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.
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.
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.
