Re: [aspectj-users] exclude some originating objects?
|
"Lexically within B" means it is in the body of the
source for class B, if the Java bytecode format permits
that to be determined. It does not include anonymous
inner classes (bytecode does not permit it) or subtypes
outside the body. It does include static contexts
where "this(B)" would not be true (like constructors,
initializers, and static methods).
To pick out subtypes as well, use "within(B+)". Note
by contrast that "this(B)" would be true in an
instance context of any subtype of B.
Also, in a call PCD, when using the declaring type of
the called target type, e.g., "A" in
call(* A.*(..))
"A" refers to the reference type of the call (at compile
time), not the actual (runtime) type of the object
handling the call.
For a discussion of the PCD's within(), this(), etc.,
see the programmers guide.
