public Processor wrapProcessorInInterceptors(CamelContext context,
                                             ProcessorDefinition<?> definition,

Description copied from interface: InterceptStrategy

This method is invoked by ProcessorDefinition.wrapProcessor(RouteContext, Processor) to give the implementor an opportunity to wrap the target processor in a route.

Important: See the class javadoc for advice on letting interceptor be compatible with the asynchronous routing engine.

Specified by:

wrapProcessorInInterceptors in interface InterceptStrategy

Parameters:

context - Camel context

definition - the model this interceptor represents

target - the processor to be wrapped

nextTarget - the next processor to be routed to

Returns:

processor wrapped with an interceptor or not wrapped.

Throws:

Exception - can be thrown

shouldTrace

public boolean shouldTrace(ProcessorDefinition<?> definition)

Whether or not to trace the given processor definition.

Parameters:

definition - the processor definition

Returns:

true to trace, false to skip tracing
