set$AroundClosure
void set$AroundClosure(org.aspectj.runtime.internal.AroundClosure arc)
The joinpoint needs to know about its closure so that proceed can delegate to closure.run() This internal method should not be called directly, and won't be visible to the end-user when packed in a jar (synthetic method)- Parameters:
arc

proceed
java.lang.Object proceed() throws java.lang.Throwable
Proceed with the next advice or target method invocation- Returns:
- Throws:
java.lang.Throwable
-
proceed
java.lang.Object proceed(java.lang.Object[] args) throws java.lang.Throwable
Proceed with the next advice or target method invocationUnlike code style, proceed(..) in annotation style places different requirements on the parameters passed to it. The proceed(..) call takes, in this order:
- If 'this()' was used in the pointcut for binding, it must be passed first in proceed(..).
- If 'target()' was used in the pointcut for binding, it must be passed next in proceed(..) - it will be the first argument to proceed(..) if this() was not used for binding.
- Finally come all the arguments expected at the join point, in the order they are supplied at the join point. Effectively the advice signature is ignored - it doesn't matter if a subset of arguments were bound or the ordering was changed in the advice signature, the proceed(..) calls takes all of them in the right order for the join point.
Since proceed(..) in this case takes an Object array, AspectJ cannot do as much compile time checking as it can for code style. If the rules above aren't obeyed then it will unfortunately manifest as a runtime error.
