Detailed Description

An intersector for the red-blue intersection problem.

In this class of line arrangement problem, two disjoint sets of linestrings are provided. It is assumed that within each set, no two linestrings intersect except possibly at their endpoints. Implementations can take advantage of this fact to optimize processing.

Member Function Documentation

process()

virtual void geos::noding::SegmentSetMutualIntersector::process ( SegmentString::ConstVect *  segStrings )

pure virtual

Computes the intersections for two collections of SegmentStrings.

Parameters

segStrings

a collection of SegmentStrings to node

Implemented in geos::noding::MCIndexSegmentSetMutualIntersector.

setBaseSegments()

virtual void geos::noding::SegmentSetMutualIntersector::setBaseSegments ( SegmentString::ConstVect *  segStrings )

pure virtual

Parameters

segStrings

a collection of SegmentStrings to node

Implemented in geos::noding::MCIndexSegmentSetMutualIntersector.

setSegmentIntersector()

void geos::noding::SegmentSetMutualIntersector::setSegmentIntersector ( SegmentIntersector *  si )

inline

Sets the SegmentIntersector to use with this intersector. The SegmentIntersector will either record or add intersection nodes for the input segment strings.

Parameters

si	the segment intersector to use
