Question

I have a class X which has say do method.

I have another two classes A & B in which object of X is created.

Is there any way by which I can find out whether x’s do() is getting called by A or B.

I do not want to use parameter in do() method. Anything from call trace or something?

I am using struts2, Spring. So any help from frameworks???

I want to implement some logic in do() based on whether its called from A or B.

Answer 1

I understand this looks wired but existing logic will can be quickly tweeted to work for this.

The scenario is,

I have two actions A & B which calls the service X.

X is intercepted by Spring AOP to add filters and passed to DAO’s.

If A calls X then show all data i.e do not apply filter, if B calls X then show data only of logged in user.

X is already intercepted for adding some other filters, so it will be easy to add one more filter. Also this filter is present centrally so all A’s or B’s call X and thus X will do the work accordingly.

I found much better way here, have a instance variable inside X and A’s instance of X will have value ‘a’ and so on.

So now I will be able to distinguish between A’s call of X and B’s call of X.

Does it make sense?
