Detailed Description
Creates a single OverlayEdge.
Member Function Documentation
◆ addCoordinates()
| void geos::operation::overlayng::OverlayEdge::addCoordinates | ( | CoordinateSequence * | coords | ) | const |
Adds the coordinates of this edge to the given list, in the direction of the edge. Duplicate coordinates are removed (which means that this is safe to use for a path of connected edges in the topology graph).
- Parameters
-
coords the coordinate list to add to
References geos::edgegraph::HalfEdge::sym().
◆ directionPt()
|
inlineoverridevirtual |
Gets the direction point of this edge. In the base case this is the dest coordinate of the edge. Subclasses may override to allow a HalfEdge to represent an edge with more than two coordinates.
- Returns
- the direction point for the edge
