/**

 * A Web service endpoint.

 *

 * <p>Endpoints are created using the static methods defined in this

 * class. An endpoint is always tied to one <code>Binding</code>

 * and one implementor, both set at endpoint creation time.

 *

 * <p>An endpoint is either in a published or an unpublished state.

 * The <code>publish</code> methods can be used to start publishing

 * an endpoint, at which point it starts accepting incoming requests.

 * Conversely, the <code>stop</code> method can be used to stop

 * accepting incoming requests and take the endpoint down.

 * Once stopped, an endpoint cannot be published again.

 *

 * <p>An <code>Executor</code> may be set on the endpoint in order

 * to gain better control over the threads used to dispatch incoming

 * requests. For instance, thread pooling with certain parameters

 * can be enabled by creating a <code>ThreadPoolExecutor</code> and

 * registering it with the endpoint.

 *

 * <p>Handler chains can be set using the contained <code>Binding</code>.

 *

 * <p>An endpoint may have a list of metadata documents, such as WSDL

 * and XMLSchema documents, bound to it. At publishing time, the

 * JAX-WS implementation will try to reuse as much of that metadata

 * as possible instead of generating new ones based on the annotations

 * present on the implementor.
