- All Implemented Interfaces:

FilterProcessor
public FilterProcessor(Predicate predicate,
Processor processor)
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
- Overrides:
process
in class DelegateAsyncProcessor
- Parameters:
exchange
- the message exchangecallback
- 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
toString
public String toString()
- Overrides:
toString
in class DelegateAsyncProcessor
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
getPredicate
public Predicate getPredicate()
doStart
protected void doStart()
throws Exception
- Description copied from class:
ServiceSupport
- Implementations override this method to support customized start/stop.
Important: See
ServiceSupport.doStop()
for more details.
- Overrides:
doStart
in class DelegateAsyncProcessor
- Throws:
Exception
- See Also:
ServiceSupport.doStop()
doStop
protected void doStop()
throws Exception
- Description copied from class:
ServiceSupport
- Implementations override this method to support customized start/stop.
Important: Camel will invoke this
ServiceSupport.doStop()
method when
the service is being stopped. This method will also be invoked
if the service is still in uninitialized state (eg has not
been started). The method is always called to allow the service
to do custom logic when the service is being stopped, such as when
CamelContext
is shutting down.
- Overrides:
doStop
in class DelegateAsyncProcessor
- Throws:
Exception
- See Also:
ServiceSupport.doStart()
