Method Detail

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

getStreamSegment

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.
