synchronize

Syntax

constraint synchronize(intervalVar interval, intervalVarArray array)

Parameters

• interval: interval variable.
• array: array of interval variables synchronized with interval.

Description

This function creates a synchronization constraint between an interval variable interval and a set of interval variables in array. This constraint makes all present intervals in array start and end together with interval, if it is present.

Example

a  = intervalVar(size=10..20);
b1 = intervalVar(optional);  
b2 = intervalVar(optional);  
b3 = intervalVar(optional);  
// If an interval b is present it must start and end at the same value as interval a
synchronize(a, [b1,b2,b3]);

Notes

The synchronize constraint is the same as a set of startAtStart and endAtEnd constraints between interval variable interval and each of the interval variables in array.
