Detailed Description

Computes all intersections between segments in a set of SegmentString.

Intersections found are represented as SegmentNodes and added to the SegmentStrings in which they occur. As a final step in the noding a new set of segment strings split at the nodes may be returned.

Last port: noding/Noder.java rev. 1.8 (JTS-1.7)

TODO: this was really an interface, we should avoid making it a Base class

Member Function Documentation

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

pure virtual

Computes the noding for a collection of SegmentStrings.

Some Noders may add all these nodes to the input SegmentStrings; others may only add some or none at all.

Parameters

segStrings

a collection of SegmentStrings to node The caller remains responsible for releasing the memory associated with the container and its elements.

Implemented in geos::noding::snapround::SnapRoundingNoder, geos::noding::IteratedNoder, geos::noding::snap::SnappingNoder, geos::noding::MCIndexNoder, geos::noding::snapround::MCIndexSnapRounder, geos::noding::ScaledNoder, geos::noding::SinglePassNoder, geos::noding::ValidatingNoder, and geos::noding::SimpleNoder.

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

pure virtual

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

Returns

a newly allocated std::vector of newly allocated SegmentStrings (copies of input, if needs be). Caller is responsible to delete container and elements.

Implemented in geos::noding::snapround::SnapRoundingNoder, geos::noding::snap::SnappingNoder, geos::noding::IteratedNoder, geos::noding::MCIndexNoder, geos::noding::SinglePassNoder, geos::noding::snapround::MCIndexSnapRounder, geos::noding::ScaledNoder, geos::noding::ValidatingNoder, and geos::noding::SimpleNoder.
