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 theQuadPredicate
and match ifQuadPredicate.test(Object, Object, Object, Object)
returns true.Important: This is slower and less scalable than
TriConstraintStream.join(UniConstraintStream, QuadJoiner)
with a properQuadJoiner
predicate (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:QuadConstraintStream
As 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
SafeVarargs
annotation because it's an interface method. Therefore, there are overloaded methods with up to 4PentaJoiner
parameters.- Specified by:
ifExists
in 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
PentaJoiner
s 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:QuadConstraintStream
As 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
SafeVarargs
annotation because it's an interface method. Therefore, there are overloaded methods with up to 4PentaJoiner
parameters.- Specified by:

in 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
