Comparable<byte[]>

@InterfaceAudience.Public
@InterfaceStability.Stable
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.

public BinaryPrefixComparator(byte[] value)

Constructor

参数:

value - value

方法详细资料

compareTo

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

从类复制的说明: ByteArrayComparable

Special compareTo method for subclasses, to avoid copying byte[] unnecessarily.

指定者:

compareTo 在类中 ByteArrayComparable

参数:

value - byte[] to compare

offset - offset into value

length - number of bytes to compare

返回:

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

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
