All Implemented Interfaces:

Enclosing class:

RangeTombstone

public static class RangeTombstone.Bound
extends Slice.Bound

The bound of a range tombstone.

This is the same than for a slice but it includes "boundaries" between ranges. A boundary simply condensed a close and an opening "bound" into a single object. There is 2 main reasons for these "shortcut" boundaries: 1) When merging multiple iterators having range tombstones (that are represented by their start and end markers), we need to know when a range is close on an iterator, if it is reopened right away. Otherwise, we cannot easily produce the markers on the merged iterators within risking to fail the sorting guarantees of an iterator. See this comment for more details: https://goo.gl/yyB5mR. 2) This saves some storage space.
