All Implemented Interfaces:

Comparable<byte[]>

@InterfaceAudience.Public
public class BinaryComponentComparator
extends org.apache.hadoop.hbase.filter.ByteArrayComparable

A comparator which compares against a specified byte array, but only compares specific portion of the byte array. For the rest it is similar to BinaryComparator.
