    • buildResult

      protected abstract T buildResult(HttpRequest request, E entity, ContentType contentType)
      Triggered to generate object that represents a result of request message processing.
      Parameters:
      request - the request message.
      entity - the request entity.
      contentType - the request content type.
      Returns:
      the result of request processing.
    • consumeRequest

      public final void consumeRequest(HttpRequest request, EntityDetails entityDetails, HttpContext httpContext, FutureCallback<T> resultCallback) throws HttpException, IOException
      Description copied from interface: AsyncRequestConsumer
      Triggered to signal receipt of a request message head.
      Specified by:
      consumeRequest in interface AsyncRequestConsumer<T>
      Parameters:
      request - the request message head.
      entityDetails - the request entity details or null if the request does not enclose an entity.
      httpContext - the actual execution context.
      resultCallback - the result callback called when request processing has been completed successfully or unsuccessfully.
      Throws:
      HttpException
      IOException
    • updateCapacity

      public final void updateCapacity(CapacityChannel capacityChannel) throws 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:
      IOException
    • consume

      public final void consume(ByteBuffer src) throws 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:
      IOException
    • streamEnd

      public final void streamEnd(List<? extends Header> trailers) throws HttpException, 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.
      Throws:
      HttpException
      IOException
    • failed

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

      public final void releaseResources()
      Specified by:
      releaseResources in interface ResourceHolder
