public class CumulativeConstraint
extends Constraint

Specialized cumulative constraint.

This constraint allows adding (interval, demand) pairs to the cumulative constraint incrementally.

Method Details

addDemand

public CumulativeConstraint addDemand(IntervalVar interval,
 LinearArgument demand)

addDemand

public CumulativeConstraint addDemand(IntervalVar interval,
 long demand)

addDemands

public CumulativeConstraint addDemands(IntervalVar[] intervals,
 LinearArgument[] demands)

Adds all pairs (intervals[i], demands[i]) to the constraint.

Parameters:

intervals - an array of interval variables

demands - an array of linear expression

Returns:

itself

Throws:

CpModel.MismatchedArrayLengths - if intervals and demands have different length

addDemands

public CumulativeConstraint addDemands(IntervalVar[] intervals,
 long[] demands)

Adds all pairs (intervals[i], demands[i]) to the constraint.

Parameters:

intervals - an array of interval variables

demands - an array of long values

Returns:

itself

Throws:

CpModel.MismatchedArrayLengths - if intervals and demands have different length

addDemands

public CumulativeConstraint addDemands(IntervalVar[] intervals,
 int[] demands)

Adds all pairs (intervals[i], demands[i]) to the constraint.

Parameters:

intervals - an array of interval variables

demands - an array of integer values

Returns:

itself

Throws:

CpModel.MismatchedArrayLengths - if intervals and demands have different length
