public interface FormResult

All FormActions return a FormResult FormResults are lightweight command classes that encode the response to the form These need interpreted by the surrounding framework for example a text message is displayed differently in a web, gui or command line context. Some form results only make sense in a restricted set of contexts. For example the web navigation results. The FormResultVisitor can be extended to handle these additional result types. Functionality can be promoted to additional contexts by replacing these with explicit FormResult sub-classes handled by the FormResultVisitor. By using the visitor pattern we make it easier to identify what FormResult types need to be implemented in each context.
