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 ...
Anonymous function. In computer programming, an anonymous function ( function literal, lambda abstraction, lambda function, lambda expression or block) is a function definition that is not bound to an identifier. Anonymous functions are often arguments being passed to higher-order functions or used for constructing the result of a higher-order ...
High-level programming language. In computer science, a high-level programming language is a programming language with strong abstraction from the details of the computer. In contrast to low-level programming languages, it may use natural language elements, be easier to use, or may automate (or even hide entirely) significant areas of computing ...
Abstract syntax tree. An abstract syntax tree ( AST) is a data structure used in computer science to represent the structure of a program or code snippet. It is a tree representation of the abstract syntactic structure of text (often source code) written in a formal language. Each node of the tree denotes a construct occurring in the text.
Set (abstract data type) In computer science, a set is an abstract data type that can store unique values, without any particular order. It is a computer implementation of the mathematical concept of a finite set. Unlike most other collection types, rather than retrieving a specific element from a set, one typically tests a value for membership ...
Abstract data type. In computer science, an abstract data type ( ADT) is a mathematical model for data types, defined by its behavior ( semantics) from the point of view of a user of the data, specifically in terms of possible values, possible operations on data of this type, and the behavior of these operations.
Bridge pattern. The bridge pattern is a design pattern used in software engineering that is meant to "decouple an abstraction from its implementation so that the two can vary independently", introduced by the Gang of Four. [ 1] The bridge uses encapsulation, aggregation, and can use inheritance to separate responsibilities into different classes .
The abstract factory pattern in software engineering is a design pattern that provides a way to create families of related objects without imposing their concrete classes, by encapsulating a group of individual factories that have a common theme without specifying their concrete classes. [ 1] According to this pattern, a client software ...
