| [aspectj-users] Newbie question on inter-type member declarations |
|
Hello!
I'm wondering if it's possible in AspectJ to add
inter-type member declarations based on pointcuts? A little example to
illustrate what I mean:
We have a web application using Struts. For
convenience we have introduced a naming convention requiring
certain properties in our domain model classes to have extra ...AsString
properties that formats the properties correctly for presentation in web pages
(using Struts taglibs). So if we have a property 'salary' in the Employee
class we will also have a property 'salaryAsString' that returns the salary
(originally a double) as a string with thousand separators and two decimal
precision.
Is it possible to enforce this convention
throughout the application with an aspect? Of course, We could list
each ...AsString method as an inter-type member declaration in the
aspect, but that won't be much of an improvement wrt programming effort. It
would be much better if we could make a pointcut selecting all get and
set methods of interest and then apply an advice on them that added the extra
methods...
Regards,
Are Meisfjord
