Classes
		__builtin__.object Clustering   class Clustering(__builtin__.object)     Implements a class that cluterizes nodes of Graph objects   Methods to cluterize Graphs using ClusteringStopCondition object and ClusteringSimilarityFunction object     Methods defined here: __init__(self) cluster_graph(self, graph_to_cluster=None, clustered_graph_generator=None, similarity_function=None, stop_condition=None) Method that clusters a given Graph graph_to_cluster   Returns the clustered graph    "graph to cluster": a graph witch we want to cluster   "clustered_graph_generator" is a Class that returns an empty GraphCluster (or a child class) when called with get_new_graph_cluster()    -> this allows the user to control which kind of GraphCluster is going to use   "similarity_function": a ClusteringSimilarityFunction object   "stop_condition": a ClusteringStopCondition object initialize_from_graph(self, graph_to_cluster=None, clustered_graph_generator=None) Initializes the GraphCluster from a Graph object "graph"   Taking as input a graph, object, creates a cluster graph with one node attribute per cluster. This cluster graph object is then clusterized with method cluster_graph()   "graph_to_cluster": graph to transform to a GraphCluster object Data and other attributes defined here: __dict__ = <dictproxy object> dictionary for instance variables (if defined) __weakref__ = <attribute '__weakref__' of 'Clustering' objects> list of weak references to the object (if defined)
