Re: [aspectj-users] Need help with point cuts for subclasses

[Matthew Webster <matthew_webster@xxxxxxxxxx>]

Manjula,

I think you need this (note the "+"
symbol) which means "ISTSFXmlTxn
and all subclasses":

pointcut excluded() :
within(com.apple.ist.istsf.aspects..*);

pointcut sendBamLog(ISTSFXmlTxn txn) : target(txn)  &&
execution(* com.apple.ist.istsf.util.ISTSFXmlTxn+.process(..)) &&
!excluded();

Subject:        [aspectj-users] Need help with point cuts for subclasses


Hi All,

We've a simple aspect for publishing data to BAM and
it was all working fine. Originally, the point cut was
as below:

pointcut excluded() :
within(com.ist.espresso.aspects..*);

pointcut sendBamLog(EspressoXmlTxn txn) : target(txn)
&& execution(*
com.ist.ruby.services.espresso.EspressoXmlTxn.process(..))
&& !excluded();


As part of making this code generic, we introduce a
class called ISTSFXml. This ISTSFXml class is an
abstract class which has an abstract method
process.We've re-written the aspect as below.

pointcut excluded() :
within(com.apple.ist.istsf.aspects..*);

pointcut sendBamLog(ISTSFXmlTxn txn) : target(txn)  &&
execution(*
com.apple.ist.istsf.util.ISTSFXmlTxn.process(..)) &&
!excluded();


The idea is that any class that extends ISTSFXmlTxn
will implement the process method and the point cut
should be invoked for those subclasses. But i don't
see the pointcut getting called.


Could someone please let me know what's the mistake
i'm doing here?

Thanks for anyinput in advance,
Manjula
