      • vertices

        public SimpleWeightedGraphMatrixGenerator<V,​E> vertices​(java.util.List<V> vertices)
        Set the generator vertices.
        Parameters:
        vertices - the graph vertices
        Returns:
        the generator

      • weights

        public SimpleWeightedGraphMatrixGenerator<V,​E> weights​(double[][] weights)
        Set the weights of the generator.
        Parameters:
        weights - the weights
        Returns:
        the generator

      • generateGraph

        public void generateGraph​(Graph<V,​E> target,
                          java.util.Map<java.lang.String,​V> resultMap)
        Description copied from interface: GraphGenerator
        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
        resultMap - if non-null, receives implementation-specific mappings from String roles to graph elements (or collections of graph elements)
