Class HttpTransportPipe

  • All Implemented Interfaces:
    Pipe, Tube
    public class HttpTransportPipe
extends AbstractTubeImpl
    Tube that sends a request to a remote HTTP server. TODO: need to create separate HTTP transport pipes for binding. SOAP1.1, SOAP1.2, TODO: XML/HTTP differ in handling status codes.

    • Method Detail

      • processException

        public NextAction processException​(@NotNull
                                   Throwable t)
        Description copied from interface: Tube
        Acts on a exception and performs some clean up operations.

        If a Tube.processRequest(Packet), Tube.processResponse(Packet), Tube.processException(Throwable) throws an exception, this method will be always invoked on all the Tubes in the remaining NextActions.

        On the server side, the Throwable thrown will be propagated to the top-most transport. The transport converts the exception to fault reply or simply logs in case of one-way MEP. If you are a filtering Tube like AbstractTubeImpl, you don't have to override the implementation). On the other hand, any intermediate Tube may want to convert the exception to a fault message.

        On the client side, the Throwable thrown will be propagated all the way back to the calling client applications. (The consequence of that is that if you are a filtering Tube like AbstractTubeImpl, you don't have to override the implementation)

        Returns:
        A NextAction object that represents the next action to be taken by the JAX-WS runtime.

      • processRequest

        public NextAction processRequest​(@NotNull
                                 Packet request)
        Description copied from interface: Tube
        Acts on a request and perform some protocol specific operation. TODO: exception handling semantics need more discussion
        Parameters:
        request - The packet that represents a request message. If the packet has a non-null message, it must be a valid unconsumed Message. This message represents the SOAP message to be sent as a request.

        The packet is also allowed to carry no message, which indicates that this is an output-only request. (that's called "solicit", right? - KK)

        Returns:
        A NextAction object that represents the next action to be taken by the JAX-WS runtime.

      • processResponse

        public NextAction processResponse​(@NotNull
                                  Packet response)
        Description copied from interface: Tube
        Acts on a response and performs some protocol specific operation.

        Once a Tube.processRequest(Packet) is invoked, this method will be always invoked with the response, before this Tube processes another request.

        Parameters:
        response - If the packet has a non-null message, it must be a valid unconsumed Message. This message represents a response to the request message passed to Tube.processRequest(Packet) earlier.

        The packet is also allowed to carry no message, which indicates that there was no response. This is used for things like one-way message and/or one-way transports. TODO: exception handling semantics need more discussion

        Returns:
        A NextAction object that represents the next action to be taken by the JAX-WS runtime.

      • process

        public Packet process​(Packet request)
        Description copied from class: AbstractTubeImpl
        "Dual stack" compatibility mechanism. Allows Tube to be invoked from a Pipe.
        Specified by:
        process in interface Pipe
        Overrides:
        process in class AbstractTubeImpl
        Parameters:
        request - The packet that represents a request message. Must not be null. If the packet has a non-null message, it must be a valid unconsumed Message. This message represents the SOAP message to be sent as a request.

        The packet is also allowed to carry no message, which indicates that this is an output-only request. (that's called "solicit", right? - KK)

        Returns:
        The packet that represents a response message. Must not be null. If the packet has a non-null message, it must be a valid unconsumed Message. This message represents a response to the request message passed as a parameter.

        The packet is also allowed to carry no message, which indicates that there was no response. This is used for things like one-way message and/or one-way transports.

      • preDestroy

        public void preDestroy()
        Description copied from interface: Tube
        Invoked before the last copy of the pipeline is about to be discarded, to give Tubes a chance to clean up any resources.

        This can be used to invoke PreDestroy lifecycle methods on user handler. The invocation of it is optional on the client side, but mandatory on the server side.

        When multiple copies of pipelines are created, this method is called only on one of them.

      • copy

        public HttpTransportPipe copy​(TubeCloner cloner)
        Description copied from interface: Tube
        Creates an identical clone of this Tube.

        This method creates an identical pipeline that can be used concurrently with this pipeline. When the caller of a pipeline is multi-threaded and need concurrent use of the same pipeline, it can do so by creating copies through this method.

        Implementation Note

        It is the implementation's responsibility to call TubeCloner.add(Tube,Tube) to register the copied pipe with the original. This is required before you start copying the other Tube references you have, or else there's a risk of infinite recursion.

        For most Tube implementations that delegate to another Tube, this method requires that you also copy the Tube that you delegate to.

        For limited number of Tubes that do not maintain any thread unsafe resource, it is allowed to simply return this from this method (notice that even if you are stateless, if you got a delegating Tube and that one isn't stateless, you still have to copy yourself.)

        Note that this method might be invoked by one thread while another thread is executing the other process method. See the Codec.copy() for more discussion about this.

        Specified by:
        copy in interface Tube
        Specified by:
        copy in class AbstractTubeImpl
        Parameters:
        cloner - Use this object (in particular its TubeCloner.copy(Tube) method to clone other pipe references you have in your pipe. See TubeCloner for more discussion about why.
        Returns:
        always non-null Tube.
