Method Details

getJustificationMapping

protected BiFunction<A,Score_,ConstraintJustification> getJustificationMapping()

Specified by:

getJustificationMapping in class AbstractConstraintBuilder<Score_ extends Score<Score_>>

justifyWith

public <ConstraintJustification_ extends ConstraintJustification>
@NonNull UniConstraintBuilder<A,Score_> justifyWith(@NonNull BiFunction<A,Score_,ConstraintJustification_> justificationMapping)

Description copied from interface: UniConstraintBuilder

Sets a custom function to apply on a constraint match to justify it. That function must not return a Collection, else IllegalStateException will be thrown during score calculation.

Specified by:

justifyWith in interface UniConstraintBuilder<A,Score_ extends Score<Score_>>

Returns:

this

getIndictedObjectsMapping

protected Function<A,Collection<Object>> getIndictedObjectsMapping()

Specified by:

getIndictedObjectsMapping in class AbstractConstraintBuilder<Score_ extends Score<Score_>>

indictWith

public @NonNull UniConstraintBuilder<A,Score_> indictWith(@NonNull Function<A,Collection<Object>> indictedObjectsMapping)

Description copied from interface: UniConstraintBuilder

Sets a custom function to mark any object returned by it as responsible for causing the constraint to match. Each object in the collection returned by this function will become an Indictment and be available as a key in ScoreExplanation.getIndictmentMap().

Specified by:

indictWith in interface UniConstraintBuilder<A,Score_ extends Score<Score_>>

Returns:

this
