Method Detail

getFilteredEventMask

public int getFilteredEventMask(int idx)
Overrides:
getFilteredEventMask in class Propagator

propagate

public void propagate()
               throws ContradictionException
Propagation: Propagating the constraint until local consistency is reached.

Specified by:
propagate in class Propagator
Throws:
ContradictionException - contradiction exception

isSatisfied

public boolean isSatisfied(int[] tuple)
Description copied from class: AbstractIntSConstraint
TEMPORARY: if not overriden by the constraint, throws an error to avoid bug using reified constraints in constraints that have not been changed to fulfill this api yet !

Specified by:
isSatisfied in interface IntPropagator
Overrides:
isSatisfied in class AbstractIntSConstraint

isEntailed

public Boolean isEntailed()
Description copied from class: AbstractSConstraint
Indicates if the constraint is entailed, from now on will be always satisfied

Overrides:
isEntailed in class AbstractSConstraint<IntDomainVar>
Returns:
wether the constraint is entailed

opposite

public AbstractSConstraint<IntDomainVar> opposite(Solver solver)
Get the opposite constraint

Specified by:
opposite in interface SConstraint<IntDomainVar>
Overrides:
opposite in class AbstractSConstraint<IntDomainVar>
Parameters:
solver - the current solver
Returns:
the opposite constraint @param solver
