Description copied from interface: UniConstraintStream

As defined by UniConstraintStream.join(Class, BiJoiner). 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:

Parameters:

otherClass - never null

joiners - never null

Returns:

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

Applies a negative Score impact, subtracting the constraintWeight multiplied by the match weight, and returns a builder to apply optional constraint properties.

The constraintWeight specified here can be overridden using ConstraintWeightOverrides on the PlanningSolution-annotated class

For non-int Score types use UniConstraintStream.penalizeLong(Score, ToLongFunction) or UniConstraintStream.penalizeBigDecimal(Score, Function) instead.

Specified by:
