java.lang.Objectorg.apache.http.nio.protocol.BasicAsyncRequestProducer
@ThreadSafe public class BasicAsyncRequestProducer
Basic implementation of HttpAsyncRequestProducer. 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 enclosed HttpEntity.

protected BasicAsyncRequestProducer(HttpHost target,
HttpEntityEnclosingRequest request,
HttpAsyncContentProducer producer)
HttpEntity whose properties are consistent with the behavior
of the content producer.
target - target host.request - request message.producer - request content producer.

HttpRequest request)
HttpEntity
it is also expected to implement HttpAsyncContentProducer.

public HttpRequest generateRequest()
HttpAsyncRequestProducerHttpEntityEnclosingRequest interface if it is
to enclose a content entity. The HttpAsyncRequestProducer.produceContent(ContentEncoder, IOControl)
method will not be invoked if HttpEntityEnclosingRequest.getEntity()
returns null.

public void produceContent(ContentEncoder encoder,
IOControl ioctrl)
throws IOException
HttpAsyncRequestProducerContentEncoder.
The IOControl interface can be used to suspend output events
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.
