Propagatorobject can react.
IEventTypethis can react on. For example, consider a propagator that can deduce filtering based on the lower bound of the integer variable X. Then, for this variable, the mask should be equal to :
int mask = IntEventType.INCLOW.getMask() | IntEventType.INSTANTIATE.getMask();or, in a more convenient way:
int mask = IntEvtType.combine(IntEventType.INCLOW,IntEventType.INSTANTIATE);That indicates the following behavior:
IntEventType.VOIDwhich states that this propagator should not be aware of modifications applied to the variable in position vIdx.
public void propagate(int evtmask) throws ContradictionException
Variableobjects. 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:
public void propagate(int i, int mask) throws ContradictionException
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
public ESat isEntailed()
thisis entailed according to the current state of its internal structure. At least, should check the satisfaction of
this(when all is instantiated).
