Method Detail

generateGraph

public void generateGraph(Graph<V,E> target,
                 VertexFactory<V> vertexFactory,
                 Map<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:

generateGraph in interface GraphGenerator<V,E,V>

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)
