/**
* 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
* and one implementor, both set at endpoint creation time.
*
* <p>An endpoint is either in a published or an unpublished state.
* The <code>publish methods can be used to start publishing
* an endpoint, at which point it starts accepting incoming requests.
* Conversely, the <code>stop method can be used to stop
* accepting incoming requests and take the endpoint down.
* Once stopped, an endpoint cannot be published again.
*
* <p>An Executor 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 and
* registering it with the endpoint.
*
* <p>Handler chains can be set using the contained Binding.
*
* <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.
