 /**

  * Root object that hosts the {@link Packet} processing code

  * at the server.

  *

  * <p>

  * One instance of {@link WSEndpoint} is created for each deployed service

  * endpoint. A hosted service usually handles multiple concurrent

  * requests. To do this efficiently, an endpoint handles incoming

  * {@link Packet} through {@link PipeHead}s, where many copies can be created

  * for each endpoint.

  *

  * <p>

  * Each {@link PipeHead} is thread-unsafe, and request needs to be

  * serialized. A {@link PipeHead} represents a sizable resource

  * (in particular a whole pipeline), so the caller is expected to

  * reuse them and avoid excessive allocations as much as possible.

  * Making {@link PipeHead}s thread-unsafe allow the JAX-WS RI internal to

  * tie thread-local resources to {@link PipeHead}, and reduce the total

  * resource management overhead.

  *

  * <p>

  * To abbreviate this resource management (and for a few other reasons),

  * JAX-WS RI provides {@link Adapter} class. If you are hosting a JAX-WS

  * service, you'll most likely want to send requests to {@link WSEndpoint}

  * through {@link Adapter}.

  *

  * <p>

  * {@link WSEndpoint} is ready to handle {@link Packet}s as soon as

  * it's created. No separate post-initialization step is necessary.

  * However, to comply with the JAX-WS spec requirement, the caller

  * is expected to call the {@link #dispose()} method to allow an

  * orderly shut-down of a hosted service.

  *

  *

  *

  * <h3>Objects Exposed From Endpoint</h3>

  * <p>

  * {@link WSEndpoint} exposes a series of information that represents

  * how an endpoint is configured to host a service. See the getXXX methods

  * for more details.

  *

  *

  *

  * <h3>Implementation Notes</h3>

  * <p>

  * {@link WSEndpoint} owns a {@link WSWebServiceContext} implementation.

  * But a bulk of the work is delegated to {@link WebServiceContextDelegate},

  * which is passed in as a parameter to {@link PipeHead#process(Packet, WebServiceContextDelegate, TransportBackChannel)}.
