类 MurmurHash

java.lang.Object

redis.clients.jedis.util.MurmurHash

所有已实现的接口:

Hashing

public class MurmurHash
extends java.lang.Object
implements Hashing

This is a very fast, non-cryptographic hash suitable for general hash-based lookup. See http://murmurhash.googlepages.com/ for more details.

The C version of MurmurHash 2.0 found at that site was ported to Java by Andrzej Bialecki (ab at getopt org).

hash

public static int hash(byte[] data,
                       int seed)

Hashes bytes in an array.

参数:

data - The bytes to hash.

seed - The seed for the hash.

返回:

The 32 bit hash of the bytes in question.

hash

public static int hash(byte[] data,
                       int offset,
                       int length,
                       int seed)

Hashes bytes in part of an array.

参数:

data - The data to hash.

offset - Where to start munging.

length - How many bytes to process.

seed - The seed to start with.

返回:

The 32-bit hash of the data in question.

hash

public static int hash(java.nio.ByteBuffer buf,
                       int seed)

Hashes the bytes in a buffer from the current position to the limit.

参数:

buf - The bytes to hash.

seed - The seed for the hash.

返回:

The 32 bit murmur hash of the bytes in the buffer.
