Method Detail
-
propagate
public void propagate(int evtmask) throws ContradictionException
Description copied from class:Propagator
Call the main filtering algorithm to apply to theDomain
of theVariable
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:
- at the initial propagation step,
- when involved in a reified constraint.
It should initialized the internal data structure and apply filtering algorithm from scratch.- Specified by:
propagate
in classPropagator<IntVar>
- Parameters:
evtmask
- type of propagation eventthis
must consider.- Throws:
ContradictionException
- when a contradiction occurs, like domain wipe out or other incoherencies.
-
propagate
public void propagate(int idxVarInProp, int mask) throws ContradictionException
Description copied from class:Propagator
Incremental filtering algorithm defined within thePropagator
, 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 totrue
in the constructor. Otherwise, it executespropagate(PropagatorEventType.CUSTOM_PROPAGATION.getStrengthenedMask());
- Overrides:
propagate
in classPropagator<IntVar>
- Parameters:
idxVarInProp
- index of the variablevar
inthis
mask
- type of event- Throws:
ContradictionException
- if a contradiction occurs
