Detailed Description
A directed EdgeEnd.
Member Function Documentation
◆ getSym()
|
inline |
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 whether 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 whether 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()
|
overridevirtual |
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.
