dom
It specifies domain d which restricts the possible value of the specified variable.
|
IntVar |
x
It specifies variable x whose domain must lie within a specified domain.
|
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 |
---|
In(IntVar x,
IntDomain dom)
It constructs an In constraint to restrict the domain of the variable.
|
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.
|
Constraint |
getGuideConstraint()
It specifies a constraint which if imposed by search will enhance
propagation of this constraint.
|
int |
getGuideValue()
This function provides a value which if assigned to a variable returned
by getGuideVariable() will enhance propagation of this constraint.
|
Var |
getGuideVariable()
This function provides a variable which assigned a value returned
by will enhance propagation of this constraint.
|
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 |
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 |
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 |
removeConstraint()
It removes the constraint by removing this constraint from all variables.
|
boolean |
satisfied()
It checks if the constraint is satisfied.
|
void |
supplyGuideFeedback(boolean feedback)
This function allows to provide a guide feedback.
|
String |
toString()
It produces a string representation of a constraint state.
