konstruktionsdesignmönster

Konstruktionsdesignmönster, often referred to as creational design patterns, are a category of design patterns used in software engineering that focus on object creation mechanisms. These patterns aim to find flexible and reusable ways to create objects. Instead of using direct instantiation with the `new` operator, creational patterns delegate this responsibility to other objects or methods. This separation of concerns helps to decouple the client code from the concrete classes it needs to instantiate, leading to more maintainable and adaptable software.

The primary goal of creational patterns is to control the instantiation process of objects. They provide mechanisms to create objects in a manner that suits the specific situation, often by abstracting the instantiation logic. This abstraction allows for variations in how objects are created, when they are created, and by whom they are created. By separating the knowledge of how an object is created from the code that uses the object, the system becomes less dependent on specific implementations.

Common examples of creational design patterns include the Singleton pattern, which ensures a class has only one instance and provides a global point of access to it; the Factory Method pattern, which defines an interface for creating an object but lets subclasses decide which class to instantiate; and the Abstract Factory pattern, which provides an interface for creating families of related or dependent objects without specifying their concrete classes. These patterns, among others, offer solutions to recurring design problems related to object creation, promoting better software design.
