ArrangementDcelHalfedge_2

Definition

A model of the ArrangementDcelHalfedge_2 concept is a halfedge of the Dcel of the arrangement data structure.

An ArrangementDcelHalfedge_2 is not (!) a refinement of the PlanarMapDcelHalfedge_2 concept . However, it is very similar.

The concept has an additional type Base_node which should be the same as the template parameter Base_node of the arrangement (see section reference). It has the additional methods edge_node() and set_edge_node(Base_node*).

The method set_curve should do nothing, i.e. be empty. The function is needed to satisfy a syntactical requirement.

Definition

Operations

Base_node* e.edge_node () returns a pointer to the edge node in the hierarchy tree which holds the curve from which the halfedge was generated.

void e.set_edge_node ( Base_node* b)
sets b to be the edge node in the hierarchy tree which holds the curve of the halfedge.

void e.set_curve ( Curve cv)
should do nothing.
