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)

Adds a pair (interval, demand) to the constraint.

addDemand

public CumulativeConstraint addDemand(IntervalVar interval,
 long demand)

Adds a pair (interval, demand) to the constraint.

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
