36/**
37 * A Web service endpoint.
38 *
39 * <p>Endpoints are created using the static methods defined in this
40 * class. An endpoint is always tied to one {@code Binding}
41 * and one implementor, both set at endpoint creation time.
42 *
43 * <p>An endpoint is either in a published or an unpublished state.
44 * The {@code publish} methods can be used to start publishing
45 * an endpoint, at which point it starts accepting incoming requests.
46 * Conversely, the {@code stop} method can be used to stop
47 * accepting incoming requests and take the endpoint down.
48 * Once stopped, an endpoint cannot be published again.
49 *
50 * <p>An {@code Executor} may be set on the endpoint in order
51 * to gain better control over the threads used to dispatch incoming
52 * requests. For instance, thread pooling with certain parameters
53 * can be enabled by creating a {@code ThreadPoolExecutor} and
54 * registering it with the endpoint.
55 *
56 * <p>Handler chains can be set using the contained {@code Binding}.
57 *
58 * <p>An endpoint may have a list of metadata documents, such as WSDL
59 * and XMLSchema documents, bound to it. At publishing time, the
60 * JAX-WS implementation will try to reuse as much of that metadata
61 * as possible instead of generating new ones based on the annotations
62 * present on the implementor.
