|---|
Table(IntVar[] list,
int[][] tuples)
It constructs a table constraint.
|
Table(IntVar[] list,
int[][] tuples,
boolean reuseTuplesArgument)
It constructs a table 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.
|
void |
queueVariable(int level,
Var v)
This is a function called to indicate which variable in a scope of
constraint has changed.
|
void |
removeLevel(int level)
This function is called in case of the backtrack, so a constraint can
clear the queue of changed variables which is no longer valid.
|
String |
toString()
It produces a string representation of a constraint state.
