    • send

      public ContentResponse send() throws InterruptedException, TimeoutException, 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:
      InterruptedException - if send thread is interrupted

      ExecutionException - if execution fails
      See Also:

    • 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

      listener - the listener that receives response events
