Factory for transport pipes that enables transport pluggability.

 At runtime, on the client side, JAX-WS (more specifically the default PipelineAssembler of JAX-WS client runtime) relies on this factory to create a suitable transport Pipe that can handle the given endpoint address. 
 JAX-WS extensions that provide additional transport support can extend this class and implement the doCreate method. They are expected to check the scheme of the endpoint address (and possibly some other settings from bindings), and create their transport pipe implementations accordingly. For example, 
class MyTransportPipeFactoryImpl {
  Pipe doCreate(...) {
    String scheme = address.getURI().getScheme();
    if(scheme.equals("foo"))
      return new MyTransport(...);
    else
      return null;
  }
}



 TransportPipeFactory look-up follows the standard service discovery mechanism, so you need META-INF/services/com.sun.xml.internal.ws.api.pipe.TransportPipeFactory. 
TODO



One of the JAX-WS operation mode is supposedly where it doesn't have no WSDL whatsoever.
How do we identify the endpoint in such case?

Creates a transport Pipe for the given port, if this factory can do so, or return null. 
Params:
  • context –

     that can be used to determine the pipeline to be assembled.
Throws:

Returns: null to indicate that this factory isn't capable of creating a transport for this port (which causes the caller to search for other TransportPipeFactorys that can. Or non-null.
