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. 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]

4. 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 ...

5. Interaction design pattern - Wikipedia

   en.wikipedia.org/wiki/Interaction_design_pattern

   Interaction design patterns are design patterns applied in the context human-computer interaction, describing common designs for graphical user interfaces. A design pattern is a formal way of documenting a solution to a common design problem. The idea was introduced by the architect Christopher Alexander for use in urban planning and building ...

6. Visitor pattern - Wikipedia

   en.wikipedia.org/wiki/Visitor_pattern

   Overview. The Visitor [1] design pattern is one of the twenty-three well-known Gang of Four design patterns that describe how to solve recurring design problems to design flexible and reusable object-oriented software, that is, objects that are easier to implement, change, test, and reuse.

7. Category:Software design patterns - Wikipedia

   en.wikipedia.org/wiki/Category:Software_design...

   Category. : Software design patterns. A (software) design pattern is a general solution to a common problem in software design. It is a description or template for how to solve a problem, that can be used in different situations. A design pattern typically shows relationship and interaction between classes or objects, without specifying final ...

8. Flyweight pattern - Wikipedia

   en.wikipedia.org/wiki/Flyweight_pattern

   The flyweight pattern is one of twenty-three well-known GoF design patterns. [1] These patterns promote flexible object-oriented software design, which is easier to implement, change, test, and reuse. In other contexts, the idea of sharing data structures is called hash consing . The term was first coined, and the idea extensively explored, by ...

9. 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 ...
