      • getStreamSegment

        public StreamSegment getStreamSegment​(long position,
                                      int length)
        Description copied from interface: StreamSegmentMapper
        Returns a StreamSegment object indicating the location of the initial portion of a desired segment in the source stream. The length of the returned StreamSegment may be smaller than the desired length.
        Specified by:
        getStreamSegment in interface StreamSegmentMapper
        Parameters:
        position - The desired starting position in the SegmentedImageInputStream, as a long.
        length - The desired segment length.
        Returns:
        a StreamSegment object

        public void getStreamSegment​(long position,
                             int length,
                             StreamSegment seg)
        Description copied from interface: StreamSegmentMapper
        Sets the values of a StreamSegment object indicating the location of the initial portion of a desired segment in the source stream. The length of the returned StreamSegment may be smaller than the desired length.
        Specified by:
        getStreamSegment in interface StreamSegmentMapper
        Parameters:
        position - The desired starting position in the SegmentedImageInputStream, as a long.
        length - The desired segment length.
        seg - A StreamSegment object to be overwritten.
