Assignment(ArrayList<? extends IntVar> xs,
ArrayList<? extends IntVar> ds)
It constructs an Assignment constraint with shift equal 0.
|
Assignment(ArrayList<? extends IntVar> xs,
ArrayList<? extends IntVar> ds,
int shiftX,
int shiftD)
It enforces the relationship x[d[i]-shiftX]=i+shiftD and
d[x[i]-shiftD]=i+shiftX.
|
Assignment(ArrayList<? extends Var> xs,
ArrayList<? extends Var> ds,
int min)
It enforces the relationship x[d[i]-min]=i+min and
d[x[i]-min]=i+min.
|
Assignment(IntVar[] xs,
IntVar[] ds)
It constructs an Assignment constraint with shift equal 0.
|
Assignment(IntVar[] xs,
IntVar[] ds,
int min)
It enforces the relationship x[d[i]-min]=i+min and
d[x[i]-min]=i+min.
|
Assignment(IntVar[] xs,
IntVar[] ds,
int shiftX,
int shiftD)
It enforces the relationship x[d[i]-shiftX]=i+shiftD and
d[x[i]-shiftD]=i+shiftX.

| 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 var)
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 |
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clear the queue of changed variables which is no longer valid.
|
boolean |
satisfied()
It checks if the constraint is satisfied.
|
String |
toString()
It produces a string representation of a constraint state.
