Public Member Functions | |
| virtual IThing * | getIThing ()=0 |
| Return an IThing interface for this object. | |
| virtual const IThing * | getIThing () const =0 |
| Return a const IThing interface for this object. | |
| virtual IGeomPoint * | getPoint (uint32 end)=0 |
| Returns a pointer to the IGeomPoint associated with end 0 or 1. Returns 0 if end > 1. May be null if the edge is currently invalid. | |
| virtual const IGeomPoint * | getPoint (uint32 end) const =0 |
| Returns a pointer to the IGeomPoint associated with end 0 or 1. Returns 0 if end > 1. May be null if the edge is currently invalid. | |
| virtual void | setPoint (IGeomPoint *point, uint32 end)=0 |
| virtual bool | isValid () const =0 |
| Returns true if the edge is currently valid, that is if both ends (0 and 1) are assigned to a non-null IGeomPoint object. | |
| virtual bool | isFake () const =0 |
| Returns true if the edge is fake meaning that the edge exists and valid but user should not be able to see and interact with it. | |
| virtual DVect | getCentroid () const =0 |
| Returns the centroid of the edge. | |
| virtual double | getLength () const =0 |
| Returns the distance between the two IGeomPoint objects, return 0.0 if not valid. | |
| virtual DVect | getDirection () const =0 |
| Returns the unit vector from end 0 to end 1. Returns DVect(0) if not valid. | |
| virtual DVect | getVector () const =0 |
| Returns the vector from end 0 to end 1. Return DVect(0) if not valid. | |
| virtual DVect | getClosestPoint (const DVect &pos) const =0 |
| Returns the point on the edge closes to the point pos. Returns DVect(0) if not valid. | |
| virtual CLinkType< IGeomEdge > | getNext (uint32 end) const =0 |
| Returns an interface to a CLinkType<> object, a const pointer to the next object in the linked list. | |
| virtual LinkType< IGeomEdge > | getNext (uint32 end)=0 |
| Returns an interface to a LinkType<> object, a pointer to the next object in the linked list. | |
| virtual CLinkType< IGeomPoly > | getStart () const =0 |
| Returns an interface to a CLinkType<> object, a const pointer to the first object in the linked list. | |
| virtual LinkType< IGeomPoly > | getStart ()=0 |
| Returns an interface to a LinkType<> object, a pointer to the first object in the linked list. | |
| virtual int | getPolyOrder () const =0 |
| Returns number of polygon faces attached. | |
| virtual const GeomBase * | getGeomBase () const =0 |
| Return const GeomBase. | |
| virtual DVect | convertToGlobal (double u) const =0 |
| Convert to global coordinate the point on edge. If u = 0.0 it will be position of point(0), if u=1.0 – position of point(1). Returns zero vector if edge is not valid. | |
| virtual double | convertToLocal (const DVect &pos) const =0 |
| Convert o local edge coordinate. | |
Static Public Attributes | |
| static const TType | type_ = 0x4c815bcc |
| The type identification number for this class, for use in convert_cast() and convert_getcast(). | |

Sets the point associated with end 0 or 1, has no effect if end > 1. point may be null, rendering the edge invalid. This will cause an edgeMoved signal in the containing IGeomSet, if applicable.
