Description

inherits Calendar.TimeRange

This class handles the cases where you have a time period with holes. These can be created by the ^ or | operators on time ranges.

Constant nulltimerange

constant Calendar.SuperTimeRange()->nulltimerange = object(TimeRange)

Description

This represents the null time range, which, to differ from the zero time range (the zero-length time range), isn't placed in time. This is the result of for instance `& between two strict non-overlapping timeranges - no time at all.

It has a constant, is_nulltimerange, which is non-zero. `! on this timerange is true.
