## Class DefaultValidationEventHandler

- java.lang.Object
- - javax.xml.bind.helpers.DefaultValidationEventHandler

- All Implemented Interfaces:
    ValidationEventHandler

      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`.

  Since:
    JAXB1.0

    `Unmarshaller`, `Validator`, `ValidationEventHandler`

          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.

      Specified by:
        `handleEvent` in interface `ValidationEventHandler`
      Parameters:
        `event` - the encapsulated validation event information. It is a provider error if this parameter is null.
      Returns:
        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`.
