Analizo::Metric::NumberOfPublicAttributes3pm

Overview

The metric calculation is based on the following article and calculates the number of public attributes of a class.

Article: Monitoring of source code metrics in open source projects by Paulo Roberto Miranda Meirelles.

See the adaptation of the paragraph about Number of Public Attributes in the article:

It measures the encapsulation. The attributes of a class must only serve to the functionalities of itself. Thus, good programming practices recommend that the attributes of a class must be manipulated using the access methods (Beck, 1997), the attributes of a class must be private, indicating that the ideal number for this metric is zero.
