How is a custom exception class created in Avaloq Script?

Creating a custom exception class in Avaloq Script involves extending the built-in Exception class. By doing so, developers can define specific types of errors that are relevant to their application's context, which enhances error handling and improves the clarity of error messages.

When you extend the built-in Exception class, you can add custom attributes or methods that pertain to the exception's context. This allows your exceptions to carry more information about the circumstances under which they were thrown and can also enable specialized handling for different types of errors.

This approach is advantageous because it makes your code more maintainable and understandable, particularly in larger systems where it is common to encounter various error conditions. Using a hierarchy of exception classes can help categorize and manage different error types in a structured manner, making error handling cleaner and more robust.

Other options, such as using a function like "createException" or a predefined interface, do not represent the standard way of creating custom exceptions in Avaloq Script. Implementing a behavior model also does not directly relate to the creation of custom exceptions. Each of those alternatives lacks the specificity and clarity offered by extending the Exception class.
