C++ Reference: class IntervalsRepository

Note: This documentation is automatically generated.

This class maintains a set of intervals which correspond to three integer variables (start, end and size). It automatically registers with the PrecedencesPropagator the relation between the bounds of each interval and provides many helper functions to add precedences relation between intervals.

Method
AllIntervals	Return type: std::vector<IntervalVariable> Utility function that returns a vector will all intervals.
CreateInterval	Return type: IntervalVariable Arguments: IntegerVariable start, IntegerVariable end, IntegerVariable size, IntegerValue fixed_size, LiteralIndex is_present Functions to add a new interval to the repository. If add_linear_relation is true, then we also link start, size and end. - If size == kNoIntegerVariable, then the size is fixed to fixed_size. - If is_present != kNoLiteralIndex, then this is an optional interval.
CreateInterval	Return type: IntervalVariable Arguments: AffineExpression start, AffineExpression end, AffineExpression size, LiteralIndex is_present, bool add_linear_relation
End	Return type: AffineExpression Arguments: IntervalVariable i
EndVar	Return type: IntegerVariable Arguments: IntervalVariable i
GetOrCreateHelper	Return type: SchedulingConstraintHelper* Arguments: const std::vector<IntervalVariable>& variables Returns a SchedulingConstraintHelper corresponding to the given variables. Note that the order of interval in the helper will be the same.
IntervalsRepository	Return type: explicit Arguments: Model* model
IsAbsent	Return type: bool Arguments: IntervalVariable i
IsOptional	Return type: bool Arguments: IntervalVariable i Returns whether or not a interval is optional and the associated literal.
IsPresent	Return type: bool Arguments: IntervalVariable i
MaxSize	Return type: IntegerValue Arguments: IntervalVariable i Return the maximum size of the given IntervalVariable.
MinSize	Return type: IntegerValue Arguments: IntervalVariable i Return the minimum size of the given IntervalVariable.
NumIntervals	Return type: int Returns the current number of intervals in the repository. The interval will always be identified by an integer in [0, num_intervals).
PresenceLiteral	Return type: Literal Arguments: IntervalVariable i
Size	Return type: AffineExpression Arguments: IntervalVariable i The 3 integer variables associated to a interval. Fixed size intervals will have a kNoIntegerVariable as size. Note: For an optional interval, the start/end variables are propagated asssuming the interval is present. Because of that, these variables can cross each other or have an empty domain. If any of this happen, then the PresenceLiteral() of this interval will be propagated to false.
SizeVar	Return type: IntegerVariable Arguments: IntervalVariable i Deprecated.
Start	Return type: AffineExpression Arguments: IntervalVariable i
StartVar	Return type: IntegerVariable Arguments: IntervalVariable i
