static int	depthFactor (int currLocation, int nextLocation)
	Computes the factor for the change in depth when moving from one location to another. E.g. if crossing from the INTERIOR to the EXTERIOR the depth decreases, so the factor is -1.

Detailed Description

A directed EdgeEnd.

Member Function Documentation

◆ getSym()

DirectedEdge * geos::geomgraph::DirectedEdge::getSym ( )

Each Edge gives rise to a pair of symmetric DirectedEdges, in opposite directions.

Returns: the DirectedEdge for the same Edge but in the opposite direction

◆ isInteriorAreaEdge()

bool geos::geomgraph::DirectedEdge::isInteriorAreaEdge ( )

Tells wheter this edge is an Area.

This is an interior Area edge if

its label is an Area label for both Geometries
and for each Geometry both sides are in the interior.

Returns: true if this is an interior Area edge

◆ isLineEdge()

bool geos::geomgraph::DirectedEdge::isLineEdge ( )

Tells wheter this edge is a Line.

This edge is a line edge if

at least one of the labels is a line label
any labels which are not line labels have all Locations = EXTERIOR

◆ print()

virtual std::string geos::geomgraph::DirectedEdge::print ( ) const

virtual

Reimplemented from geos::geomgraph::EdgeEnd.

◆ setEdgeDepths()

void geos::geomgraph::DirectedEdge::setEdgeDepths	(	int	position,
		int	newDepth )

Set both edge depths.

One depth for a given side is provided. The other is computed depending on the Location transition and the depthDelta of the edge.

◆ setVisitedEdge()

void geos::geomgraph::DirectedEdge::setVisitedEdge ( bool newIsVisited )

Marks both DirectedEdges attached to a given Edge.

This is used for edges corresponding to lines, which will only appear oriented in a single direction in the result.
