Constructor and Description |
---|
CountValuesBounds(IntVar[] list,
int[] lb,
int[] ub,
int[] values)
It constructs a CountValuesBounds constraint.
|
CountValuesBounds(List<? extends IntVar> list,
int[] lb,
int[] ub,
int[] values)
It constructs a CountValuesBounds constraint.
|
Modifier and Type | Method and Description |
---|---|
void |
consistency(Store store)
It is a (most probably incomplete) consistency function which removes the
values from variables domains.
|
int |
getDefaultConsistencyPruningEvent() |
void |
impose(Store store)
It imposes the constraint in a given store.
|
boolean |
satisfied()
It checks if the constraint is satisfied.
|
String |
toString()
It produces a string representation of a constraint state.

Implementations of this interface for constraints that are not PrimitiveConstraint may require constraint imposition and consistency check as a requirement to work correctly.
