Eq(PrimitiveConstraint c1,
PrimitiveConstraint c2)
It constructs equality constraint between two constraints.
|
| 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() |
protected int |
getDefaultNotConsistencyPruningEvent() |
int |
getNestedPruningEvent(Var var,
boolean mode)
It retrieves the pruning event for which any composed constraint which
uses this constraint should be evaluated.
|
int |
getNotConsistencyPruningEvent(Var var)
It retrieves the pruning event which causes reevaluation of the
constraint notConsistency() function.
|
void |
notConsistency(Store store)
It makes pruning in such a way that constraint is notConsistent.
|
boolean |
notSatisfied()
It checks if constraint would be always not satisfied.
|
void |
queueVariable(int level,
Var var)
This is a function called to indicate which variable in a scope of
constraint has changed.
|
boolean |
satisfied()
It checks if the constraint is satisfied.
|
String |
toString()
It produces a string representation of a constraint state.
