Detailed Description

Base class for Noders which make a single pass to find intersections. This allows using a custom SegmentIntersector (which for instance may simply identify intersections, rather than insert them).

Last port: noding/SinglePassNoder.java rev. 1.3 (JTS-1.7)

TODO: Noder inheritance (that's just an interface!)

Member Function Documentation

void geos::noding::SinglePassNoder::computeNodes ( std::vector< SegmentString * > *  segStrings)
overridepure virtual

Computes the noding for a collection of SegmentStrings.

Parameters
segStringsa collection of SegmentStrings to node

Implements geos::noding::Noder.

Implemented in geos::noding::MCIndexNoder, and geos::noding::SimpleNoder.

std::vector<SegmentString*>* geos::noding::SinglePassNoder::getNodedSubstrings ( ) const
overridepure virtual

Returns a Collection of fully noded SegmentStrings. The SegmentStrings have the same context as their parent.

Returns
a Collection of SegmentStrings

Implements geos::noding::Noder.

Implemented in geos::noding::MCIndexNoder, and geos::noding::SimpleNoder.

virtual void geos::noding::SinglePassNoder::setSegmentIntersector ( SegmentIntersector newSegInt)
inlinevirtual

Sets the SegmentIntersector to use with this noder. A SegmentIntersector will normally add intersection nodes to the input segment strings, but it may not - it may simply record the presence of intersections. However, some Noders may require that intersections be added.

Parameters
newSegInt
