Method Detail

guaranteesDistinct

boolean guaranteesDistinct()

This method will return true if the constraint stream is guaranteed to only produce distinct tuples. See distinct() for details.

Returns:

true if the guarantee of distinct tuples is provided

join

default <B> BiConstraintStream<A,B> join(UniConstraintStream<B> otherStream,
                                               BiJoiner<A,B>... joiners)

Description copied from interface: UniConstraintStream

As defined by UniConstraintStream.join(UniConstraintStream, BiJoiner). If multiple BiJoiners are provided, for performance reasons, the 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 4 BiJoiner parameters.

Specified by:

join in interface UniConstraintStream<A>

Type Parameters:

B - the type of the second matched fact

Parameters:

otherStream - never null

joiners - never null

Returns:

never null, a stream that matches every combination of A and B for which all the joiners are true

distinct

default UniConstraintStream<A> distinct()

Description copied from interface: UniConstraintStream

Transforms the stream in such a way that all the tuples going through it are distinct. (No two tuples will equal.)

By default, tuples going through a constraint stream are distinct. However, operations such as UniConstraintStream.map(Function) may create a stream which breaks that promise. By calling this method on such a stream, duplicate copies of the same tuple will be omitted at a performance cost.

Specified by:

distinct in interface UniConstraintStream<A>

Returns:

never null

penalize

default Constraint penalize(String constraintPackage,
                            String constraintName,

                            ToIntFunction<A> matchWeigher)

Description copied from interface: UniConstraintStream

As defined by UniConstraintStream.penalize(String, Score, ToIntFunction).

Specified by:

penalize in interface UniConstraintStream<A>

Parameters:

constraintPackage - never null

constraintName - never null

constraintWeight - never null

matchWeigher - never null
