virtual void geos::geomgraph::Edge::addIntersection	(	algorithm::LineIntersector *	li,
		size_t	segmentIndex,
		size_t	geomIndex,
		size_t	intIndex
	)

virtual

Add an EdgeIntersection for intersection intIndex.

An intersection that falls exactly on a vertex of the edge is normalized to use the higher of the two possible segmentIndexes

virtual void geos::geomgraph::Edge::addIntersections	(	algorithm::LineIntersector *	li,
		size_t	segmentIndex,
		size_t	geomIndex
	)

virtual

Adds EdgeIntersections for one or both intersections found for a segment of an edge to the edge intersection list.

void geos::geomgraph::Edge::computeIM ( geom::IntersectionMatrix & im )

inlineoverridevirtual

Update the IM with the contribution for this component.

A component only contributes if it has a labelling for both parent geometries

Implements geos::geomgraph::GraphComponent.

virtual

equals is defined to be:

e1 equals e2 iff the coordinates of e1 are the same or the reverse of the coordinates in e2
