      • get

        public int get​(long offset)
        Description copied from interface: IRandomAccessSource
        Gets a byte at the specified position
        Specified by:
        get in interface IRandomAccessSource
        Parameters:
        offset - byte position
        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: IRandomAccessSource
        Read an array of bytes of specified length from the specified position of source to the buffer applying the offset. If the number of bytes requested cannot be read, all the possible bytes will be read to the buffer, and the number of actually read bytes will be returned.
        Specified by:
        get in interface IRandomAccessSource
        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

      • close

        public void close()
           throws java.io.IOException
        Description copied from interface: IRandomAccessSource
        Closes this source. The underlying data structure or source (if any) will also be closed
        Specified by:
        close in interface IRandomAccessSource
        Throws:
        java.io.IOException - in case of any reading error.
