Method Detail

onRequestReceived

protected void onRequestReceived(HttpRequest request)
                          throws java.io.IOException

Description copied from class: AbstractAsyncRequestConsumer

Invoked when a HTTP request message is received. Please note that the AbstractAsyncRequestConsumer.onContentReceived(ContentDecoder, IOControl) method will be invoked only for if the request message implements HttpEntityEnclosingRequest interface and has a content entity enclosed.

Specified by:

onRequestReceived in class AbstractAsyncRequestConsumer<HttpRequest>

Parameters:

request - HTTP request 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: AbstractAsyncRequestConsumer

Invoked if the request message encloses a content entity.

Specified by:

onEntityEnclosed in class AbstractAsyncRequestConsumer<HttpRequest>

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 ioctrl)
                          throws java.io.IOException

Description copied from class: AbstractAsyncRequestConsumer

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 AbstractAsyncRequestConsumer<HttpRequest>

Parameters:

decoder - content decoder.

ioctrl - 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: AbstractAsyncRequestConsumer

Invoked to release all system resources currently allocated.

Specified by:

releaseResources in class AbstractAsyncRequestConsumer<HttpRequest>

buildResult

protected HttpRequest buildResult(HttpContext context)

Description copied from class: AbstractAsyncRequestConsumer

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

Specified by:

buildResult in class AbstractAsyncRequestConsumer<HttpRequest>

Parameters:

context - HTTP context.

Returns:

result of the request processing.
