Propagator
Domain
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 PropCumulative
evtmask
- type of propagation event this
must consider.ContradictionException
- when a contradiction occurs, like domain wipe out or other incoherencies.public void propagate(int varIdx, int mask) throws ContradictionException
Propagator
Propagator
, 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());
