public void produceContent(ContentEncoder encoder, IOControl ioctrl) throws java.io.IOException
ProducingNHttpEntity
IOControl
instance passed as a parameter to the method can be
used to suspend output events if the entity is temporarily unable to
produce more content.
When all content is finished, this MUST call ContentEncoder.complete()
.
Failure to do so could result in the entity never being written.

Repeatable
entities are expected
to create a new instance of InputStream
for each invocation
of this method and therefore can be consumed multiple times.
Entities that are not repeatable
are expected
to return the same InputStream
instance and therefore
may not be consumed more than once.
IMPORTANT: Please note all entity implementations must ensure that
all allocated resources are properly deallocated after
the InputStream.close()
method is invoked.

IMPORTANT: Please note all entity implementations must ensure that all allocated resources are properly deallocated when this method returns.

outstream
- the output stream to write entity content to
