Method Detail

hashMurmur32

public static long hashMurmur32(byte mask,
                                long length,
                                byte[] data)

Computes a MurmurHash3 hash value for the provided data components.

This method combines a byte mask, a long length value, and a byte array into a single byte sequence using little-endian byte ordering, then computes a 32-bit MurmurHash3 hash of this sequence, returned as an unsigned long.

Parameters:

mask - A byte value to include in the hash computation

length - A long value to include in the hash computation (stored in little-endian order)

data - The byte array data to include in the hash computation

Returns:

The computed MurmurHash3 value as an unsigned 32-bit integer converted to long
