public class DefaultValidationEventHandler

extends Object

implements 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 Unmarshaller and Marshaller.

public boolean handleEvent(ValidationEvent event)

Description copied from interface: ValidationEventHandler

Receive notification of a validation warning or error. The ValidationEvent will have a ValidationEventLocator embedded in it that indicates where the error or warning occurred.

If an unchecked runtime exception is thrown from this method, the JAXB provider will treat it as if the method returned false and interrupt the current unmarshal, validate, or marshal operation.

规范说明:

handleEvent in interface ValidationEventHandler

参数:

event - the encapsulated validation event information. It is a provider error if this parameter is null.

返回:

true if the JAXB Provider should attempt to continue the current unmarshal, validate, or marshal operation after handling this warning/error, false if the provider should terminate the current operation with the appropriate UnmarshalException, ValidationException, or MarshalException.
