Hi,
I want to implement a custom AsyncProcessor so I can have more control on a
custom Netty channel. Is the following pattern recommended?
@Override
public boolean process(Exchange exchange, AsyncCallback callback) {
try {
//Do whatever sync preparations and async invocations,
set the exchange
result and signal back
// continue routing asynchronously
return false;
} catch (Exception e) {
//If an excepction was thrown synchronously, handle it
here, do not throw
it
exchange.setException(e);
callback.done(true);
return true;
}
}
CamelInternalProcessor has this code:
// ----------------------------------------------------------
// CAMEL END USER - DEBUG ME HERE +++ START +++
// ----------------------------------------------------------
try {
processor.process(exchange);
} catch (Throwable e) {
exchange.setException(e);
}
// ----------------------------------------------------------
// CAMEL END USER - DEBUG ME HERE +++ END +++
// ----------------------------------------------------------
// ----------------------------------------------------------
// CAMEL END USER - DEBUG ME HERE +++ START +++
// ----------------------------------------------------------
if (LOG.isTraceEnabled()) {
LOG.trace("Processing exchange for exchangeId: {} -> {}",
exchange.getExchangeId(), exchange);
}
boolean sync = processor.process(exchange, async);
// ----------------------------------------------------------
// CAMEL END USER - DEBUG ME HERE +++ END +++
// ----------------------------------------------------------
In the synchronous version, it uses a try catch. Why does this
implementation not use a try-catch in the asynchronous version?
Thanks!
By the way, I've been posting a lot these days, thanks for your help! I
really appreciate it. I'm having a hard time to use Eclipse on Camel source
code projects. As soon as I could get over it, I would like to contribute.
Thanks!
