Class Lattice2DGenerator<T>

  • All Implemented Interfaces:
    NetworkGenerator<T>
    public class Lattice2DGenerator<T>
extends AbstractGenerator<T>
    Generator for n x n lattice where each vertex is incident with its four neighbors except perhaps for the edge vertices depending on whether the lattice is toroidal.

    Based on code from the Jung project.

    • Constructor Detail

      • Lattice2DGenerator

        public Lattice2DGenerator​(boolean isToroidal)
        Creates a Lattice2DGenerator.
        Parameters:
        isToroidal - whether lattice wraps or not.

    • Method Detail

      • createNetwork

        public Network<T> createNetwork​(Network<T> network)
        Given an existing network, add edges to create a 2D lattice. The lattice dimension n is the square root of the number of nodes in the specified network. The resulting lattice will be nxn.
        Parameters:
        network - the network to rewire
        Returns:
        the created network
