  • Subtyping - Wikipedia
    Subtyping enables a given type to be substituted for another type or abstraction Subtyping is said to establish an is-a relationship between the subtype and some existing abstraction, either implicitly or explicitly, depending on language support
  • oop - What is the difference between subtyping and inheritance in OO . . .
    Subtyping is a key component of OOP - you have an object of one type but which fulfills the interface of another type, so it can be used anywhere the other object could have been used
  • CS 6110 S18 Lecture 24 Subtyping 1 Introduction
    The concept of subtyping is closely tied to inheritance and polymorphism and o ers a formal way of studying them It is best illustrated by means of an example

  • CS153: Compilers Lecture 15: Subtyping - Harvard University
    •Such inclusions give rise to a subtyping hierarchy: •Given any two types T1 and T2, we can calculate their least upper bound (LUB) according to the hierarchy
  • Subtype Polymorphism - Department of Computer Science
    Subtyping was first introduced in SIMULA, considered the first object-oriented programming language Its inventors Ole-Johan Dahl and Kristen Nygaard later went on to win the Turing Award for their contribution to the field of object-oriented programming
