   javax.xml.bind.helpers.DefaultValidationEventHandler

All Implemented Interfaces:
ValidationEventHandler

JAXB 1.0 only default validation event handler. This is the default handler for all objects created from a JAXBContext that is managing schema-derived code generated by a JAXB 1.0 binding compiler.

This handler causes the unmarshal and validate operations to fail on the first error or fatal error.

This handler is not the default handler for JAXB mapped classes following JAXB 2.0 or later versions. Default validation event handling has changed and is specified in javax.xml.bind.Unmarshaller and javax.xml.bind.Marshaller .
