FileProducer - Some strange code

[Claus Ibsen <ci...@silverbullet.dk>]

Hi

In the file component (FileProducer)

FileProducer (for writing files) has some strange code:

  public void process(FileExchange exchange) throws Exception {
        if (ExchangeHelper.isOutCapable(exchange)) {
            // lets poll the file
            Message out = exchange.getOut(true);
            endpoint.configureMessage(endpoint.getFile(), out);
            return;
        }

        ...
        Normal code to do the writing of the in body


The code above will for all Out capable exchanges (eg InOut) poll a file instead.

I haven't digged deeper yet, but I wanted to hear if anyone knows the reason for this code.

See the unit test in camel-jetty component HttpToFileTest that demonstrates a user request on the forum how to save http requests to files.
I needed to change the exchange pattern to in only to avoid the strange code above to kick in.

As I haven't had my 3rd cup of morning coffee yet I am in a state where I can't read the code to well to understand the holy reason for it ;)

I'm still only midway through my first cup :) I've got a hazy memory
of it being to do with file polling; but then I'd have thought this
would have been in the consumer not the producer side?
