javaaspectjpointcut

I am searching for a specific pointcut in AspectJ

The line:

test.address.postal_code = "12345";

will result in a flow like:

before-get test.address
    return test.address
after-get test.address
before-set test.address.postal_code
    set postal_code
after-set test.address.postal_code

in AspectJ. Is there a pointcut that will have test as target (like before-get test.adddres and after-get test.address) but will occur after "after-set test.address.postal_code" ?

Solution

  • No, because your line of code is equivalent to:

    Object address = test.address;
address.postal_code = "12345";

    I.e. the two field accesses (first read, then write) are done one after another. Chaining them as you did in a "fluent" way is just syntactic sugar. BTW, if your Test class can directly access Address members, you have an encapsulation problem anyway, but this is just a personal remark.

    If you want to know if the address is assigned to a member of another class you need to keep state within the aspect, which is possible but a bit dirty. Maybe you want to change the application design instead of patching up bad design with hacky aspects. ;-)
