public abstract boolean handleEvent (ValidationEvent event)

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.

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.

Exceptions:
IllegalArgumentException    if the event object is null.
