When you write a wrapper, be aware that:
- The Wrapper_Utilities class (WrapperUtilities in Java™) provides
services to help you with your work. For example, if you run into a problem
with your code, you can use the class's trace_data method. The trace_data
method generates a record that can help you locate and identify the problem.
- You can produce the wrapper in several versions, the first one limited
to basic services, and the subsequent versions progressively more functional
and efficient.
