Enumeration IlcFailReason

This enumeration is used to describe the reason of a failure, if it is known to the Scheduler Engine. See IlcSchedulerTraceI::getFailReason.

The values IlcFailActivityNoStartOverlapVariable and IlcFailActivityNoEndOverlapVariable mean that an activity was to overlap a break at its start (or end, respectively), but no start (or end, respectively) overlap variable was defined.

The values IlcFailAltResConstraint and IlcFailAltResConstraintOpposite mean that a resource constraint (or its opposite, respectively) was to be propagated, but this led to a failure.

The value IlcFailAtConstraintOpposite means that the opposite of an "at constraint" was to be propagated but this led to a failure.

The value IlcFailBalanceConstraint means that the balance constraint was propagated and it led to a failure. If the fail reason is associated with a resource constraint rct, it means that the balance constraint detected that the resource is over-consumed, or the reservoir overflows or underflows just before or after rct. In case this fail reason is not associated with any resource constraint, it means that the balance constraint has detected a global failure.

The values IlcFailDisjunctive, IlcFailEdgeFinder, IlcFailBreakConstraint, IlcFailCapTimetable, IlcFailContinuousTimetable, IlcFailPrecedenceConstraint, IlcFailStateTimetable, and IlcFailTypeTimetable mean that the corresponding constraint has detected a failure condition.

The values with the prefix IlcFailPrecedenceGraph mean that the named modification was to be made, but this led to a failure.

The values IlcFailResourceConstraint and IlcFailResourceConstraintOpposite mean that a resource constraint (or its opposite, respectively) was to be propagated, but this led to a failure.

The values IlcFailResourceIntegralConstraint and IlcFailResourceFunctionalConstraint mean that resource integral or resource functional constraint was to be propagated, but this led to a failure.

The value IlcFailTimeBoundConstraint means that a time-bound constraint was to be propagated, but this led to a failure.
