    • Method Detail

      • get

        public int get​(long offset)
        Description copied from interface: RandomAccessSource
        Gets a byte at the specified position
        Specified by:
        get in interface RandomAccessSource
        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.
        Specified by:
        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

      • length

        public long length()
        Specified by:
        length in interface RandomAccessSource
        Returns:
        the length of this source

      • close

        public void close()
           throws java.io.IOException
        Description copied from interface: RandomAccessSource
        Closes this source. The underlying data structure or source (if any) will also be closed
        Specified by:
