Constructor Detail

ChoiceProcessor

public ChoiceProcessor(List<FilterProcessor> filters,
                       Processor otherwise)
Method Detail

process

public void process(Exchange exchange)
             throws Exception
Description copied from interface: Processor
Processes the message exchange

Specified by:
process in interface Processor
Parameters:
exchange - the message exchange
Throws:
Exception - if an internal processing error has occurred.

process

public boolean process(Exchange exchange,
                       AsyncCallback callback)
Description copied from interface: AsyncProcessor
Processes the message exchange. Similar to Processor.process(org.apache.camel.Exchange), but the caller supports having the exchange asynchronously processed.

If there was a failure processing then the caused Exception would be set on the Exchange.

Specified by:
process in interface AsyncProcessor
Parameters:
exchange - the message exchange
callback - the AsyncCallback will be invoked when the processing of the exchange is completed. If the exchange is completed synchronously, then the callback is also invoked synchronously. The callback should therefore be careful of starting recursive loop.
Returns:
(doneSync) true to continue execute synchronously, false to continue being executed asynchronously
See Also:
AsyncProcessorHelper.process(AsyncProcessor, Exchange, AsyncCallback)

toString

public String toString()
Overrides:
toString in class Object

getTraceLabel

public String getTraceLabel()
Description copied from interface: Traceable
Gets the trace label used for logging when tracing is enabled.

The label should be short and precise.

Specified by:
getTraceLabel in interface Traceable
Returns:
the label

getFilters

public List<FilterProcessor> getFilters()

getOtherwise

public Processor getOtherwise()

next

public List<Processor> next()
Description copied from interface: Navigate
Next group of outputs

Specified by:
next in interface Navigate<Processor>
Returns:
next group or null if no more outputs

hasNext

public boolean hasNext()
Description copied from interface: Navigate
Are there more outputs?

Specified by:
hasNext in interface Navigate<Processor>
Returns:
true if more outputs

doStart

protected void doStart()
                throws Exception
Specified by:
doStart in class ServiceSupport
Throws:
Exception

doStop

protected void doStop()
               throws Exception
Specified by:
doStop in class ServiceSupport
Throws:
Exception
