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 |
---|---|
void |
consistency(Store store)
It is a (most probably incomplete) consistency function which removes the
values from variables domains.
|
int |
getDefaultConsistencyPruningEvent() |
boolean |
satisfied()
It checks if the constraint is satisfied.
|
String |
toString()
It produces a string representation of a constraint state.
