NAME

       Analizo::Metric::LackOfCohesionOfMethods - Lack of Cohesion of Methods (LCOM4) metric

DESCRIPTION

       The metric calculation is based on the following article and calculates the cohesion of
       the class.

       Article:

          M. Hitz and B. Montazeri, "Measuring coupling and cohesion in
          object-oriented systems," in Proceedings of the International. Symposium on
          Applied Corporate Computing, 1995.

       The LCOM4 value for a module is the number of connected components of an undirected graph,
       where the nodes are the module's subroutines (methods, functions etc.), and the edges
       indicate that two subroutines use at least one attribute/variable in common, or that one
       subroutines calls the other. These connected components represent independent parts of a
       module, and modules that have more than one of them have independent, distinct
       responsibilities.
