Method Detail

insert

public final void insert(InTuple_ tuple)

Specified by:

insert in interface TupleLifecycle<InTuple_ extends AbstractTuple>

update

public final void update(InTuple_ tuple)

Specified by:

update in interface TupleLifecycle<InTuple_ extends AbstractTuple>

retract

public final void retract(InTuple_ tuple)

Specified by:

retract in interface TupleLifecycle<InTuple_ extends AbstractTuple>

accumulate

protected abstract Runnable accumulate(ResultContainer_ resultContainer,
                                       InTuple_ tuple)

getPropagator

public Propagator getPropagator()

Description copied from class: AbstractNode

Instead of calling the propagation directly from here, we export the propagation queue and allow BavetConstraintSession to call it. This is done with the idea that Propagator only has two implementations (unlike AbstractNode with myriad implementations) and therefore JVM call site optimizations will kick in to make the method dispatch faster.

Specified by:

getPropagator in class AbstractNode

Returns:

never null; the PropagationQueue in use by this node

createOutTuple

protected abstract OutTuple_ createOutTuple(GroupKey_ groupKey)

Parameters:

groupKey - null if the node only has one group

Returns:

never null

updateOutTupleToResult

protected abstract void updateOutTupleToResult(OutTuple_ outTuple,
                                               Result_ result)
