Method Details

execute

public void execute(ChenileExchange exchange)
             throws Exception

Description copied from class: BaseChenileInterceptor

If this method is over-ridden, make sure that you call doContinue unless you want to end the chain here! This is very important. Also, if there is an exception downstream it needs to be handled here after a call to BaseChenileInterceptor.doContinue(ChenileExchange) In most cases, you will do fine overriding BaseChenileInterceptor.doPreProcessing(ChenileExchange) and BaseChenileInterceptor.doPostProcessing(ChenileExchange)
