Class Murmur3Hasher
org.elasticsearch.common.hash.Murmur3Hasher
public class Murmur3Hasher
extends
Wraps that
allows hashing of byte arrays passed through multiple calls to
update(byte[])
. Like
, this class maintains internal state during the calculation of the
hash and is not threadsafe. If concurrent hashes are to be computed, each must be done on a
separate instance.-

Method Details
-
update
public void update(byte[] inputBytes)Supplies some or all of the bytes to be hashed. Multiple calls to this method may be made to sequentially supply the bytes for hashing. Once all bytes have been supplied, thedigest()
method should be called to complete the hash calculation. -
reset
public void reset()Clears all bytes previously passed toupdate(byte[])
and prepares for the calculation of a new hash. -
digest
public byte[] digest()Completes the hash of all bytes previously passed toupdate(byte[])

getAlgorithm
public getAlgorithm() -
toHash128
Converts the 128-bit byte array returned bydigest()
to aMurmurHash3.Hash128
