- - ### Method Detail

    - #### verticesToGenerateEdgesFor

          public CommunityGenerator.Builder verticesToGenerateEdgesFor(Iterable<Vertex> vertices)

    - #### expectedNumCommunities

          public CommunityGenerator.Builder expectedNumCommunities(int expectedNumCommunities)

    - #### expectedNumEdges

          public CommunityGenerator.Builder expectedNumEdges(int expectedNumEdges)

    - #### communityDistribution

          public CommunityGenerator.Builder communityDistribution(Distribution community)

      Sets the distribution to be used to generate the sizes of communities.

    - #### degreeDistribution

          public CommunityGenerator.Builder degreeDistribution(Distribution degree)

      Sets the distribution to be used to generate the out-degrees of vertices.

    - #### crossCommunityPercentage

          public CommunityGenerator.Builder crossCommunityPercentage(double percentage)

      Sets the percentage of edges that cross a community, i.e. connect a vertex to a vertex in another community. The lower this value, the higher the modularity of the generated communities.
      Parameters:
        `percentage` - Percentage of community crossing edges. Must be in [0,1]

    - #### create

          public CommunityGenerator create()
