Re: [aspectj-users] obtaining aspect value from advice around field get pointcut

My inability to figure this out may be based on my weak understanding of how the get pointcut works in fhe first place, so I apologize in advance.

I have something like the following in a class:

Class Foo
{
@MyAnnotation("aValue")
private String field;
}

and within an aspect:

String around() : get(@MyAnnotation * *)
{
//HERE
}


Change this to 

String around(MyAnnotation annotation) : get(@MyAnnotation * *.*) && @annotation(annotation) {
// do something with annotation.value();  // Get the string in the annotation.
}

Note that your get(...) had a little bug; the 3 '*' are the type, class, and field. 

Hope this helps.

How do I get the value of "aValue" from within the advice (marked //HERE)? I can get the target class and find fields, etc...but I need to know which field is the "target" (don't think it is considered a target from AspectJ's perspective) of the pointcut, etc.
