	DirectedEdgeStar ()
	Constructs a DirectedEdgeStar with no edges.

void	add (DirectedEdge *de)

void	remove (DirectedEdge *de)
	Drops a member of this DirectedEdgeStar.

std::vector< DirectedEdge * >::iterator	iterator ()
	Returns an Iterator over the DirectedEdges, in ascending order by angle with the positive x-axis.

std::vector< DirectedEdge * >::iterator	begin ()
	Returns an iterator to first DirectedEdge.

std::vector< DirectedEdge * >::iterator	end ()
	Returns an iterator to one-past last DirectedEdge.

std::vector< DirectedEdge * >::const_iterator	begin () const
	Returns an const_iterator to first DirectedEdge.

std::vector< DirectedEdge * >::const_iterator	end () const
	Returns an const_iterator to one-past last DirectedEdge.

std::size_t	getDegree () const
	Returns the number of edges around the Node associated with this DirectedEdgeStar.

geom::Coordinate &	getCoordinate () const
	Returns the coordinate for the node at wich this star is based.

std::vector< DirectedEdge * > &	getEdges ()
	Returns the DirectedEdges, in ascending order by angle with the positive x-axis.

int	getIndex (const Edge *edge)
	Returns the zero-based index of the given Edge, after sorting in ascending order by angle with the positive x-axis.

int	getIndex (const DirectedEdge *dirEdge)
	Returns the zero-based index of the given DirectedEdge, after sorting in ascending order by angle with the positive x-axis.

unsigned int	getIndex (int i) const
	Returns the remainder when i is divided by the number of edges in this DirectedEdgeStar.

DirectedEdge *	getNextEdge (DirectedEdge *dirEdge)
	Returns the DirectedEdge on the left-hand side of the given DirectedEdge (which must be a member of this DirectedEdgeStar).
