GraphGenerator<V,E,V>
public class CompleteGraphGenerator<V,E> extends java.lang.Object implements GraphGenerator<V,E,V>
Generates a complete graph of any size. A complete graph is a graph where every vertex shares an edge with every other vertex. If it is a directed graph, then edges must always exist in both directions. On a side note, a complete graph is the least efficient possible graph in terms of memory and cpu usage. Note: This contructor was designed for a simple undirected or directed graph. It will act strangely when used with certain graph types, such as undirected multigraphs. Note, though, that a complete undirected multigraph is rather senseless -- you can keep adding edges and the graph is never truly complete.- Since:

generateGraph
public void generateGraph(Graph<V,E> target, VertexFactory<V> vertexFactory, java.util.Map<java.lang.String,V> resultMap)
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.- Specified by:

- 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 elementsvertexFactory
- called to produce new verticesresultMap
- if non-null, receives implementation-specific mappings from String roles to graph elements (or collections of graph elements)
