Inclusion polymorphism
WebFeb 20, 2014 · “Subtyping (or inclusion polymorphism) is a concept wherein a name may denote instances of many different classes as long as they are related by some common superclass. In object-oriented programming, this is often referred to simply as polymorphism.” Let’s make this a bit more explicit with an example. Consider the … WebOct 15, 2024 · The term "inclusion/subtype polymorphism" was introduced later where it was explicitly distinct from ad-hoc polymorphism.

Polymorphism is a Greek word that means "many-shaped" and it has two distinct aspects: At run time, objects of a derived class may be treated as objects of a base class in places such as method parameters and …
WebPolymorphism is an important concept of object-oriented programming. It simply means more than one form. That is, the same entity (function or operator) behaves differently in different scenarios. For example, The + operator in C++ is used to perform two specific functions. When it is used with numbers (integers and floating-point numbers), it ...

In programming language theory, subtyping (also subtype polymorphism or inclusion polymorphism) is a form of type polymorphism in which a subtype is a datatype that is related to another datatype (the supertype) by some notion of substitutability, meaning that program elements, typically subroutines or … See more The notion of subtyping in programming languages dates back to the 1960s; it was introduced in Simula derivatives.

This can be summarised using the following See more In type theory the concept of subsumption is used to define or evaluate whether a type S is a subtype of type T. A type is a set of values. The set can be described extensionally by listing all the values, or it can be described intensionally by stating the … See more Width and depth subtyping Types of records give rise to the concepts of width and depth subtyping. These express two different ways of obtaining a new type of record that allows the same operations as the original record type. Recall that a record … See more Subtyping and inheritance are independent (orthogonal) relationships. They may coincide, but none is a special case of the other.
