WebNov 11, 2024 · Polymorphism is a very generic term, which basically just means "the ability of dealing with different types". That is more or less all that is common to all the different types of polymorphism. The most widely-used and most well-known type of polymorphism is probably parametric polymorphism (also sometimes known as generics ). WebThis is called inclusion polymorphism because it allows messages from class c, to be sent to any instance of class sc that is a subtype of c (sc:> c) that has been constrained to c. …
WebThis is a negation of the Inclusion Polymorphism: when operations that are different for all types within the hierarchy require only one member function definition. Thus, Inclusion Polymorphism is: (3rd option) when operations that are identical for all types within the hierarchy require more than one member function definition. WebJun 1, 2014 · Inclusion polymorphism means that an instance of a subtype can be treated as an instance of a supertype. (The Liskov Substitution Principle tells us how to make sure that is safe.)

So, going back to the quote in the book – it is entirely correct, but causes confusion because the author does not distinguish between polymorphism as a general ... WebThe purpose of the type system is to rule out bad programs without ruling out too many good programs. However, once you have subtyping (with a top type) and use it, you get all sorts of situations like looking up an int in a set that holds doubles, not being an error when the set is covariant in the key / value type.
