Method Detail

getFuture

public Future<T> getFuture()

Deprecated.

close

public void close()
           throws IOException

Deprecated.

Specified by:

close in interface Closeable

Throws:

IOException

getTarget

public HttpHost getTarget()

Deprecated.

Description copied from interface: HttpAsyncRequestProducer

Invoked to obtain the request target host.

Specified by:

getTarget in interface HttpAsyncRequestProducer

generateRequest

public HttpRequest generateRequest()
                            throws IOException,
                                   HttpException

Deprecated.

Description copied from interface: HttpAsyncRequestProducer

Invoked to generate a HTTP request message head. The message is expected to implement the HttpEntityEnclosingRequest interface if it is to enclose a content entity. The HttpAsyncRequestProducer.produceContent( ContentEncoder, IOControl) method will not be invoked if HttpEntityEnclosingRequest.getEntity() returns null.

Specified by:

generateRequest in interface HttpAsyncRequestProducer

Returns:

HTTP request message.

Throws:

IOException - in case of an I/O error

HttpException - in case of HTTP protocol violation

produceContent

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

Deprecated.

Description copied from interface: HttpAsyncRequestProducer

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 HttpAsyncRequestProducer

Parameters:

encoder - content encoder.

ioControl - I/O control of the underlying connection.

Throws:

IOException - in case of an I/O error

requestCompleted

public void requestCompleted(HttpContext context)

Deprecated.

Description copied from interface: HttpAsyncRequestProducer

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

Specified by:

requestCompleted in interface HttpAsyncRequestProducer

Parameters:

context - HTTP context

isRepeatable

public boolean isRepeatable()

Deprecated.

Description copied from interface: HttpAsyncRequestProducer

Determines whether or not this producer is capable of producing HTTP request messages more than once.

Specified by:

isRepeatable in interface HttpAsyncRequestProducer

resetRequest

public void resetRequest()

Deprecated.

Description copied from interface: HttpAsyncRequestProducer

Invoked to reset the producer to its initial state. Repeatable request producers are expected to release currently allocated resources that are no longer needed or re-acquire resources needed to repeat the process.

Specified by:

resetRequest in interface HttpAsyncRequestProducer

responseReceived

public void responseReceived(HttpResponse response)
                      throws IOException,
                             HttpException

Deprecated.

Description copied from interface: HttpAsyncResponseConsumer

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

Specified by:

responseReceived in interface HttpAsyncResponseConsumer<T>

Parameters:

response - HTTP response message.

Throws:

IOException - in case of an I/O error

HttpException - in case of HTTP protocol violation

consumeContent

public void consumeContent(ContentDecoder decoder,
                           IOControl ioControl)
                    throws IOException

Deprecated.

Description copied from interface: HttpAsyncResponseConsumer

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

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

Please note that the ContentDecoder 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 input event notifications when the consumer is capable of processing more content.

Specified by:

consumeContent in interface HttpAsyncResponseConsumer<T>

Parameters:

decoder - content decoder.

ioControl - I/O control of the underlying connection.

Throws:

IOException - in case of an I/O error

failed

Deprecated.

Description copied from interface: HttpAsyncRequestProducer

Invoked to signal that the response processing terminated abnormally.

Specified by:

failed in interface HttpAsyncRequestProducer

Specified by:

failed in interface HttpAsyncResponseConsumer<T>

Parameters:

ex - exception

cancel

public boolean cancel()

Deprecated.

Specified by:

cancel in interface Cancellable

responseCompleted

public void responseCompleted(HttpContext context)

Deprecated.

Description copied from interface: HttpAsyncResponseConsumer

Invoked to signal that the response has been fully processed.

Specified by:

responseCompleted in interface HttpAsyncResponseConsumer<T>

Parameters:

context - HTTP context

getResult

public T getResult()

See Also:

HttpAsyncResponseConsumer.isDone()
