aoqi@0 33 * The PreDestroy annotation is used on methods as a callback notification to
aoqi@0 34 * signal that the instance is in the process of being removed by the
aoqi@0 35 * container. The method annotated with PreDestroy is typically used to
aoqi@0 36 * release resources that it has been holding. This annotation MUST be
aoqi@0 37 * supported by all container managed objects that support PostConstruct
aoqi@0 38 * except the application client container in Java EE 5. The method on which
aoqi@0 39 * the PreDestroy annotation is applied MUST fulfill all of the following
aoqi@0 40 * criteria:
aoqi@0 41 * <p>
aoqi@0 42 * <ul>
aoqi@0 43 * <li>The method MUST NOT have any parameters except in the case of
aoqi@0 44 * interceptors in which case it takes an InvocationContext object as
aoqi@0 45 * defined by the Interceptors specification.</li>
aoqi@0 46 * <li>The method defined on an interceptor class MUST HAVE one of the
aoqi@0 47 * following signatures:
aoqi@0 48 * <p>
aoqi@0 49 * void &#060;METHOD&#062;(InvocationContext)
aoqi@0 50 * <p>
aoqi@0 51 * Object &#060;METHOD&#062;(InvocationContext) throws Exception
aoqi@0 52 * <p>
aoqi@0 53 * <i>Note: A PreDestroy interceptor method must not throw application
aoqi@0 54 * exceptions, but it may be declared to throw checked exceptions including
aoqi@0 55 * the java.lang.Exception if the same interceptor method interposes on
aoqi@0 56 * business or timeout methods in addition to lifecycle events. If a
aoqi@0 57 * PreDestroy interceptor method returns a value, it is ignored by
aoqi@0 58 * the container.</i>
aoqi@0 59 * </li>
aoqi@0 60 * <li>The method defined on a non-interceptor class MUST HAVE the
aoqi@0 61 * following signature:
aoqi@0 62 * <p>
aoqi@0 63 * void &#060;METHOD&#062;()
aoqi@0 64 * </li>
aoqi@0 65 * <li>The method on which PreDestroy is applied MAY be public, protected,
aoqi@0 66 * package private or private.</li>
aoqi@0 67 * <li>The method MUST NOT be static.</li>
aoqi@0 68 * <li>The method MAY be final.</li>
aoqi@0 69 * <li>If the method throws an unchecked exception it is ignored except in the
aoqi@0 70 * case of EJBs where the EJB can handle exceptions.</li>
aoqi@0 71 * </ul>
