It specifies set variable b.

It specifies set variable c.
|
boolean |
performCardinalityReasoning
It specifies if the constrain attempts to perform expensive and yet
unlikely propagation due to cardinality information.

It specifies the arguments required to be saved by an XML format as well as
the constructor being called to recreate an object from an XML format.

AintersectBeqC(SetVar a,
SetVar b,
SetVar c)
It constructs an AintersectBeqC constraint.
|
| 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 |
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.
