It depends. You can certainly implement it like that (that's basically what things like AspectJ do).

You can also do it dynamically at runtime (e.g. with Hook::Lexwrap in Perl - which is basically what Aspect does.)

What a full AOP system gives you is the ability to do it in a structured way - making maintenance less of a nightmare.
