Constructor and Description |
---|
XinA(IntVar x,
SetVar a)
It constructs an XinA constraint to restrict the domain of the variables X and A.
|
XinA(IntVar x,
SetVar a,
boolean strict)
It constructs an XinY constraint to restrict the domain of the variables X and Y.
|
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.
|
String |
id()
It gives the id string of a constraint.
|
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 |
queueVariable(int level,
Var variable)
This is a function called to indicate which variable in a scope of
constraint has changed.
|
void |
removeConstraint()
It removes the constraint by removing this constraint from all variables.
|
boolean |
satisfied()
It checks if the constraint is satisfied.
|
String |
toString()
It produces a string representation of a constraint state.
