Method Detail

blockWaiting

public ClassicHttpResponse blockWaiting()
                                 throws IOException,
                                        InterruptedException

Throws:

IOException

InterruptedException

consumeResponse

public void consumeResponse(HttpResponse asyncResponse,
                            EntityDetails entityDetails,
                            HttpContext context,
                            FutureCallback<Void> resultCallback)
                     throws HttpException,
                            IOException

Description copied from interface: AsyncResponseConsumer

Triggered to signal receipt of a response message head.

Specified by:

consumeResponse in interface AsyncResponseConsumer<Void>

Parameters:

asyncResponse - the response message head.

entityDetails - the response entity details or null if the response does not enclose an entity.

context - the actual execution context.

resultCallback - the result callback called when response processing has been completed successfully or unsuccessfully.

Throws:

HttpException - in case of an HTTP protocol violation.

IOException - in case of an I/O error.

informationResponse

public void informationResponse(HttpResponse response,
                                HttpContext context)
                         throws HttpException,
                                IOException

Description copied from interface: AsyncResponseConsumer

Triggered to signal receipt of an intermediate (1xx) HTTP response.

Specified by:

informationResponse in interface AsyncResponseConsumer<Void>

Parameters:

response - the intermediate (1xx) HTTP response.

context - the actual execution context.

Throws:

HttpException - in case of an HTTP protocol violation.

IOException - in case of an I/O error.

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 - in case of an I/O error.

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 - in case of an I/O error.

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 - in case of an HTTP protocol violation.

IOException - in case of an I/O error.

failed

public final void failed(Exception cause)

Description copied from interface: AsyncResponseConsumer

Triggered to signal a failure in data processing.

Specified by:

failed in interface AsyncResponseConsumer<Void>

Parameters:

cause - the cause of the failure.

releaseResources

public void releaseResources()

Specified by:

releaseResources in interface ResourceHolder
