    • get

      public int get(long offset)
      Description copied from interface: RandomAccessSource
      Gets a byte at the specified position
      Specified by:
      get in interface RandomAccessSource
      Parameters:
      offset -
      Returns:
      the byte, or -1 if EOF is reached

    • get

      public int get(long offset, byte[] bytes, int off, int len)
      Description copied from interface: RandomAccessSource
      Gets an array at the specified position. If the number of bytes requested cannot be read, the bytes that can be read will be placed in bytes and the number actually read will be returned.

      get in interface RandomAccessSource
      Parameters:
      offset - the position in the RandomAccessSource to read from
      bytes - output buffer
      off - offset into the output buffer where results will be placed
      len - the number of bytes to read
      Returns:
      the number of bytes actually read, or -1 if the file is at EOF

      Returns:
      the length of this source
