public static class RegionSplitter.HexStringSplit
extends RegionSplitter.NumberStringSplit

HexStringSplit is a well-known RegionSplitter.SplitAlgorithm for choosing region boundaries. The format of a HexStringSplit region boundary is the ASCII representation of an MD5 checksum, or any other uniformly distributed hexadecimal value. Row are hex-encoded long values in the range "00000000" => "FFFFFFFF" and are left-padded with zeros to keep the same order lexicographically as if they were binary. Since this split algorithm uses hex strings as keys, it is easy to read & write in the shell but takes up more space and may be non-intuitive.
