Detailed Description

Nodes a set of SegmentString using a index based on MonotoneChain and a SpatialIndex.

The SpatialIndex used should be something that supports envelope (range) queries efficiently (such as a Quadtree or STRtree).

Member Function Documentation

void geos::noding::MCIndexNoder::computeNodes ( std::vector< SegmentString * > *  segStrings)
overridevirtual

Computes the noding for a collection of SegmentStrings.

Parameters
segStringsa collection of SegmentStrings to node

Implements geos::noding::SinglePassNoder.

std::vector<SegmentString*>* geos::noding::MCIndexNoder::getNodedSubstrings ( ) const
overridevirtual

Returns a Collection of fully noded SegmentStrings.

The SegmentStrings have the same context as their parent.

Returns
a Collection of SegmentStrings

Implements geos::noding::SinglePassNoder.
