    int
    hash(byte[] payload)
    Hashes a byte array efficiently.
    int
    hash(int hashcode)
    An incremental version of the hash function, that spreads a pre-calculated hash code, such as one derived from Object.hashCode().
    int
    hash(Object o)
    A helper that calculates the hashcode of an object, choosing the optimal mechanism of hash calculation after considering the type of the object (byte array, String or Object).
    int
    maxHashBits()

    • getInstance

      public static CRC16 getInstance()

    • hash

      public int hash(byte[] payload)
      Description copied from interface: Hash
      Hashes a byte array efficiently.
      Specified by:
      hash in interface Hash
      Parameters:
      payload - a byte array to hash
      Returns:
      a hash code for the byte array

    • maxHashBits

      public int maxHashBits()
      Description copied from interface: Hash
      How many bits this hash function may utilize. By default a hash algorithm is assumed to use all 32 bits producing a value in the full range of int values.
      Specified by:
      maxHashBits in interface Hash
      Returns:
      how many bits the resulting int may use

    • hash

      public int hash(int hashcode)
      Description copied from interface: Hash
      An incremental version of the hash function, that spreads a pre-calculated hash code, such as one derived from Object.hashCode().
      Specified by:
      hash in interface Hash
      Parameters:
      hashcode - an object's hashcode
      Returns:
      a spread and hashed version of the hashcode

    • hash

      public int hash(Object o)
      Description copied from interface: Hash
      A helper that calculates the hashcode of an object, choosing the optimal mechanism of hash calculation after considering the type of the object (byte array, String or Object).
      Specified by:
      hash in interface Hash
      Parameters:
      o - object to hash
      Returns:
      a hashcode
