Klassenselektor

KlassenSelektor is a conceptual term used in various programming contexts, particularly within object-oriented programming and systems design. It refers to a mechanism or a piece of code responsible for selecting or instantiating a specific class from a set of available classes based on certain criteria. These criteria can be diverse, ranging from runtime configuration, user input, data type, or a specific state within an application.

The purpose of a KlassenSelektor is to introduce a level of indirection and flexibility into the system. Instead of directly hardcoding which class to use, the KlassenSelektor dynamically determines the appropriate class. This can be beneficial for several reasons, including making the system more extensible, easier to maintain, and adaptable to changing requirements without modifying core logic. For instance, a KlassenSelektor might be employed in a plugin system where different plugins (implemented as separate classes) can be loaded and instantiated at runtime based on user selection or system needs. Another common application is in factory patterns, where a factory class uses a selector to decide which concrete product class to create.

The implementation of a KlassenSelektor can vary widely. It might involve simple conditional logic (if-else statements), lookup tables, or more sophisticated dependency injection frameworks. The key characteristic is its role as a decision-maker for class instantiation, promoting a more modular and adaptable software architecture.
