WebDec 17, 2024 · Method overriding (or inclusion polymorphism) is the ability of a base class to have a method whose implementation varies from one subclass to another. How to Implement Polymorphism in C#. The most common use of polymorphism in C# is through inheritance, where a base class can be inherited by multiple derived classes. You can also … 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. The first formal treatments of subtyping were given by John C. Reynolds in 1980 who used category theory to … See more A simple practical example of subtypes is shown in the diagram. The type "bird" has three subtypes "duck", "cuckoo" and "ostrich". Conceptually, each of these is a variety of the basic … See more Type theorists make a distinction between nominal subtyping, in which only types declared in a certain way may be subtypes of each other, and structural subtyping, in which the structure of two types determines whether or not one is a subtype of the other. … See more If T1 → T2 is a function type, then a subtype of it is any function type S1 → S2 with the property that T1 <: S1 and S2 <: T2. This can be … 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.
