Examples of javax.xml.bind.ValidationEventHandler

javax.xml.bind.ValidationEventHandler

An instance of ValidationEventHandler allows to customize the reply to instances of {@link javax.xml.bind.ValidationEvent}. By default, there is a standard ValidationEventHandler, converting errors and fatal errors in Exceptions.

The JAXB user creates instances of ValidationEventHandler and registers them with the {@link Marshaller}, {@link Unmarshaller}, or {@link Validator}. The JAXB provider is required not to throw exceptions directly, but to convert all detected problems into events, which are fired on the ValidationEventHandler.
