Creating a published user parameter within a custom transformer turns that parameter into a parameter in the custom transformer parameter dialog.

• A. True
• B. False
• C. It depends on the parameter
• D. Only for numeric parameters

Answer: (A)

In a Custom Transformer, the public interface is defined by published parameters. When you create a user parameter and publish it, it becomes part of the transformer's parameter dialog so users can configure it each time they place the transformer in a workspace. This makes the transformer reusable and adaptable, since the parameter values can be set without editing the transformer itself. Internal or non-published parameters stay hidden from the dialog, so publishing is exactly what surfaces the parameter.
