Detailed Description

Finds if two sets of SegmentStrings intersect.

Uses indexing for fast performance and to optimize repeated tests against a target set of lines. Short-circuited to return as soon an intersection is found.

const SegmentSetMutualIntersector* geos::noding::FastSegmentSetIntersectionFinder::getSegmentSetIntersector ( ) const

inline

Gets the segment set intersector used by this class. This allows other uses of the same underlying indexed structure.

Returns

the segment set intersector used
