public void produceContent(ContentEncoder encoder, IOControl ioctrl) throws java.io.IOException
HttpAsyncContentProducer
ContentEncoder
.
The IOControl
interface can be used to suspend output event
notifications if the entity 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.
