public class Match extends Constraint
Modifier and Type | Field and Description |
---|---|
SetVar |
a
It specifies a set variable whose values are being matched against integer variables
from the list.
|
IntVar[] |
list
It specifies the list of integer variables which value is being matched against
elements from a set variable a.
|
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 |
---|
Match(SetVar a,
IntVar[] list)
It constructs a match constraint to connect the value of set variable a
to the values of integer variables provided in the list.
|
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.
|
String |
id()
It gives the id string of a 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 |
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.
