    • createStateful

      StatefulLongHash createStateful()
      Returns a new instance of stateful version of this hash function.
      Specified by:
      createStateful in interface StatelessHash
      Returns:
      the stateful version of this hash function

    • calculate

      long calculate(byte[] input)
      Evaluates this hash function for the entire given input array.
      Parameters:
      input - the input array
      Returns:
      the output of the hash function

    • calculate

      long calculate(byte[] input, int index, int length)
      Evaluates this hash function for the given range of the given input array.
      Parameters:
      input - the input array
      index - the starting index of the first input byte
      length - the length of the input range
      Returns:
      the output of the hash function
      Throws:
      IndexOutOfBoundsException - if index is negative or index + length is greater than the array length

    • calculate

      long calculate(ByteBuffer input)
      Evaluates this hash function with the remaining contents of the given input buffer. This method leaves the buffer position at the limit.
      Parameters:
      input - the input buffer
      Returns:
      the output of the hash function

    • calculate

      long calculate(long address, long length)
      Evaluates this hash function for the memory with the given address and length. The arguments are generally not checked in any way and will likely lead to a VM crash or undefined results if invalid.
      Parameters:
      address - the base address of the input
      length - the length of the input
      Returns:
      the output of the hash function
      Throws:
      UnsupportedOperationException - if this function does not support unsafe memory access
