Global Constraints

The global constraints are:

const IloInt IloRestoreNothing,
             IloRestoreActivityStart,
             IloRestoreActivityEnd,
             IloRestoreActivityDuration,
             IloRestoreActivityProcessingTime,
             IloRestoreActivityExternal,
             IloRestoreRCNext,
             IloRestoreRCPrev,
             IloRestoreRCDirectPredecessor,
             IloRestoreRCDirectSuccessor,
             IloRestoreRCSetup,
             IloRestoreRCTeardown,
             IloRestoreRCCapacity,
             IloRestoreRCSelected,
             IloRestoreAll;

Global constants are used to parameterize the restoration of IloActivity and IloResourceConstraint objects in the following four contexts.

Local search
An IloRestoreSolution goal
IloSolution::getConstraint method
IloSolution::restore method

In each of these contexts, the data that is restored (that is, inserted into the solver or, in the case of IloSolution::getConstraint added, via a constraint, to the model) depends on the value of the restoreFields flag that is associated with the extractable. The restoreFields are associated with an extractable in the IloSchedulerSolution::add method or by using the IloSchedulerSolution::setRestorable and IloSchedulerSolution::setNonRestorable methods.

Value	Field
`IloRestoreNothing`	none
`IloRestoreActivityStart`	start time variable of an `IloActivity`
`IloRestoreActivityEnd`	end time variable of an `IloActivity`
`IloRestoreActivityDuration`	duration variable of an `IloActivity`
`IloRestoreActivityProcessingTime`	processing time variable of an `IloActivity`
`IloRestoreActivityExternal`	external variable associated with an `IloActivity`
`IloRestoreRCNext`	next relation of an `IloResourceConstraint`
`IloRestoreRCPrev`	previous relation of an `IloResourceConstraint`
`IloRestoreRCDirectSuccessor`	direct successors of an `IloResourceConstraint`
`IloRestoreRCDirectPredecessor`	direct predecessors of an `IloResourceConstraint`
`IloRestoreRCSetup`	setup status of an `IloResourceConstraint`
`IloRestoreRCTeardown`	teardown status of an `IloResourceConstraint`
`IloRestoreRCCapacity`	capacity variable of an `IloResourceConstraint`
`IloRestoreRCSelected`	selected resource of an `IloResourceConstraint`
`IloRestoreAll`	all possible restorable fields of the associated extractable
