throws ContradictionException
PropagatorDomain of the Variable objects.
It considers the current state of this objects to remove some values from domains and/or instantiate some variables.
Calling this method is done from 2 (and only 2) steps:
propagate in class Propagator<BoolVar>evtmask - type of propagation event this must consider.ContradictionException - when a contradiction occurs, like domain wipe out or other incoherencies.public void propagate(int idxVarInProp,
int mask)
throws ContradictionException
PropagatorPropagator, called whenever the variable
of index idxVarInProp has changed. This method calls a CUSTOM_PROPAGATION (coarse-grained) by default.
This method should be overridden if the argument reactToFineEvt is set to true in the constructor.
Otherwise, it executes propagate(PropagatorEventType.CUSTOM_PROPAGATION.getStrengthenedMask());
