        Description copied from interface: Request

        Tags this request with the given metadata tag.

        This is particularly useful in proxies, where requests for the same origin but from different clients may be tagged with client's metadata (e.g. the client remote address).

        The tag metadata class must correctly implement Object.hashCode() and Object.equals(Object) so that it can be used, along with the origin, to identify a destination.

        tag in interface Request

        tag - the metadata to tag the request with
        Returns:

        When resources are pushed from the server, the given listener is invoked for every pushed resource. The parameters to the BiFunction are this request and the synthesized request for the pushed resource. The BiFunction should return a CompleteListener that may also implement other listener interfaces to be notified of various response events, or null to signal that the pushed resource should be canceled.

      • send

        public ContentResponse send()

                            java.util.concurrent.TimeoutException,
                            java.util.concurrent.ExecutionException
        Description copied from interface: Request
        Sends this request and returns the response.

        This method should be used when a simple blocking semantic is needed, and when it is known that the response content can be buffered without exceeding memory constraints.

        For example, this method is not appropriate to download big files from a server; consider using Request.send(Response.CompleteListener) instead, passing your own Response.Listener or a utility listener such as InputStreamResponseListener.

        The method returns when the complete event is fired.

        Specified by:
        send in interface Request
        Returns:
        a ContentResponse for this request
        Throws:
        java.lang.InterruptedException - if send thread is interrupted
        java.util.concurrent.TimeoutException - if send times out
        java.util.concurrent.ExecutionException - if execution fails
        See Also:
        Response.CompleteListener.onComplete(Result)

      • send

        public void send​(Response.CompleteListener listener)
        Description copied from interface: Request

        Sends this request and asynchronously notifies the given listener for response events.

        This method should be used when the application needs to be notified of the various response events as they happen, or when the application needs to efficiently manage the response content.

        The listener passed to this method may implement not only Response.CompleteListener but also other response listener interfaces, and all the events implemented will be notified. This allows application code to write a single listener class to handle all relevant events.

        Specified by:
        send in interface Request
        Parameters:
        listener - the listener that receives response events
