Constructor and Description |
---|
CardA(SetVar a,
int c)
It constructs a cardinality constraint to restrict the number of elements
in the set assigned to a set variable a.
|
CardA(SetVar a,
IntDomain c)
It constructs a cardinality constraint to restrict the number of elements
in the set assigned to set variable a.
|
CardA(SetVar a,
int min,
int max)
It constructs a cardinality constraint to restrict the number of elements
in the set assigned to set variable a.
|
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.
|
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 |
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.
