2. Template method pattern - Wikipedia

   en.wikipedia.org/wiki/Template_method_pattern

   In object-oriented programming, the template method is one of the behavioral design patterns identified by Gamma et al. [1] in the book Design Patterns.The template method is a method in a superclass, usually an abstract superclass, and defines the skeleton of an operation in terms of a number of high-level steps.

3. Class (computer programming) - Wikipedia

   en.wikipedia.org/wiki/Class_(computer_programming)

   In object-oriented programming, a class defines the shared aspects of objects created from the class. The capabilities of a class differ between programming languages , but generally the shared aspects consist of state ( variables ) and behavior ( methods ) that are each either associated with a particular object or with all objects of that class.

4. Object-oriented analysis and design - Wikipedia

   en.wikipedia.org/wiki/Object-oriented_analysis...

   Object/Class: A tight coupling or association of data structures with the methods or functions that act on the data. This is called a class, or object (an object is created based on a class). Each object serves a separate function. It is defined by its properties, what it is and what it can do.

5. Design Patterns - Wikipedia

   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.

6. Factory method pattern - Wikipedia

   en.wikipedia.org/wiki/Factory_method_pattern

   In object-oriented programming, the factory method pattern is a design pattern that uses factory methods to deal with the problem of creating objects without having to specify their exact classes. Rather than by calling a constructor , this is accomplished by invoking a factory method to create an object.

7. Decorator pattern - Wikipedia

   en.wikipedia.org/wiki/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]

8. Mixin - Wikipedia

   en.wikipedia.org/wiki/Mixin

   Mixins first appeared in Symbolics's object-oriented Flavors system (developed by Howard Cannon), which was an approach to object-orientation used in Lisp Machine Lisp.The name was inspired by Steve's Ice Cream Parlor in Somerville, Massachusetts: [1] The owner of the ice cream shop offered a basic flavor of ice cream (vanilla, chocolate, etc.) and blended in a combination of extra items (nuts ...
