    29  * A basic event handler interface for validation errors.

    30  *

    31  * <p>

    32  * If an application needs to implement customized event handling, it must

    33  * implement this interface and then register it with either the

    34  * {@link Unmarshaller#setEventHandler(ValidationEventHandler) Unmarshaller},

    35  * the {@link Validator#setEventHandler(ValidationEventHandler) Validator}, or

    36  * the {@link Marshaller#setEventHandler(ValidationEventHandler) Marshaller}.

    37  * The JAXB Provider will then report validation errors and warnings encountered

    38  * during the unmarshal, marshal, and validate operations to these event

    39  * handlers.

    40  *

    41  * <p>

    42  * If the <tt>handleEvent</tt> method throws an unchecked runtime exception,

    43  * the JAXB Provider must treat that as if the method returned false, effectively

    44  * terminating whatever operation was in progress at the time (unmarshal,

    45  * validate, or marshal).

    46  *

    47  * <p>

    48  * Modifying the Java content tree within your event handler is undefined

    49  * by the specification and may result in unexpected behaviour.

    50  *

    51  * <p>

    52  * Failing to return false from the <tt>handleEvent</tt> method after

    53  * encountering a fatal error is undefined by the specification and may result

    54  * in unexpected behavior.

    55  *

    56  * <p>
