Java extends classes - Share the extended class fields within the super class.
- by Bastan
Straight to the point... I have a class
public class P_Gen{
protected String s;
protected Object oP_Gen;
public P_Gen(String str){
s = str;
oP_Gen = new Myclass(this);
}
}
Extended class:
public class P extends P_Gen{
protected Object oP;
public P(String str){
oP = new aClass(str);
super(str);
}
}
MyClass:
public class MyClass{
protected Object oMC;
public MyClass(P extendedObject){
oMc = oP.getSomething();
}
}
I came to realize that MyClass can only be instantiated with (P_Gen thisObject) as opposed to (P extendedObject).
The situation is that I have code generated a bunch of classes like P_Gen. For each of them I have generated a class P which would contains my P specific custom methods and fields.
When I'll regenerate my code in the future, P would not be overwritten as P_Gen would.
** So what happened in my case???!!!... I realized that MyClass would beneficiate from the info stored in P in addition to only P_Gen. Would that possible?
I know it's not JAVA "realistic" since another class that extends P_Gen might not have the same fields...
BY DESIGN, P_Gen will not be extended by anything but P.... And that's where it kinda make sens. :-) at least in other programming language ;-)
In other programming language, it seems like P_Gen.this === P.this, in other word, "this" becomes a combination of P and P_Gen.
Is there a way to achieve this knowing that P_Gen won't be extended by anything than P?
