RE: [aspectj-users] passing an extra parameter to existing method s
|
Title: Message
Mark,
I was
also looking into something where pattern-based method introduction would be
usefull. I was trying to code an aspect that would enhance the methods of
Collection to make every Collection synchronized. Could be usefull if you
suddently find your components running in multiple threads and you don't want to
change all your Collections to Vector or Hashtable because the same components
are being used in another application that is not
multi-threaded.
Rudi.
I think what I want is a pattern-based form of method introduction ...
unless there is another approach that would provide this same
thing.
Is there a way I could do the following with AspectJ?
I want to add methods to several classes that wrap existing
methods and add an additional parameter.
Then I want
to use around advice to make calls to the original methods go to the new
methods and add the new parameter.
For example, the deposit method in my Account class looks
like this.
public void deposit(double amount) {
balance += amount;
}
I want to add the following.
public void deposit(Context context, double amount) {
deposit(amount);
// Do something with the context parameter
here.
}
Then all calls to the original deposit method should go to
the new one.
I know how to do this for individual methods, but I'm
looking for a way to do this to many methods in the Account class without
having to write the code for each of them in my
aspect.
