Detailed Description

Segment corresponding to a fill region of the executable image.

Member Function Documentation

unsigned MemoryImageDataSource::FillSegment::getLength ( )

virtual

Returns a length based on the data target's address range.

The pattern segment's length is a function of the data target. If the target is bounded, then the segment's length is simply the target's length. Otherwise, if no target has been set or the target is unbounded, then the length returned is 0.

Reimplemented from elftosb::DataSource::PatternSegment.
