Examples of InterceptStrategy

org.apache.camel.spi.InterceptStrategy
The purpose of this interface is to allow an implementation to wrap processors in a route with interceptors. For example, a possible usecase is to gather performance statistics at the processor's level. @version $Revision: 679971 $

Examples of org.apache.camel.spi.InterceptStrategy

        // create the output processor
        // TODO: This should be mandatory (but ExceptionHandlerStreamCacheTest fails)
        output = this.createChildProcessor(routeContext, false);


        // add the output as a intercept strategy to the route context so its invoked on each processing step
        routeContext.getInterceptStrategies().add(new InterceptStrategy() {
            private Processor interceptedTarget;


            public Processor wrapProcessorInInterceptors(CamelContext context, ProcessorDefinition definition,
                                                         Processor target, Processor nextTarget) throws Exception {
                // prefer next target over target as next target is the real target
