    KsDp library

    Description

    Design Patterns Library: contains a group elements of reusable Object Oriented Software. It is an attempt to combine implementations of: Gang of Four (GoF), GRASP, IoC.

    This library is divided into four main categories, which are described below

    Integration:

    • IoC Inversion of Control inverts the flow of control as compared to traditional control flow.
    • DI Dependency Injection is a technique in which an object receives other objects that it depends on.
    • LS Service Locator pattern is a design pattern used in software development to encapsulate the processes involved in obtaining a service with a strong abstraction layer.

    Creational: Creational patterns are ones that create objects, rather than having to instantiate objects directly. This gives the program more flexibility in deciding which objects need to be created for a given case.

    • Abstract factory groups object factories that have a common theme.
    • Builder constructs complex objects by separating construction and representation.
    • Factory method creates objects without specifying the exact class to create.
    • Prototype creates objects by cloning an existing object.
    • Singleton restricts object creation for a class to only one instance.

    Structural: These concern class and object composition. They use inheritance to compose interfaces and define ways to compose objects to obtain new functionality.

    • Adapter allows classes with incompatible interfaces to work together by wrapping its own interface around that of an already existing class.
    • Bridge decouples an abstraction from its implementation so that the two can vary independently.
    • Composite composes zero-or-more similar objects so that they can be manipulated as one object.
    • Decorator dynamically adds/overrides behaviour in an existing method of an object.
    • Facade provides a simplified interface to a large body of code.
    • Flyweight reduces the cost of creating and manipulating a large number of similar objects.
    • Proxy provides a placeholder for another object to control access, reduce cost, and reduce complexity.

    Behavioral: Most of these design patterns are specifically concerned with communication between objects.

    • Chain of responsibility delegates commands to a chain of processing objects.
    • Command creates objects that encapsulate actions and parameters.
    • Interpreter implements a specialized language.
    • Iterator accesses the elements of an object sequentially without exposing its underlying representation.
    • Mediator allows loose coupling between classes by being the only class that has detailed knowledge of their methods.
    • Memento provides the ability to restore an object to its previous state (undo).
    • Observer is a publish/subscribe pattern, which allows a number of observer objects to see an event.
    • State allows an object to alter its behavior when its internal state changes.
    • Strategy allows one of a family of algorithms to be selected on-the-fly at runtime.
    • Template method defines the skeleton of an algorithm as an abstract class, allowing its subclasses to provide concrete behavior.
    • Visitor separates an algorithm from an object structure by moving the hierarchy of methods into one object.
