How would you implement a singleton pattern in Avaloq Script?

The implementation of a singleton pattern aims to ensure that a class has only one instance throughout the application's lifecycle and provides a global point of access to that instance. This concept is crucial in scenarios where having multiple instances might lead to resource conflicts or inconsistencies, such as when managing shared resources or configurations.

In Avaloq Script, to implement the singleton pattern, one would typically use a private constructor to prevent other classes from creating new instances directly. Instead, a static method or property would then be provided that checks if an instance already exists. If it does, that instance is returned, ensuring that no additional instances are created. This method promotes both controlled access to the instance and ensures that no more than one instance exists.

By focusing on ensuring there is only one instance and providing a way to globally access it, the singleton pattern serves its purpose effectively, making it the correct choice for this question.
