  1. The MOOD Metrics Suite

  2. Number of Methods Inherited • In order to determine the number of methods inherited, the Software Engineer must do the following, • Obtain the class to be processed and parent classes CRC cards. • Pick a method in the parent class and check to see if it is also defined in the the new class. • If so, add one. • Repeat until all methods have been processed. • Enter number into cell.

  3. Number of Methods • In order to determine the number of methods, the Software Engineer must do the following, • Obtain the current classes CRC card. • Count the number of methods. • Input count into cell.

  4. Number of New Methods • In order to determine the number of new methods, the Software Engineer must do the following, • Obtain the class to be processed and parent classes CRC cards. • Pick a method in the parent class and check to see if it is also defined in the the new class. • If not, add one. • Repeat until all methods have been processed. • Enter number into cell.

  5. Formula for Calculations • SI = [NOO X level/ Mtotal • Specialization index X degree of specalization / Total # of Methods • MIF = S Mi(Ci) / S Ma(Ci) • Method Inheritance Factor = sum number of methods inherited / sum number of methods • MIF = S Mo(Ci) / S Mn(Ci) X DC(Ci) • Method Inheritance Factor = sum number of overriding methods / sum number of new methods X descendents count
