Constructor and Description 

SumWeightedSet(SetVar a,
int[] elements,
int[] weights,
IntVar totalWeight)
It constructs a weighted set sum constraint.

SumWeightedSet(SetVar a,
int[] weights,
IntVar totalWeight)
It constructs a weighted set sum constraint.

SumWeightedSet(SetVar a,
IntVar totalWeight)
It constructs a weighted set sum 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 
getConsistencyPruningEvent(Var var)
It retrieves the pruning event which causes reevaluation of the
constraint.

int 
getDefaultConsistencyPruningEvent() 
boolean 
satisfied()
It checks if the constraint is satisfied.

String 
toString()
It produces a string representation of a constraint state.
