所有已实现的接口:

Comparable<byte[]>

@InterfaceAudience.Public
public class BinaryPrefixComparator
extends ByteArrayComparable

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 BinaryComparator.

compareTo

public int compareTo(byte[] value,
                     int offset,
                     int length)

指定者:

compareTo 在类中 ByteArrayComparable

compareTo

                     int offset,
                     int length)

覆盖:

compareTo 在类中 ByteArrayComparable

toByteArray

public byte[] toByteArray()

指定者:

toByteArray 在类中 ByteArrayComparable

返回:

The comparator serialized using pb

parseFrom

public static BinaryPrefixComparator parseFrom(byte[] pbBytes)
                                        throws DeserializationException

参数:

pbBytes - A pb serialized BinaryPrefixComparator instance

返回:

An instance of BinaryPrefixComparator made from bytes

抛出:

DeserializationException
