Class Metrics<V extends GraphIONode,E>

java.lang.Object
  bcds.phison.cmd.Metrics<V,E>

public class Metrics<V extends GraphIONode,E>
extends java.lang.Object

Computes one or more metrics on one or more topologies. The metrics are loaded dynamically, based on a list of class names provided by the user. The metric+topology is considered a computation unit and several such computation units (threads) are spawn (the user can limit the number of concurrent threads).

Any class that implements from GraphMetric can be loaded dynamically, provided that it operates on the target element (graph, node or link). Not all the metrics are applicable to all the targets. For example, Density can only be applied to the whole graph and not to node or link. Moreover, it is also important to notice that only the graph target element is compatible with more than one topology as a parameter.

Alternatively, this command/class can be used to display information about the a GraphMetric derived class (see parameter -d). An example of use of this program follows, assuming that a Unix-like shell is used:

   (cat <<END
   Metrics.float_fmt="%.10f"
   Metrics.nw=10
   END
   ) | java -jar phison.jar Metrics -env_file=- -metrics=Assortativity,\
            AvgPathLength,ClusteringCoeff,Diameter,OutNodeDegree,\
                   EdgeSetSize,AvgTwoTermReliability \
            -target=graph \
            net1.sgf net2.net netN.sgf
 

See the output of --help for a description of parameters and operation.
