Uses of QuadEdge in Jcg.triangulations2D

Methods in Jcg.triangulations2D that return QuadEdge

Modifier and Type	Method and Description
static QuadEdge	QuadEdge.connect(QuadEdge e1, QuadEdge e2) Creates a new QuadEdge that connects e1.dest() to e2.orig()
QuadEdge	QuadEdge.dual() Returns the dual QuadEdge, oriented at 90 degrees in direct order
QuadEdge	QuadEdge.dualSym() Returns the symmetric of the dual QuadEdge (which is also the dual of the symmetric QuadEdge).
QuadEdge	QuadEdge.lnext() Returns the next QuadEdge along the left cycle (lnext.orig() == this.dest())
QuadEdge	QuadEdge.lprev() Returns the previous QuadEdge along the left cycle (lprev.dest() == this.orig())
static QuadEdge	QuadEdge.makeEdge(Point_2 orig, Point_2 dest) Creates a new QuadEdge, setting next and dual fields to default null values.
QuadEdge	QuadEdge.next() Returns the next QuadEdge starting at orig() in direct order
QuadEdge	QuadEdge.prev() Returns the previous QuadEdge starting at orig() in direct order
QuadEdge	QuadEdge.rnext() Returns the next QuadEdge along the right cycle (rnext.orig() == this.dest())
QuadEdge	QuadEdge.rprev() Returns the previous QuadEdge along the right cycle (rprev.dest() == this.orig())
QuadEdge	QuadEdge.sym() Returns the symmetric QuadEdge, with origin and destination reversed.

Methods in Jcg.triangulations2D with parameters of type QuadEdge

Modifier and Type	Method and Description
static QuadEdge	QuadEdge.connect(QuadEdge e1, QuadEdge e2) Creates a new QuadEdge that connects e1.dest() to e2.orig()
static void	QuadEdge.deleteEdge(QuadEdge q) Deletes a QuadEdge, that is, disconnects it from its cycle (same for its dual and its symmetric).
static void	QuadEdge.flipEdge(QuadEdge e) Performs a flip of QuadEdge e.
void	QuadEdge.setDual(QuadEdge dual) sets dual QuadEdge.
void	QuadEdge.setNext(QuadEdge next) Sets next QuadEdge starting from orig() in direct order.
static void	QuadEdge.splice(QuadEdge a, QuadEdge b) Merges/splits umbrella around q1.orig() with umbrella around q2.orig().
