| NodeMap::container::iterator | nodeIterator () |
| Returns an Iterator over the Nodes in this PlanarGraph. | |
| NodeMap::container::iterator | nodeBegin () |
| NodeMap::container::const_iterator | nodeBegin () const |
| NodeMap::container::iterator | nodeEnd () |
| NodeMap::container::const_iterator | nodeEnd () const |
| void | getNodes (std::vector< Node * > &nodes) |
| Returns the Nodes in this PlanarGraph. | |
| std::vector< DirectedEdge * >::iterator | dirEdgeIterator () |
| Returns an Iterator over the DirectedEdges in this PlanarGraph, in the order in which they were added. | |
| std::vector< DirectedEdge * >::iterator | dirEdgeBegin () |
| std::vector< DirectedEdge * >::iterator | dirEdgeEnd () |
| std::vector< Edge * >::iterator | edgeIterator () |
| Alias for edgeBegin() | |
| std::vector< Edge * >::iterator | edgeBegin () |
| Returns an iterator to first Edge in this graph. | |
| std::vector< Edge * >::iterator | edgeEnd () |
| Returns an iterator to one-past last Edge in this graph. | |
| std::vector< Edge * > * | getEdges () |
| void | remove (Edge *edge) |
| Removes an Edge and its associated DirectedEdges from their from-Nodes and from this PlanarGraph. | |
| void | remove (DirectedEdge *de) |
| Removes DirectedEdge from its from-Node and from this PlanarGraph. | |
| void | remove (Node *node) |
| Removes a node from the graph, along with any associated DirectedEdges and Edges. | |
| std::vector< Node * > * | findNodesOfDegree (std::size_t degree) |
| Returns all Nodes with the given number of Edges around it. The return value is a newly allocated vector of existing nodes. | |
| void | findNodesOfDegree (std::size_t degree, std::vector< Node * > &to) |
| Get all Nodes with the given number of Edges around it. | |

Detailed Description
A planar graph of edges that is analyzed to sew the edges together.
The marked flag on planargraph::Edge and planargraph::Node indicates whether they have been logically deleted from the graph.
