Replacing Methods From Different Classes
Hi,
I am trying to replace a method binding from one class with another method in another class. I haven't quite gotten this to work and any help would be appreciated. Consider the example below:
public class A {
public class X {
public X() {
m(); //can this be changed?
}
public void m() {
System.out.println("A.X.m()");
}
}
public static void main (String args []) {
A a = new A();
X x = a.new X();
}
}
public class B extends A {
public class X {
public void m() {
System.out.println("B.X.m()");
}
}
}
I am wondering if it is possible to change A.X.m() to reference B.X.m(). I know the use of inner classes here is not essential, and the fact that B extends A would make the need for overriding A.X.m() in A seemingly absurd. This is more of a test to see if methods can be replaced in odd contexts. My real goal is much larger.
I have used BCELifier to create some files and I tried to edit them to reflect the desired change, but got stuck on VerifiyErrors. I'm not sure exactly what needs to be updated. Also, I thought ClassGen.replaceMethod would work, but found a few errors. Can anyone provide some insights?
