    • removeValidator

      public void removeValidator​(Validator validator)

    • validators

      public List<Validator> validators()

    • dateFormat

      public void dateFormat​(String pattern, String... attributes)
      Registers date converters (Date -> String -> java.sql.Date) for specified model attributes.

    • dateFormat

      public void dateFormat​(DateFormat format, String... attributes)
      Registers date converters (Date -> String -> java.sql.Date) for specified model attributes.

    • timestampFormat

      public void timestampFormat​(String pattern, String... attributes)

    • timestampFormat

      public void timestampFormat​(DateFormat format, String... attributes)
      Registers timestamp converters (Date -> String -> java.sql.Timestamp) for specified model attributes.

    • convertWith

      public void convertWith​(Converter converter, String... attributes)
      Registers converter for specified model attributes.

    • get

      public Object get​(String attributeName)
      Returns a value of an attribute. The current implementation uses reflection to get to a private or public attribute. Subclasses may override this behavior however they like.
      Specified by:
      get in interface Validatable
      Parameters:
      attributeName - name of attribute. For a standard class it would be an actual name of a field retrievable by reflection.
      Returns:
      value of attribute.

    • addFailedValidator

      public void addFailedValidator​(Validator validator, String errorKey)
      Description copied from interface: Validatable
      This method is not to add validators for future processing. This is instead used to add validators and their respective error messages in case those validators fail.
      Specified by:
      addFailedValidator in interface Validatable
      Parameters:
      validator - validator that failed validation (later to be used to retrieve error message)
      errorKey - - generally an attribute name that failed validation

    • isValid

      public boolean isValid()
      Description copied from interface: Validatable
      Implementation should call {#link validate()} internally.
      Specified by:
      isValid in interface Validatable
      Returns:
      true if object is valid.

    • validate

      public void validate()
      Runs all registered validators and collects errors if any.
      Specified by:
      validate in interface Validatable

    • validate

      public void validate​(boolean reset)
      Runs all registered validators and collects errors if any.
      Specified by:
      validate in interface Validatable
      Parameters:
      reset - true to reset all previous validation errors.

    • errors

      public Errors errors()
      Provides an instance of Errors object, filled with error messages after validation.
      Specified by:
      errors in interface Validatable
      Returns:
      an instance of Errors object, filled with error messages after validation.

    • errors

      public Errors errors​(Locale locale)
      Provides an instance of localized Errors object, filled with error messages after validation.
      Specified by:
      errors in interface Validatable
      Parameters:
      locale - locale.
      Returns:
      an instance of localized Errors object, filled with error messages after validation.
