      Returns this channel's file position;

      Specified by:

      position in interface FileReadChannel

      Returns:

      This channel's file position, a non-negative integer counting the number of bytes from the beginning of the file to the current position

      Throws:

      java.io.IOException - If any problem occurs

    • position

      public FileReadChannel position(long newPosition)
                               throws java.io.IOException

      Description copied from interface: FileReadChannel
      Sets this channel's file position.

      Setting the position to a value that is greater than the file's size will not result in an exception. A later attempt to read bytes at such a position will immediately return an end-of-file indication.

      Specified by:

      position in interface FileReadChannel

      Parameters:

      newPosition - The new position, a non-negative integer counting the number of bytes from the beginning of the file

      Returns:

      This channel

      Throws:

      java.io.IOException - If any other problem occurs
