public class Reified extends Constraint
Modifier and Type | Field and Description |
---|---|

b
It specifies variable b which stores status of the constraint (0 - for certain not satisfied, 1 - for certain satisfied).
|
PrimitiveConstraint |
c
It specifies constraint c which status is being checked.
|
static String[] |
xmlAttributes
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.

Constructor and Description |
---|
Reified(PrimitiveConstraint c,
IntVar b)
It creates Reified 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.
|
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.
|
void |
removeLevelLate(int level)
This function is called in case of the backtrack.
|
boolean |
satisfied()
It checks if the constraint is satisfied.
|
String |
toString()
It produces a string representation of a constraint state.
