    • writeShort

      public static void writeShort(short value, byte[] byteArray, int offset, boolean bigEndian)
      Copies the short value into two consecutive bytes of the byte array starting at the offset.
      Parameters:
      value - the short value to marshall
      byteArray - destination
      offset - offset in the byte array
      bigEndian - if false the bytes will be copied in reverse (little endian) order
      Throws:
      NullPointerException - if byteArray is null
      ArrayIndexOutOfBoundsException - if an invalid array access occurs

    • writeShort
