Re: [aspectj-users] Introducing constructor with parameters

[Matthew Webster <matthew_webster@xxxxxxxxxx>]

Andre,

Unfortunately the trick of using an ITD on an interface and implementing
that interface (perhaps with a declare parents statement ) that can be used
with methods cannot be used for constructors. Are you suggesting that the
ITD should fail silently? Are you trying to create a robust aspect that
will survive changes in the base code? This is usually the motivation when
writing pointcuts for dynamic cross-cutting. However with static
cross-cutting you cannot use type patterns or wildcards so the declarations
are more specific and hence closely coupled to the target type although
still ensuring good modularity. Being told the ITD has failed is probably
desirable as it may indicate the modularity has been broken.

Subject:    [aspectj-users] Introducing constructor with parameters


Hi,

I'm trying to write an aspect to introduce a constructor in a particular
class. The problem is that if the class already has the constructor the
compilation fails. Is there a way to fix it?

public mypackage.MyClass.new(String name) {
  super(name);
  System.out.print(" Aditional constructor. ");
}

Thanks,

André
