org.apache.hc.core5.http.nio.support.BasicResponseConsumer<T>

All Implemented Interfaces:

AsyncDataConsumer, AsyncResponseConsumer<Message<HttpResponse,T>>, ResourceHolder

public class BasicResponseConsumer<T>
extends Object
implements AsyncResponseConsumer<Message<HttpResponse,T>>

Basic implementation of AsyncResponseConsumer that represents response message as a Message and relies on a AsyncEntityConsumer to process response entity stream.

Since:

5.0

Method Details

consumeResponse

public void consumeResponse(HttpResponse response,
 EntityDetails entityDetails,
 HttpContext httpContext,
 FutureCallback<Message<HttpResponse,T>> resultCallback)
                     throws HttpException,
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.

Throws:

HttpException

IOException

informationResponse

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

Description copied from interface: AsyncResponseConsumer

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

Specified by:

informationResponse in interface AsyncResponseConsumer<T>

Parameters:

response - the intermediate (1xx) HTTP response.

httpContext - the actual execution context.

Throws:

HttpException

IOException

updateCapacity

public 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 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 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 void failed(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.

releaseResources

public void releaseResources()

Specified by:

releaseResources in interface ResourceHolder
