public class Binpacking extends Constraint
Modifier and Type | Field and Description |
---|---|
JaCoP.constraints.binpacking.BinItem[] |
item
It keeps together a list of variables which define bin for item i and
their weigts.
|
IntVar[] |
load
It specifies a list of variables which define bin load.
|
static java.lang.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 |
---|
Binpacking(java.util.ArrayList<? extends IntVar> bin,
java.util.ArrayList<? extends IntVar> load,
int[] w)
It constructs the binpacking constraint for the supplied variable.
|
Binpacking(IntVar[] bin,
IntVar[] load,
int[] w)
It constructs the binpacking constraint for the supplied variable.
|
Modifier and Type | Method and Description |
---|---|
java.util.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.
|
java.lang.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 |
queueVariable(int level,
Var V)
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clear the queue of changed variables which is no longer valid.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.
|
java.lang.String |
toString()
It produces a string representation of a constraint state.
