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
