--------------------------------------------------------------
i want to invoke a method with the help of object instance of the same class from within a
method which i m generating dynamically with the help of javassist, i m finding it
difficult to implement. A similar method is present with javassist called
http://www.csg.ci.i.u-tokyo.ac.jp/~chiba/javassist/html/javassist/CtNewMe...
delegator
for reference : with the help of delegator we can call the same method with super
int f(int p, int q) {
return super.f(p, q);
}
i wish to generate the method f dynamically and call the base class method f with the help
of the object instance of base class which is injected to the dynamically generated
class.
int f(int p, int q) {
return objectInstance.f(p, q);
}
i m getting this objectInstance before generating this class and use it to set the field
which is also being added dynamically to this class.
*assume the scenario below for better understanding:*
public class A(){
public A(Object B,Object C){//A's constructor}
public int f(int p, int q){
return p+q;
}
}
main(){
C c=new C();
B b=new B();
A a=new A(b,c);
dynamic(a);
}
i want to code dynamic(Object objectInstance) i a way such that the dynamically added
class looks like...
public class newA(){
private Object objectInstance;
public void setter(Object obj){
this.objectInstance=obj;
}
public Object getter(){
return this.objectInstance;
}
public int f(int p, int q) {
return objectInstance.f(p, q);
}
}
