getCardinality
public int getCardinality()
- Specified by:

-
filter
public QuadConstraintStream<A,B,C,D> filter(QuadPredicate<A,B,C,D> predicate)
Description copied from interface:QuadConstraintStreamExhaustively test each tuple of facts against theQuadPredicateand match ifQuadPredicate.test(Object, Object, Object, Object)returns true.Important: This is slower and less scalable than
TriConstraintStream.join(UniConstraintStream, QuadJoiner)with a properQuadJoinerpredicate (such asJoiners.equal(TriFunction, Function), because the latter applies hashing and/or indexing, so it doesn't create every combination just to filter it out.
-
ifExists
@SafeVarargs public final <E> QuadConstraintStream<A,B,C,D> ifExists(Class<E> otherClass, PentaJoiner<A,B,C,D,E>... joiners)
Description copied from interface:QuadConstraintStreamAs defined byQuadConstraintStream.ifExists(Class, PentaJoiner). For performance reasons, indexing joiners must be placed before filtering joiners.This method causes Unchecked generics array creation for varargs parameter warnings, but we can't fix it with a
SafeVarargsannotation because it's an interface method. Therefore, there are overloaded methods with up to 4PentaJoinerparameters.- Specified by:
ifExistsin interfaceQuadConstraintStream<Solution_,A,B,C>- Type Parameters:
E- the type of the fifth matched fact- Parameters:
otherClass- never nulljoiners- never null- Returns:
- never null, a stream that matches every tuple of A, B, C and D where E exists for which the
PentaJoiners are true
-
ifNotExists
@SafeVarargs public final <E> QuadConstraintStream<A,B,C,D> ifNotExists(Class<E> otherClass, PentaJoiner<A,B,C,D,E>... joiners)
Description copied from interface:QuadConstraintStreamAs defined byQuadConstraintStream.ifNotExists(Class, PentaJoiner). For performance reasons, indexing joiners must be placed before filtering joiners.This method causes Unchecked generics array creation for varargs parameter warnings, but we can't fix it with a
SafeVarargsannotation because it's an interface method. Therefore, there are overloaded methods with up to 4PentaJoinerparameters.- Specified by:
ifNotExistsin interfaceQuadConstraintStream<Solution_,A,B,C>- Type Parameters:
E- the type of the fifth matched fact- Parameters:
otherClass- never nulljoiners- never null- Returns:
- never null, a stream that matches every tuple of A, B, C and D where E does not exist for which the
PentaJoiners are true
-
