Constructor and Description |
---|
NoGood(ArrayList<? extends IntVar> listOfVars,
ArrayList<Integer> listOfValues)
It creates a no-good constraint.
|
NoGood(IntVar[] listOfVars,
int[] listOfValues)
It creates a no-good constraint.
|
Modifier and Type | Method and Description |
---|---|
ArrayList<Var> |
arguments()
It returns the variables in a scope of the constraint.
|
void |
consistency(Store store)
It is a (most probably incomplete) consistency function which removes the
values from variables domains.
|
int |
getConsistencyPruningEvent(Var var)
It retrieves the pruning event which causes reevaluation of the
constraint.
|
int |
getNestedPruningEvent(Var var,
boolean mode)
It retrieves the pruning event for which any composed constraint which
uses this constraint should be evaluated.
|
int |
getNotConsistencyPruningEvent(Var var)
It retrieves the pruning event which causes reevaluation of the
constraint notConsistency() function.
|
void |
impose(Store store)
It imposes the constraint in a given store.
|
void |
increaseWeight()
It increases the weight of the variables in the constraint scope.
|
void |
notConsistency(Store store)
It makes pruning in such a way that constraint is notConsistent.
|
boolean |
notSatisfied()
It checks if constraint would be always not satisfied.
|
void |
removeConstraint()
This function does nothing as constraints can not be removed for a given
level.
|
boolean |
satisfied()
First time consistency function does pruning is the last time it will be
called.
|
String |
toString()
It produces a string representation of a constraint state.
