bool getForced() const
Returns, whether the HalfEdge belongs to a constrained edge or not.
Definition HalfEdge.h:101
bool mForced
True, if the HalfEdge belongs to a constrained edge, false otherwise.
Definition HalfEdge.h:42
int getNext() const
Returns the number of the next HalfEdge.
Definition HalfEdge.h:86
void setNext(int n)
Sets the number of the next HalfEdge.
Definition HalfEdge.h:111
void setPoint(int p)
Sets the number of point at which this HalfEdge points.
Definition HalfEdge.h:116
