Encapsulation (computer programming) In software systems, encapsulation refers to the bundling of data with the mechanisms or methods that operate on the data. It may also refer to the limiting of direct access to some of that data, such as an object's components. [ 1] Essentially, encapsulation prevents external code from being concerned with ...
C# (/ ˌ s iː ˈ ʃ ɑːr p / see SHARP) [b] is a general-purpose high-level programming language supporting multiple paradigms. C# encompasses static typing, [16]: 4 strong typing, lexically scoped, imperative, declarative, functional, generic, [16]: 22 object-oriented (class-based), and component-oriented programming disciplines. [17]
In class-based, object-oriented programming, a constructor (abbreviation: ctor) is a special type of function called to create an object. It prepares the new object for use, often accepting arguments that the constructor uses to set required member variables . A constructor resembles an instance method, but it differs from a method in that it ...
Encapsulation is the computer-networking process of concatenating layer-specific headers or trailers with a service data unit (i.e. a payload) for transmitting information over computer networks. [2] [3] [4] Deencapsulation (or de-encapsulation) is the reverse computer-networking process for receiving information; it removes from the protocol ...
Coupling (computer programming) In software engineering, coupling is the degree of interdependence between software modules; a measure of how closely connected two routines or modules are; [1] the strength of the relationships between modules. [2] Coupling isn't binary but it's multi-dimensional. [3] Coupling is usually contrasted with cohesion.
Abstraction (computer science) In software engineering and computer science, abstraction is the process of generalizing concrete details, [ 1] such as attributes, away from the study of objects and systems to focus attention on details of greater importance. [ 2] Abstraction is a fundamental concept in computer science and software engineering ...
Mutator method. In computer science, a mutator method is a method used to control changes to a variable. They are also widely known as setter methods. Often a setter is accompanied by a getter, which returns the value of the private member variable. They are also known collectively as accessors .
This allows C#, unlike Java, to support objects with encapsulation that are not reference types. In Java, compound types are synonymous with reference types; methods cannot be defined for a type unless it is also a class reference type. In C# the concepts of encapsulation and methods have been decoupled from the reference requirement so that a ...
