| /** |
| * A basic event handler interface for validation errors. |
| * |
| * <p> |
| * If an application needs to implement customized event handling, it must |
| * implement this interface and then register it with either the |
| * {@link Unmarshaller#setEventHandler(ValidationEventHandler) Unmarshaller}, |
| * the {@link Validator#setEventHandler(ValidationEventHandler) Validator}, or |
| * the {@link Marshaller#setEventHandler(ValidationEventHandler) Marshaller}. |
| * The JAXB Provider will then report validation errors and warnings encountered |
| * during the unmarshal, marshal, and validate operations to these event |
| * handlers. |
| * |
| * <p> |
| * If the <tt>handleEvent</tt> method throws an unchecked runtime exception, |
| * the JAXB Provider must treat that as if the method returned false, effectively |
| * terminating whatever operation was in progress at the time (unmarshal, |
| * validate, or marshal). |
| * |
| * <p> |
| * Modifying the Java content tree within your event handler is undefined |
| * by the specification and may result in unexpected behaviour. |
| * |
| * <p> |
| * Failing to return false from the <tt>handleEvent</tt> method after |
| * encountering a fatal error is undefined by the specification and may result |
| * in unexpected behavior. |
