- All Implemented Interfaces:
AsyncDataConsumer
,AsyncResponseConsumer<Message<HttpResponse,T>>
,ResourceHolder
public class BasicResponseConsumer<T> extends java.lang.Object implements AsyncResponseConsumer<Message<HttpResponse,T>>
Basic implementation ofAsyncResponseConsumer
that represents response message as aMessage
and relies on aAsyncEntityConsumer
to process response entity stream.- Since:

Method Detail

consumeResponse
public void consumeResponse(HttpResponse response, EntityDetails entityDetails, HttpContext httpContext, FutureCallback<Message<HttpResponse,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 interfaceAsyncResponseConsumer<T>
- Parameters:
response
- the response message head.entityDetails
- the response entity details ornull
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
java.io.IOException
-
informationResponse
public void informationResponse(HttpResponse response, HttpContext httpContext) throws HttpException, java.io.IOException
Description copied from interface:AsyncResponseConsumer
Triggered to signal receipt of an intermediate (1xx) HTTP response.- Specified by:
informationResponse
in interfaceAsyncResponseConsumer<T>
- Parameters:
response
- the intermediate (1xx) HTTP response.httpContext
- the actual execution context.- Throws:
HttpException
java.io.IOException
-
updateCapacity
public 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 interfaceAsyncDataConsumer
- Parameters:
capacityChannel
- the channel for capacity updates.- Throws:
java.io.IOException
-
consume
public 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 interfaceAsyncDataConsumer
- Parameters:
src
- data source.- Throws:
java.io.IOException
-
streamEnd
public 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 interfaceAsyncDataConsumer
- Parameters:
trailers
- data stream trailers.- Throws:
HttpException
java.io.IOException
-
failed
public void failed(java.lang.Exception cause)
Description copied from interface:AsyncResponseConsumer
Triggered to signal a failure in data processing.- Specified by:
failed
in interfaceAsyncResponseConsumer<T>
- Parameters:
cause
- the cause of the failure.
-
releaseResources
public void releaseResources()
