void org::_3pq::jgrapht::generate::RingGraphGenerator::generateGraph ( Graph  target,
VertexFactory  vertexFactory,
Map  resultMap 
) [inline]

Generate a graph structure. The topology of the generated graph is dependent on the implementation. For graphs in which not all vertices share the same automorphism equivalence class, the generator may produce a labeling indicating the roles played by generated elements. This is the purpose of the resultMap parameter. For example, a generator for a wheel graph would designate a hub vertex. Role names used as keys in resultMap should be declared as public static final Strings by implementation classes.

Parameters:
target receives the generated edges and vertices; if this is non-empty on entry, the result will be a disconnected graph since generated elements will not be connected to existing elements
vertexFactory called to produce new vertices
resultMap if non-null, receives implementation-specific mappings from String roles to graph elements (or collections of graph elements)
