org.apache.http.nio.protocol.BasicAsyncResponseProducer

All Implemented Interfaces:

Closeable, AutoCloseable, HttpAsyncResponseProducer

public class BasicAsyncResponseProducer
extends Object
implements HttpAsyncResponseProducer

Basic implementation of HttpAsyncResponseProducer. The producer can make use of the HttpAsyncContentProducer interface to efficiently stream out message content to the underlying non-blocking HTTP connection, if it is implemented by the HttpEntity inclosed in the response.

Constructor Details

BasicAsyncResponseProducer

public BasicAsyncResponseProducer(HttpResponse response)

Creates a producer that can be used to transmit the given response message. If the response message encloses an HttpEntity it is also expected to implement HttpAsyncContentProducer.

Parameters:

response - response message.

Method Details

generateResponse

public HttpResponse generateResponse()

Description copied from interface: HttpAsyncResponseProducer

Invoked to generate a HTTP response message head.

Specified by:

generateResponse in interface HttpAsyncResponseProducer

Returns:

HTTP response message.

produceContent

public void produceContent(ContentEncoder encoder,
 IOControl ioctrl)
                    throws IOException

Description copied from interface: HttpAsyncResponseProducer

Invoked to write out a chunk of content to the ContentEncoder. The IOControl interface can be used to suspend output event notifications if the producer is temporarily unable to produce more content.

When all content is finished, the producer MUST call ContentEncoder.complete(). Failure to do so may cause the entity to be incorrectly delimited.

Please note that the ContentEncoder object is not thread-safe and should only be used within the context of this method call. The IOControl object can be shared and used on other thread to resume output event notifications when more content is made available.

Specified by:

produceContent in interface HttpAsyncResponseProducer

Parameters:

encoder - content encoder.

ioctrl - I/O control of the underlying connection.

Throws:

IOException - in case of an I/O error

responseCompleted

public void responseCompleted(HttpContext context)

Description copied from interface: HttpAsyncResponseProducer

Invoked to signal that the response has been fully written out.

Specified by:

responseCompleted in interface HttpAsyncResponseProducer

Parameters:

context - HTTP context

failed

public void failed(Exception ex)

Description copied from interface: HttpAsyncResponseProducer

Invoked to signal that the response processing terminated abnormally.

Specified by:

failed in interface HttpAsyncResponseProducer

Parameters:

ex - exception

close

public void close()
           throws IOException

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Throws:

IOException

toString

public String toString()

Overrides:

toString in class Object
