 Public Member Functions inherited from geos::planargraph::DirectedEdge | |
| DirectedEdge (Node *newFrom, Node *newTo, const geom::Coordinate &directionPt, bool newEdgeDirection) | |
Constructs a DirectedEdge connecting the from node to the to node. | |
| Edge * | getEdge () const |
| Returns this DirectedEdge's parent Edge, or null if it has none. | |
| void | setEdge (Edge *newParentEdge) |
| Associates this DirectedEdge with an Edge (possibly null, indicating no associated Edge). | |
| int | getQuadrant () const |
| Returns 0, 1, 2, or 3, indicating the quadrant in which this DirectedEdge's orientation lies. | |
| const geom::Coordinate & | getDirectionPt () const |
| Returns a point to which an imaginary line is drawn from the from-node to specify this DirectedEdge's orientation. | |
| bool | getEdgeDirection () const |
| Returns whether the direction of the parent Edge (if any) is the same as that of this Directed Edge. | |
| Node * | getFromNode () const |
| Returns the node from which this DirectedEdge leaves. | |
| Node * | getToNode () const |
| Returns the node to which this DirectedEdge goes. | |
| geom::Coordinate & | getCoordinate () const |
| Returns the coordinate of the from-node. | |
| double | getAngle () const |
| Returns the angle that the start of this DirectedEdge makes with the positive x-axis, in radians. | |
| DirectedEdge * | getSym () const |
| Returns the symmetric DirectedEdge – the other DirectedEdge associated with this DirectedEdge's parent Edge. | |
| void | setSym (DirectedEdge *newSym) |
| Sets this DirectedEdge's symmetric DirectedEdge, which runs in the opposite direction. | |
| int | compareTo (const DirectedEdge *obj) const |
| Returns 1 if this DirectedEdge has a greater angle with the positive x-axis than b", 0 if the DirectedEdges are collinear, and -1 otherwise. | |
| int | compareDirection (const DirectedEdge *e) const |
| Returns 1 if this DirectedEdge has a greater angle with the positive x-axis than b", 0 if the DirectedEdges are collinear, and -1 otherwise. | |
| std::string | print () const |
| Prints a detailed string representation of this DirectedEdge to the given PrintStream. | |
| Public Member Functions inherited from geos::planargraph::GraphComponent | |
| virtual bool | isVisited () const |
| Tests if a component has been visited during the course of a graph algorithm. | |
| virtual void | setVisited (bool p_isVisited) |
| Sets the visited flag for this component. | |
| virtual bool | isMarked () const |
| Tests if a component has been marked at some point during the processing involving this graph. | |
| virtual void | setMarked (bool p_isMarked) |
| Sets the marked flag for this component. | |
