NAME

       Analizo::Metric::NumberOfChildren - Number of Children (NOC) metric

DESCRIPTION

       The metric calculation is based on the following article and calculates the number of immediate
       subclasses subordinate to a class in the hierarchy.

       Article: Software Quality Metrics for Object-Oriented Environments by Linda H. Rosenberg and Lawrence E.
       Hyatt.

       See the paragraph about Number of Children in the article:

       The number of children is the number of immediate subclasses subordinate to a class in the hierarchy. It
       is an indicator of the potential influence a class can have on the design and on the system. The greater
       the number of children, the greater the likelihood of improper abstraction of the parent and may be a
       case of misuse of subclassing. But the greater the number of children, the greater the reusability since
       inheritance is a form of reuse. If a class has a large number of children, it may require more testing of
       the methods of that class, thus increase the testing time.
