Detailed Description

Detects invalid coverage topology where ring segments interact. The inputs to processIntersections(SegmentString, int, SegmentString, int)} must be CoverageRing s. If an invalid situation is detected the input target segment is marked invalid using CoverageRing::markInvalid(int).

This class assumes it is used with SegmentSetMutualIntersector, so that segments in the same ring are not evaluated.

Constructor & Destructor Documentation

◆ InvalidSegmentDetector()

geos::coverage::InvalidSegmentDetector::InvalidSegmentDetector ( )

inline

Creates an invalid segment detector.

Member Function Documentation

◆ isDone()

bool geos::coverage::InvalidSegmentDetector::isDone ( ) const

inlineoverridevirtual

Reports whether the client of this class needs to continue testing all intersections in an arrangement.

Returns: true if there is not need to continue testing segments

The default implementation always return false (process all intersections).

Reimplemented from geos::noding::SegmentIntersector.

◆ processIntersections()

void geos::coverage::InvalidSegmentDetector::processIntersections	(	SegmentString *	ssAdj,
		std::size_t	iAdj,
		SegmentString *	ssTarget,
		std::size_t	iTarget
	)

overridevirtual

Process interacting segments. The input order is important. The adjacent segment is first, the target is second. The inputs must be CoverageRing.

Implements geos::noding::SegmentIntersector.
