Re: [aspectj-dev] how much is dynamic?
|
Luca,
You should now read the help pages that come with the 1.1.X release of
AspectJ. They have more details and updated information.
You can compile from source, using "ajc" like javac. In 1.1, you can now
use ajc to weave-in aspects into existing byte code. So, you don't have
to recompile your sources. You can even create jar files of pre-compiled
aspects and weave them later.
In a sense, the 1.1 byte-code support is like old-style linking. This
step is necessary so ajc can manipulate the advised classes as needed
before they are loaded by the JVM.
Hope this helps a bit.

Hello to everyone,
I'm new to the AspectJ world, hence my questions could be trivial. If so
please apologize myself, I'm just trying to understand.
I've read the paper "An overview of AspectJ" and I cannot understand if the
aspect weaver is dynamic or not. IN the paper the author talks about an
aspect compiler, but is it a compiler at the same level of the javac
compiler? I mean : is it possible to take a (ordinary) compiled class and
load it (into a running JVM) "attaching" aspetcs to it, or I need to
recompile the class starting from the source? I know that the main advantage
of aspects is to fuse crosscuts without requiring source code alerations, but
my question is related to the use of apsect starting from an alredy compiled
class.
Thanks,
Luca
