Constructor Detail

AbstractMapNode

protected AbstractMapNode(int inputStoreIndex,
                          TupleLifecycle<OutTuple_> nextNodesTupleLifecycle,
                          int outputStoreSize)

Method Detail

insert

public final void insert(InTuple_ tuple)

Specified by:

insert in interface TupleLifecycle<InTuple_ extends AbstractTuple>

map

protected abstract OutTuple_ map(InTuple_ inTuple)

update

public final void update(InTuple_ tuple)

Specified by:

update in interface TupleLifecycle<InTuple_ extends AbstractTuple>

remap

protected abstract boolean remap(InTuple_ inTuple,
                                 OutTuple_ oldOutTuple)

Parameters:

inTuple - never null; the tuple to apply mappings on

oldOutTuple - never null; the tuple that was previously mapped to the inTuple

Returns:

true if oldOutTuple changed during remapping

retract

public final void retract(InTuple_ tuple)

Specified by:

retract in interface TupleLifecycle<InTuple_ extends AbstractTuple>

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
