public class EqBool extends PrimitiveConstraint
Modifier and Type | Field and Description |
---|---|
IntVar[] |
list
It specifies x variables in the constraint.
|
IntVar |
result
It specifies variable result in the constraint.
|
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 |
---|
EqBool(ArrayList<? extends IntVar> list,
IntVar result)
It constructs eqBool.
|
EqBool(IntVar[] list,
IntVar result)
It constructs eqBool.
|
Modifier and Type | Method and Description |
---|---|
ArrayList<Var> |
arguments()
It returns the variables in a scope of the constraint.
|
String |
checkInvariants()
It checks invariants required by the constraint.
|
void |
consistency(Store store)
It is a (most probably incomplete) consistency function which removes the
values from variables domains.
|
ArrayList<Constraint> |
decompose(Store store)
It returns an array list of constraint which are used to decompose this
constraint.
|
int |
getConsistencyPruningEvent(Var var)
It retrieves the pruning event which causes reevaluation of the
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 |
imposeDecomposition(Store store)
It imposes the decomposition of the given 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.
|
String |
toString()
It produces a string representation of a constraint state.
