Class AskAs<T>

java.lang.Object

nz.org.riskscape.wizard.AskAs<T>

public class AskAs<T>
extends Object

An AskAs is a way for a Question to signal to the UI that it can ask the question in a customized way, but ultimately the survey wants the answer to be recorded in a way that can be bound to the Question's parameter type. This allows a user-friendly experience for certain options while being able to still allow a more complex, custom value to be edited in "expert mode" scenarios (such as editing an ini file, or switching a GUI in to expert mode)

NB at the moment, ask as questions are assumed to always be composite, as they are the only examples we've seen so far. There's no reason for it to need to be this way, but it was simpler at the time.
