Method Details

getServerView

public static GroupValidator getServerView(GroupValidator gv)

Wraps the GroupValidator so that only validations are visible that are active on the server. This way client-only validations are ignored.

getClientView

public static GroupValidator getClientView(GroupValidator gv)

Wraps the GroupValidator so that only validations are visible that are active on the client. This way server-only validations are ignored.

isMandatory

public static boolean isMandatory(Iterable<Validator> iter)

Tells if the field is mandatory (not 'blank').

Takes only conditionless, error-level validators into account.

Parameters:

iter - An iteratable, for example a ValidatorGroup or a List.

Returns:

True if the field is mandatory.

getNumberRange

public static Number[] getNumberRange(Iterable<Validator> iter)

allowNegativeNumber

public static boolean allowNegativeNumber(Iterable<Validator> iter)

getLengthRange

public static Integer[] getLengthRange(Iterable<Validator> iter)

getPostPointDigits

public static Optional<Integer> getPostPointDigits(Iterable<Validator> iter)

getPrePointDigits

public static Optional<Integer> getPrePointDigits(Iterable<Validator> iter)

getTextLength

public static Optional<Integer> getTextLength(GroupValidator validator)

getRegExps

public static Pattern[] getRegExps(Iterable<Validator> iter)
