onErrorUse

<T extends View> T onErrorUse(Class<T> view)

addAll

void addAll(Collection<? extends Message> message)

add

void add(Message message)

getErrors

List<Message> getErrors()

hasErrors

boolean hasErrors()

onErrorForwardTo

<T> T onErrorForwardTo(Class<T> controller)

Shortcut for

onErrorUse(logic()).forwardTo(controller);

onErrorForwardTo

<T> T onErrorForwardTo(T controller)

Shortcut for

onErrorUse(logic()).forwardTo(controller.getClass());

For usage in the same controller:

validator.onErrorForwardTo(this).someLogic();

onErrorRedirectTo

<T> T onErrorRedirectTo(Class<T> controller)

Shortcut for

onErrorUse(logic()).redirectTo(controller);

onErrorRedirectTo

<T> T onErrorRedirectTo(T controller)

Shortcut for

onErrorUse(logic()).redirectTo(controller.getClass());

For usage in the same controller:

validator.onErrorRedirectTo(this).someLogic();

onErrorUsePageOf

<T> T onErrorUsePageOf(Class<T> controller)

Shortcut for

onErrorUse(page()).of(controller);

onErrorUsePageOf

<T> T onErrorUsePageOf(T controller)

Shortcut for

onErrorUse(page()).of(controller.getClass());

For usage in the same controller:

validator.onErrorUsePageOf(this).someLogic();

onErrorSendBadRequest

void onErrorSendBadRequest()

Shortcut for

onErrorUse(status()).badRequest(errors);

the actual validation errors list will be used.
