<div class="textblock"><p>Represents a directed graph which is embeddable in a planar surface. </p>
|
|
<p>This class and the other classes in this package serve as a framework for building planar graphs for specific algorithms. This class must be subclassed to expose appropriate methods to construct the graph. This allows controlling the types of graph components (<a class="el" href="classgeos_1_1planargraph_1_1DirectedEdge.html" title="Represents a directed edge in a PlanarGraph. ">DirectedEdge</a>, <a class="el" href="classgeos_1_1planargraph_1_1Edge.html" title="Represents an undirected edge of a PlanarGraph. ">Edge</a> and <a class="el" href="classgeos_1_1planargraph_1_1Node.html" title="A node in a PlanarGraph is a location where 0 or more Edge meet. ">Node</a>) which can be added to the graph. An application which uses the graph framework will almost always provide subclasses for one or more graph components, which hold application-specific data and graph algorithms. </p>
