AbstractValidator, CommonsValidator, DateValidator, EditorValidationProxy, EditorValidator, MandatoryValidator, MinMaxValidator, NameValidator, PasswordValidator, PojoCommonsFieldValidator, PojoCommonsValidator, PojoFieldValidator, PojoValidator, RegularExpressionValidator, SetValidator

public interface Validator

An interface describing a validator. The work of the validator will be done in the validate method. If an error is called then an exception will be thrown. Typically the exception will be caught in a panel class such as Page. The handleException method of a ValidationExceptionHandler implementation will then be invoked.
