Method Details

guaranteesDistinct

public boolean guaranteesDistinct()

Description copied from class: BavetAbstractConstraintStream

Whether the stream guarantees that no two tuples it produces will ever have the same set of facts. Streams which can prove that they either do or do not produce unique tuples should override this method.

Specified by:

guaranteesDistinct in interface InnerBiConstraintStream<Solution_,A>

Overrides:

guaranteesDistinct in class BavetAbstractConstraintStream<Solution_>

Returns:

delegates to BavetAbstractConstraintStream.getParent() if not null, otherwise false

collectActiveConstraintStreams

public void collectActiveConstraintStreams(Set<BavetAbstractConstraintStream<Solution_>> constraintStreamSet)

Overrides:

collectActiveConstraintStreams in class BavetAbstractConstraintStream<Solution_>

buildNode

public <Score_ extends Score<Score_>> void buildNode(ConstraintNodeBuildHelper<Solution_,Score_> buildHelper)

Specified by:

buildNode in class BavetAbstractConstraintStream<Solution_>

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

getLeftParent

public BavetAbstractConstraintStream<Solution_> getLeftParent()

Specified by:

getLeftParent in interface BavetConstraintStreamBinaryOperation<Solution_>

Specified by:

getLeftParent in interface BavetStreamBinaryOperation<Solution_>

Returns:

An instance of BavetForeBridgeUniConstraintStream.

getRightParent

public BavetAbstractConstraintStream<Solution_> getRightParent()

Specified by:

getRightParent in interface BavetConstraintStreamBinaryOperation<Solution_>

Specified by:

getRightParent in interface BavetStreamBinaryOperation<Solution_>

Returns:

An instance of BavetForeBridgeUniConstraintStream.
