[aspectj-users] Q: interposing on calls to superclass constructors

[Godmar Back <godmar@xxxxxxxxx>]

Hi,

does AspectJ allow me to interpose on calls to superclass constructors?

For example, consider the following anonymous class:

    File f = new File("name") { }

which, in bytecode, contains the following constructor:

Method name:"<init>" Signature: (java.lang.String)void
  0: aload_0
  1: aload_1
  2: invokespecial <Method java.io.File.<init> (java.lang.String)void>
  5: return

I would like to capture the superclass invocation in an 'around'
advice so I can manipulate the second argument (here:
java.lang.String, the 'name' passed to the java.io.File(String))
constructor.)

I tried the following, but this pointcut only captures direct
constructor calls, not those occurring in subclass constructors.

    pointcut FileCreation(String fname):
        call(java.io.File.new (String)) && args(fname);

    java.io.File around(String name) : FileCreation(name) {
        return proceed(toGlobalName(name));
    }

What is the correct pointcut to express this?

Thanks!
