A node in a PlanarGraph is a location where 0 or more Edges meet. A node is connected to each of its incident Edges via an outgoing DirectedEdge. Some clients using a PlanarGraph may want to subclass Node to add their own application-specific data and methods. More...

Detailed Description

A node in a PlanarGraph is a location where 0 or more Edges meet. A node is connected to each of its incident Edges via an outgoing DirectedEdge. Some clients using a PlanarGraph may want to subclass Node to add their own application-specific data and methods.
