Method Details

getPropagator

public abstract Propagator getPropagator()

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.

Returns:

never null; the PropagationQueue in use by this node

getStreamKind

public abstract StreamKind getStreamKind()

getId

public long getId()

setId

public final void setId(long id)

getLocationSet

public SortedSet<ConstraintNodeLocation> getLocationSet()

addLocationSet

public void addLocationSet(Set<ConstraintNodeLocation> locationSet)

setLayerIndex

public final void setLayerIndex(long layerIndex)

getLayerIndex

public final long getLayerIndex()

toString

public String toString()

Overrides:
