Method Detail

traceExchange

void traceExchange(ProcessorDefinition<?> node,
                   Processor target,
                   TraceInterceptor traceInterceptor,
                   Exchange exchange)
            throws Exception

Deprecated.

Event called when an Exchange is about to be processed

This event is only called if trace out has been disabled (which it is by default).

This method is for coarse grained tracing, where as the other two methods is for fine grained with in and event events.

Parameters:

node - the current node

target - the current processor being invoked

traceInterceptor - the trace interceptor

exchange - the current exchange

Throws:

Exception - is thrown if an error occurred during tracing

traceExchangeIn

Object traceExchangeIn(ProcessorDefinition<?> node,
                       Processor target,
                       TraceInterceptor traceInterceptor,
                       Exchange exchange)
                throws Exception

Deprecated.

Event called when an Exchange is about to be processed (in)

This event is only called if trace out has been enabled.

Parameters:

node - the current node

target - the current processor being invoked

traceInterceptor - the trace interceptor

exchange - the current exchange

Returns:

an optional return object to pass in the traceEventOut method.

Throws:

Exception - is thrown if an error occurred during tracing

traceExchangeOut

void traceExchangeOut(ProcessorDefinition<?> node,
                      Processor target,
                      TraceInterceptor traceInterceptor,
                      Exchange exchange,
                      Object traceState)
               throws Exception

Deprecated.

Event called when an Exchange has been processed (out)

This event is only called if trace out has been enabled.

Parameters:

node - the current node

target - the current processor being invoked

traceInterceptor - the trace interceptor

exchange - the current exchange (contains exception if the processing failed with an exception)

traceState - the optional object which was returned from the traceEventIn method.

Throws:

Exception - is thrown if an error occurred during tracing
