Question

[Jay Kamdar]

Let say you are in one class and you want to find out when another method is called and you want to call one of your methods right after.

Is that possible, can you use a thread to do that?

hi,

as 100% of the forum posts are questions, it would be a good idea to look for a more self explaining name for your post. "question" is a bit too vague... :-)

to answer your question: yes, it's possible. but not with a finger snip. the approach would be aop (aspect oriented programming, which was actually developed for such requirements. but that's too big to explain in one sentence (at least for me). have a look at the spring-framework, they give an excellent introduction, and see if this is of some use for you. aspectJ would be another alternative, but i consider spring to be easier to use.

oh, and yes - if all this is way too much, have a look at the proxy pattern in general and dynamic proxies in special.

hope it helps you to get started,
jan

If you are allowed to design the class with the closely watched method, I think the observer pattern might be useful, if you don't want to go for the full monty of AOP/dynamic proxies:
