geos::operation::buffer::RightmostEdgeFinder Class Reference

A RightmostEdgeFinder find the geomgraph::DirectedEdge in a list which has the highest coordinate, and which is oriented L to R at that point. (I.e. the right side is on the RHS of the edge.) More...

Constructor & Destructor Documentation

geos::operation::buffer::RightmostEdgeFinder::RightmostEdgeFinder

(

)

A RightmostEdgeFinder finds the geomgraph::DirectedEdge with the rightmost coordinate.

The geomgraph::DirectedEdge returned is guaranteed to have the R of the world on its RHS.
