default void generateGraph(Graph<V,E> target)
Generate a graph structure.
void generateGraph(Graph<V,E> target, Map<String,T> resultMap)
Generate a graph structure.
• ### Method Detail

• #### generateGraph

void generateGraph(Graph<V,E> target,
Map<String,T> 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.
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
resultMap - if non-null, receives implementation-specific mappings from String roles to graph elements (or collections of graph elements)
Throws:
UnsupportedOperationException - if the graph does not have appropriate vertex and edge suppliers, in order to be able to create new vertices and edges. Methods Graph.getEdgeSupplier() and Graph.getVertexSupplier() must not return null.
