      Description

      Robert Martin has written a paper specifying what could be good OO design quality metrics.

      Implementation of JDepend is based on this paper but a visual representation could be higly more usefull to undertand and interpret metrics. Read the end of Robert's paper to understand how true is it or take a look to the attached image :

      • Each circle represents a java package
      • Circle can have three different colors : green (D is near 0), yellow (D is around 0,2), red (D is around 0,5)
      • Size of circle is proportional to its package size

      The mean of "Distance" metrics could be a good way to compare projects. Projects with a Distance near than 0 are better than projects with a greater Distance (Could be used as a new metric to colorize the treemap).

          The following pages give very good definitions of OO metrics

          Hi all, Isotrol MetricsAnalytics plugin (http://docs.codehaus.org/display/SONAR/Isotrol+MetricsAnalytics) integrates JDepend now. What does we have to do in order to solve this issue (SONAR-94)?

          Removed from Sonar 2.0, afferent couplings do not include calls from external dependencies, so the metric instability is not exact. JDepend has the same limitation.
