BavetConstraintFactory

public BavetConstraintFactory(org.optaplanner.core.impl.domain.solution.descriptor.SolutionDescriptor<Solution_> solutionDescriptor)

Method Details

share

public <Stream_ extends BavetAbstractConstraintStream<Solution_>>
Stream_ share(Stream_ stream)

share

public <Stream_ extends BavetAbstractConstraintStream<Solution_>>
Stream_ share(Stream_ stream,
 Consumer<Stream_> consumer)

Enables node sharing. If a constraint already exists in this factory, it replaces it by the old copy. BavetAbstractConstraintStream implement equals/hashcode ignoring child streams.

BavetConstraintSessionFactory.buildSession(boolean, Object) relies on this occurring for all streams.

This must be called before the stream receives child streams.

Type Parameters:

Stream_ - the BavetAbstractConstraintStream subclass

Parameters:

stream - never null

consumer - never null

Returns:

never null

forEachIncludingNullVars

public <A>
org.optaplanner.core.api.score.stream.uni.UniConstraintStream<A> forEachIncludingNullVars(Class<A> sourceClass)

fromUnfiltered

public <A>

getSolutionDescriptor

public org.optaplanner.core.impl.domain.solution.descriptor.SolutionDescriptor<Solution_> getSolutionDescriptor()

Specified by:

getSolutionDescriptor in class org.optaplanner.constraint.streams.common.InnerConstraintFactory<Solution_,BavetConstraint<Solution_>>
