An object en of the class Edge_node is a node holding an edge curve in the hierarchy tree.

In addition to the operations of Subcurve_node the following operation is implemented.


bool en.is_edge_node () returns true;

Halfedge_handle en.halfedge () returns the halfedge in the planar map that corresponds to the X_curve in en. The returned halfedge has the same direction as the x-curve cv in en (i.e., its source vertex holds the point that is the source of cv, and its target vertex holds the point that is cv's target.)
