Description: The Multiton design pattern is a variation of the Singleton pattern that restricts the creation of instances of a class to a limited number, where each instance is associated with a unique key. This pattern is particularly useful in situations where access to shared resources needs to be controlled or where a specific state must be maintained for different contexts. Unlike the Singleton, which allows only one instance of a class, the Multiton allows multiple instances, but each one is identified by a key that acts as an identifier. This means that while multiple instances can be created, each one is unique and can be accessed through its corresponding key. This pattern is ideal for managing configurations, database connections, or any other resource that needs to be shared among different parts of an application but requires isolation based on its context. Implementing the Multiton pattern can help improve efficiency and code organization by facilitating instance management and avoiding unnecessary object creation. In summary, the Multiton is an effective solution for situations where precise control over the creation and access to class instances is required, ensuring that each instance is unique and easily accessible through its key.
