Member Function Documentation

bool geos::noding::IntersectionFinderAdder::isDone ( ) const

Always process all intersections

false always

Reimplemented from geos::noding::SegmentIntersector.

void geos::noding::IntersectionFinderAdder::processIntersections ( SegmentString e0,
size_t  segIndex0,
SegmentString e1,
size_t  segIndex1 

This method is called by clients of the SegmentIntersector class to process intersections for two segments of the SegmentStrings being intersected. Note that some clients (such as MonotoneChains) may optimize away this call for segment pairs which they have determined do not intersect (e.g. by an disjoint envelope test).

Implements geos::noding::SegmentIntersector.
