Question: Doc for SOAP UI Pro specific Groovy Properties/Methods

Looking at the groovy script examples (in the online documentation), one sees several methods available that are specific to SOAP UI Pro. For example, the setPropertyValue method. Is there a Javadoc like listing of these methods somewhere on the website (pdf of HTML would work as well) OR are all of the SOAP specific methods documented in the examples provided on this website. I guess I'm wondering what other methods beyond the ones shown might exist and I have not been able to find anything on the website.

Thanks!
Jim
