| Oct 4, 2017 at 23:05 | comment | added | Frank Hileman | The quoted statement at the top of your question. Assume the class with the instance methods is not polymorphic; i.e. these members are not virtual. "Aggregate any functionality" means put together more than one independent operation or bit of data in the class. | |

| Oct 3, 2017 at 0:22 | comment | added | Frank Hileman | It is easy to prove this statement is incorrect. Suppose a class offers two instance methods that are independent of one another, A and B. An instance of such a class is an object supplying method A, and it is an object supplying method B. As soon as you aggregate any functionality at all, the statement is false. | |
