Method Detail

getDefaultValidator

default Validator<V> getDefaultValidator()

Returns a validator that checks the state of the Value. This should be overridden for components with internal value conversion or validation, e.g. when the user is providing a string that has to be parsed into a date. An invalid input from user will be exposed to a Binder and can be seen as a validation failure.

Returns:

state validator
