C# Class Deveel.Data.Index.IndexRange

Describes the range of values to select from an index.
A range has a start value, an end value, and whether we should pick inclusive or exclusive of the end value. The start value may be a concrete value from the set or it may be a flag that represents the start or end of the list.

Note that the the start value may not compare less than the end value. For example, start can not be RangeFieldOffset.LastValue and end can not be RangeFieldOffset.FirstValue.
