| ) | [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::computeIM | ( | geom::IntersectionMatrix & | im | ) | [inline, virtual] |
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 bool geos::geomgraph::Edge::equals | ( | const Edge & | e | ) | const [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
| virtual int geos::geomgraph::Edge::getDepthDelta | ( | ) | const [inline, virtual] |
The depthDelta is the change in depth as an edge is crossed from R to L.
