Method is Used by only One Subclass (MUOS)

Description:

MUOS detects if the behavior of a superclass is relevant only for one of its subclasses. It is then suggested to move it to that subclass.

Example:

In the following example, the message getQuota is declared by Employee but it is sent to Salesman objects only.

   class Employee {
       int getQuota() { return quota; }
       ...
       // getQuota() is not used by Employee
   }

   class Salesman extends Employee {
       void f() {
           int quota = getQuota();
       }
   }

   class Engineer extends Employee {
       void f(Salesman s) {
           int quota = s.getQuota();
       }
   }
