Annotation which invokes a method

Question

I'll start with a piece of code

class Clazz {

    public void doSomething() {
        ...
        check();
    }

    public void doSomethingElse() {
        ...
        check();
    }

    ... // etc., these methods look basically the same - they all call check() at the end
}

Is it possible to annotate methods like @Checked which would cause to call the check() at the end? And if it is, can you provide some examples?

Answer 1

Yeah - it is possible. You need to instrument your code, typically with aspects (AOP). Check out this example if you want to see what it looks like.
