Interface FormValidator

public interface FormValidator

Interface that can be implemented by an ActionProvider or the formBean that is used by an ActionProvider . A FormValidator is used for contextual validation, e.g. to verify that one value is greater than the other or that two given passwords match. For all other basic validations, use JSR-380 (Bean Validtion 2.0) annotations.
The validate()-method is being called before the ActionProviders perform-method. Only if there are no errors (see FieldProcessor.hasErrors()), the ActionProvider is being actually called.
