022/**
023 * Represents the options available when shutting down routes.
024 * <p/>
025 * Is used for example to defer shutting down a route until all inflight exchanges have
026 * been completed, after which the route can be shutdown safely.
027 * <p/>
028 * This allows fine grained configuration in accomplishing graceful shutdown where you
029 * have for example some internal route which other routes are dependent upon.
030 * <ul>
031 *   <li>Default - The <b>default</b> behavior where a route will attempt to shutdown now</li>
032 *   <li>Defer - Will defer shutting down the route and let it be active during graceful shutdown.
033 *               The route will be shutdown at a later stage during the graceful shutdown process.</li>
