      • bits

        public int bits()
        Description copied from interface: HashFunction
        Returns the number of bits (a multiple of 32) that each hash code produced by this hash function has.
        Specified by:
        bits in interface HashFunction
      • newHasher

        public Hasher newHasher()
        Description copied from interface: HashFunction
        Begins a new hash code computation by returning an initialized, stateful Hasher instance that is ready to receive data. Example:
           
        
           HashFunction hf = Hashing.md5();
           HashCode hc = hf.newHasher()
               .putLong(id)
               .putBoolean(isActive)
               .hash();
