Package org.jgrapht.generate

Class HyperCubeGraphGenerator<V,​E>

  • Type Parameters:
    V - the graph vertex type
    E - the graph edge type
    All Implemented Interfaces:
    GraphGenerator<V,​E,​V>
    public class HyperCubeGraphGenerator<V,​E>
extends Object
implements GraphGenerator<V,​E,​V>
    Generates a hyper cube graph of any size. This is a graph that can be represented by bit strings, so for an n-dimensional hypercube each vertex resembles an n-length bit string. Then, two vertices are adjacent if and only if their bitstring differ by exactly one element.

        public void generateGraph​(Graph<V,​E> target,
                          Map<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)
