Detailed Description

Nodes a set of SegmentStrings by performing a brute-force comparison of every segment to every other one.

This has n^2 performance, so is too slow for use on large numbers of segments.

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

overridevirtual

Computes the noding for a collection of SegmentStrings.

Parameters

segStrings

a collection of SegmentStrings to node

Implements geos::noding::SinglePassNoder.

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

inlineoverridevirtual

Returns a Collection of fully noded SegmentStrings.

The SegmentStrings have the same context as their parent.

Returns

a Collection of SegmentStrings
