Class ExceptionTranslationAdvice

java.lang.Object
  org.springframework.flex.core.ExceptionTranslationAdvice

All Implemented Interfaces:

org.aopalliance.aop.Advice, AfterAdvice, ThrowsAdvice

public class ExceptionTranslationAdvice
extends Object
implements ThrowsAdvice

Catches Throwable objects and looks for a registered ExceptionTranslator that knows how to translate them to more specific BlazeDS MessageExceptions to be re-thrown so that a proper AMF error will be sent back to the client.

If the caught object is an instance of MessageException with the generic "Server.Processing" fault code, a translator will be looked up for the root cause exception type rather than the generic wrapper MessageException.
