Method Detail

convertWith

public void convertWith(Converter converter,
                        String attribute)

Registers converter for specified model attribute.

converterForClass

public <S,T> Converter<S,T> converterForClass(String attribute,
                                                          Class<S> sourceClass,
                                                          Class<T> destinationClass)

Returns converter for specified model attribute, able to convert from sourceClass to destinationClass. Returns null if no suitable converter was found.

converterForValue

public <T> Converter<Object,T> converterForValue(String attribute,
                                                       Object value,
                                                       Class<T> destinationClass)

Returns converter for specified model attribute, able to convert value to an instance of destinationClass. Returns null if no suitable converter was found.

validateWith

public ValidationBuilder validateWith(Validator validator)

validateWith

public ValidationBuilder validateWith(List<Validator> list)

validateNumericalityOf

public NumericValidationBuilder validateNumericalityOf(String... attributes)

validatePresenceOf

public ValidationBuilder validatePresenceOf(String... attributes)

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)

Registers timestamp converters (Date -> String -> java.sql.Timestamp) for specified model attributes.

                            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()

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.
