Create a new QuadConstraintStream for every combination of [A, B] and C for which the QuadJoiner is true (for the properties it extracts from all facts).

Important: This is faster and more scalable than a join followed by a filter, because it applies hashing and/or indexing on the properties, so it doesn't create nor checks every combination of [A, B, C] and D.

Specified by:

join in interface TriConstraintStream<A,B,C>

Type Parameters:

D - the type of the fourth matched fact

Parameters:

otherStream - never null

joiner - never null

Returns:

a stream that matches every combination of [A, B, C] and D for which the QuadJoiner is true
