2. Design Patterns - Wikipedia

   en.wikipedia.org/wiki/Design_Patterns

   Design Patterns: Elements of Reusable Object-Oriented Software (1994) is a software engineering book describing software design patterns. The book was written by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides, with a foreword by Grady Booch. The book is divided into two parts, with the first two chapters exploring the capabilities ...

3. Software design pattern - Wikipedia

   en.wikipedia.org/wiki/Software_design_pattern

   Software design pattern. In software engineering, a design pattern describes a relatively small, well-defined aspect (i.e. functionality) of a computer program in terms of how to write the code . Using a pattern is intended to leverage an existing concept rather than re-inventing it.

4. Design pattern - Wikipedia

   en.wikipedia.org/wiki/Design_pattern

   Design pattern. A design pattern is the re-usable form of a solution to a design problem. The idea was introduced by the architect Christopher Alexander [1] and has been adapted for various other disciplines, particularly software engineering. [2]

5. Decorator pattern - Wikipedia

   en.wikipedia.org/wiki/Decorator_pattern

   Decorator pattern. In object-oriented programming, the decorator pattern is a design pattern that allows behavior to be added to an individual object, dynamically, without affecting the behavior of other instances of the same class. [1] The decorator pattern is often useful for adhering to the Single Responsibility Principle, as it allows ...

6. Memento pattern - Wikipedia

   en.wikipedia.org/wiki/Memento_pattern

   The memento pattern is a software design pattern that exposes the private internal state of an object. One example of how this can be used is to restore an object to its previous state (undo via rollback), another is versioning, another is custom serialization. The memento pattern is implemented with three objects: the originator, a caretaker ...

7. Facade pattern - Wikipedia

   en.wikipedia.org/wiki/Facade_pattern

   Facade pattern. The facade pattern (also spelled façade) is a software design pattern commonly used in object-oriented programming. Analogous to a façade in architecture, it is an object that serves as a front-facing interface masking more complex underlying or structural code. A facade can: improve the readability and usability of a software ...

8. Builder pattern - Wikipedia

   en.wikipedia.org/wiki/Builder_pattern

   Builder pattern. The builder pattern is a design pattern designed to provide a flexible solution to various object creation problems in object-oriented programming. The intent of the builder design pattern is to separate the construction of a complex object from its representation. It is one of the Gang of Four design patterns .
