Description copied from class: ExpressionAsker

Build an expression interactively in the wizard, i.e. user picks what attribute to use, how to transform it, etc.

Overrides:

askInteractively in class ExpressionAsker

ask

public nz.org.riskscape.problem.ResultOrProblems<nz.org.riskscape.wizard.Answer.Response> ask(AskRequest input)

Description copied from class: BaseAsker

Get a bound value from the user - note that the response's original input is returned from BaseAsker.askUnbound(AskRequest). This is partly here because the original API exposed this method on the interface, and keeping this method here keeps the refactoring/change noise down to a minimum while allowing the interface to change in the way we want to preserve the right amount of encapsulation

Overrides:

ask in class ExpressionAsker
