Method Details

getStreamKind

public StreamKind getStreamKind()

Specified by:

getStreamKind in class AbstractNode

getPropagator

public final 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

allowsInstancesOf

public final boolean allowsInstancesOf(Class<?> clazz)

Specified by:

allowsInstancesOf in interface BavetRootNode<Tuple_ extends Tuple>

getSourceClasses

public final Class<?>[] getSourceClasses()

Specified by:

getSourceClasses in interface BavetRootNode<Tuple_ extends Tuple>

supports

public final boolean supports(BavetRootNode.LifecycleOperation lifecycleOperation)

Description copied from interface: BavetRootNode

Determines if this node supports the given lifecycle operation. Unsupported nodes will not be called during that lifecycle operation.

Specified by:

supports in interface BavetRootNode<Tuple_ extends Tuple>

Parameters:

lifecycleOperation - the lifecycle operation to check

Returns:

true if the given lifecycle operation is supported; otherwise, false.

insert

public final void insert(@Nullable Object a)

Specified by:

insert in interface BavetRootNode<Tuple_ extends Tuple>

update

public final void update(@Nullable Object a)

Specified by:

update in interface BavetRootNode<Tuple_ extends Tuple>

retract

public final void retract(@Nullable Object a)

Specified by:

retract in interface BavetRootNode<Tuple_ extends Tuple>

remapTuple

protected abstract Tuple_ remapTuple(Tuple_ tuple)
