Method Detail

onResponseReceived

protected void onResponseReceived(HttpResponse response)
                           throws java.io.IOException

Description copied from class: AbstractAsyncResponseConsumer

Invoked when a HTTP response message is received. Please note that the AbstractAsyncResponseConsumer.onContentReceived(ContentDecoder, IOControl) method will be invoked only if the response messages has a content entity enclosed.

Specified by:

onResponseReceived in class AbstractAsyncResponseConsumer<HttpResponse>

Parameters:

response - HTTP response message.

Throws:

java.io.IOException - in case of an I/O error

onEntityEnclosed

protected void onEntityEnclosed(HttpEntity entity,
                                ContentType contentType)
                         throws java.io.IOException

Description copied from class: AbstractAsyncResponseConsumer

Invoked if the response message encloses a content entity.

Specified by:

onEntityEnclosed in class AbstractAsyncResponseConsumer<HttpResponse>

Parameters:

entity - HTTP entity

contentType - expected content type.

Throws:

java.io.IOException - in case of an I/O error

onContentReceived

protected void onContentReceived(ContentDecoder decoder,
                                 IOControl ioControl)
                          throws java.io.IOException

Description copied from class: AbstractAsyncResponseConsumer

Invoked to process a chunk of content from the ContentDecoder. The IOControl interface can be used to suspend input events if the consumer is temporarily unable to consume more content.

The consumer can use the ContentDecoder.isCompleted() method to find out whether or not the message content has been fully consumed.

Specified by:

onContentReceived in class AbstractAsyncResponseConsumer<HttpResponse>

Parameters:

decoder - content decoder.

ioControl - I/O control of the underlying connection.

Throws:

java.io.IOException - in case of an I/O error

releaseResources

protected void releaseResources()

Description copied from class: AbstractAsyncResponseConsumer

Invoked to release all system resources currently allocated.

Specified by:

releaseResources in class AbstractAsyncResponseConsumer<HttpResponse>

buildResult

protected HttpResponse buildResult(HttpContext context)

Description copied from class: AbstractAsyncResponseConsumer

Invoked to generate a result object from the received HTTP response message.

Specified by:

buildResult in class AbstractAsyncResponseConsumer<HttpResponse>

Parameters:

context - HTTP context.

Returns:

result of the response processing.
