implementasjonsmønster

Implementasjonsmønster, often translated as "implementation pattern," refers to a reusable solution to a commonly occurring problem within a given context of software development. These patterns are not finalized designs but rather descriptions or templates for how to solve a problem that can be used in many different situations. They are distinct from architectural patterns which deal with higher-level system structures.

The core idea behind implementation patterns is to capture established best practices and wisdom gained from experienced developers. By using these patterns, developers can avoid reinventing the wheel and instead leverage proven solutions, leading to more robust, maintainable, and understandable code. They provide a common vocabulary for developers to discuss design choices.

Examples of implementation patterns include the Singleton pattern, which ensures a class has only one instance, or the Factory Method pattern, which defines an interface for creating an object but lets subclasses decide which class to instantiate. These patterns typically describe the participating classes and objects, their roles, responsibilities, and collaborations. They are often documented in books and online resources, with the Gang of Four's "Design Patterns: Elements of Reusable Object-Oriented Software" being a seminal work in this area. Understanding and applying implementation patterns is a key aspect of object-oriented design and software engineering.
