  - 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,

  - 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()
```
    Description copied from interface: Validatable
    
    Runs validation. Will blow away any previous validation errors.
    
    Specified by:
    
    validate in interface Validatable
  - validate
```
public void validate(boolean reset)
```
    Description copied from interface: Validatable
    
    Runs validation.
    
    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.
