                                          FutureCallback<T> resultCallback)
                                   throws HttpException,
                                          java.io.IOException
        Description copied from interface: AsyncResponseConsumer
        Triggered to signal receipt of a response message head.
        Specified by:
        consumeResponse in interface AsyncResponseConsumer<T>
        Parameters:
        response - the response message head.
        entityDetails - the response entity details or null if the response does not enclose an entity.
        httpContext - the actual execution context.
        resultCallback - the result callback called when response processing has been completed successfully or unsuccessfully.

      • updateCapacity

        public final void updateCapacity​(CapacityChannel capacityChannel)
                                  throws java.io.IOException
        Description copied from interface: AsyncDataConsumer
        Triggered to signal ability of the underlying data stream to receive data capacity update. The data consumer can choose to write data immediately inside the call or asynchronously at some later point.
        Specified by:
        updateCapacity in interface AsyncDataConsumer
        Parameters:
        capacityChannel - the channel for capacity updates.
        Throws:
        java.io.IOException
      • consume

        public final void consume​(java.nio.ByteBuffer src)
                           throws java.io.IOException
        Description copied from interface: AsyncDataConsumer
        Triggered to pass incoming data to the data consumer. The consumer must consume the entire content of the data buffer. The consumer must stop incrementing its capacity on the capacity channel if it is unable to accept more data. Once the data consumer has handled accumulated data or allocated more intermediate storage it can update its capacity information on the capacity channel.
        Specified by:
        consume in interface AsyncDataConsumer
        Parameters:
        src - data source.
        Throws:
        java.io.IOException
      • streamEnd

        public final void streamEnd​(java.util.List<? extends Header> trailers)
                             throws HttpException,
                                    java.io.IOException
        Description copied from interface: AsyncDataConsumer
        Triggered to signal termination of the data stream.
        Specified by:
        streamEnd in interface AsyncDataConsumer
        Parameters:
        trailers - data stream trailers.

        public final void failed​(java.lang.Exception cause)
        Description copied from interface: AsyncResponseConsumer
        Triggered to signal a failure in data processing.
        Specified by:
        failed in interface AsyncResponseConsumer<T>
        Parameters:
        cause - the cause of the failure.
