Examples of BinaryPrefixComparator

org.apache.hadoop.hbase.filter.BinaryPrefixComparator
A comparator which compares against a specified byte array, but only compares up to the length of this byte array. For the rest it is similar to {@link BinaryComparator}.
org.hbase.async.BinaryPrefixComparator
A binary comparator used in comparison filters. Compares byte arrays lexicographically up to the length of the provided byte array. @since 1.6
