ohair@286 37 * Factory for transport pipes that enables transport pluggability.
ohair@286 38 *
ohair@286 39 * <p>
ohair@286 40 * At runtime, on the client side, JAX-WS (more specifically the default {@link PipelineAssembler}
ohair@286 41 * of JAX-WS client runtime) relies on this factory to create a suitable transport {@link Pipe}
ohair@286 42 * that can handle the given {@link EndpointAddress endpoint address}.
ohair@286 43 *
ohair@286 44 * <p>
ohair@286 45 * JAX-WS extensions that provide additional transport support can
ohair@286 46 * extend this class and implement the {@link #doCreate} method.
ohair@286 47 * They are expected to check the scheme of the endpoint address
ohair@286 48 * (and possibly some other settings from bindings), and create
ohair@286 49 * their transport pipe implementations accordingly.
ohair@286 50 * For example,
ohair@286 51 *
ohair@286 52 * <pre>
ohair@286 53 * class MyTransportPipeFactoryImpl {
ohair@286 54 * Pipe doCreate(...) {
ohair@286 55 * String scheme = address.getURI().getScheme();
ohair@286 56 * if(scheme.equals("foo"))
ohair@286 57 * return new MyTransport(...);
ohair@286 58 * else
ohair@286 59 * return null;
ohair@286 60 * }
ohair@286 61 * }
ohair@286 62 * </pre>
ohair@286 63 *
ohair@286 64 * <p>
ohair@286 65 * {@link TransportPipeFactory} look-up follows the standard service
ohair@286 66 * discovery mechanism, so you need
ohair@286 67 * {@code META-INF/services/com.sun.xml.internal.ws.api.pipe.TransportPipeFactory}.
ohair@286 68 *
ohair@286 69 *
ohair@286 70 *
ohair@286 71 * <h2>TODO</h2>
ohair@286 72 * <p>
ohair@286 73 * One of the JAX-WS operation mode is supposedly where it doesn't have no WSDL whatsoever.
ohair@286 74 * How do we identify the endpoint in such case?
