Class SharedCamelInternalProcessor

java.lang.Object
org.apache.camel.impl.engine.SharedCamelInternalProcessor
All Implemented Interfaces:
org.apache.camel.Processor, org.apache.camel.spi.SharedInternalProcessor
public class SharedCamelInternalProcessor extends Object implements org.apache.camel.spi.SharedInternalProcessor
A Shared (thread safe) internal Processor that Camel routing engine used during routing for cross cutting functionality such as:
  • Execute UnitOfWork
  • Keeping track which route currently is being routed
  • Execute RoutePolicy
  • Gather JMX performance statics
  • Tracing
  • Debugging
  • Message History
  • Stream Caching
  • Transformer
... and more.

This implementation executes this cross cutting functionality as a CamelInternalProcessorAdvice advice (before and after advice) by executing the CamelInternalProcessorAdvice.before(Exchange) and CamelInternalProcessorAdvice.after(Exchange, Object) callbacks in correct order during routing. This reduces number of stack frames needed during routing, and reduce the number of lines in stacktraces, as well makes debugging the routing engine easier for end users.

Debugging tips: Camel end users whom want to debug their Camel applications with the Camel source code, then make sure to read the source code of this class about the debugging tips, which you can find in the process(Exchange, AsyncCallback, AsyncProcessor, Processor) method.
