Hi,
I have 4 interfaces:
public interface Ainterface{
getName()/setName();
getShape()/setShape();
....
}
public interface Binterface extends Ainterface{
getWidth()/setWidth();
getHeight()/setHeight();
...
}
public interface Cinterface extends Ainterface{
getRadius()/setRadius();
...
}
public interface Dinterface {
Ainterface getA();
void setA(Ainterface a);
...
}
I have included all interfaces in my AutoBeanFactory.
Question: when I decode/encode Dinterface, how do I know if Ainterface is
extended by Binterface or Cinterface? How does AutoBean support
polymorphism?
To make it easier, I can add a variable (for ex, shape) in Ainterface to
indicate which Binterface or Cinterface I have and then cast Ainterface to
Binterface/Cinterface. However, I run into ClassCastException. Should I
have separate interfaces; one that consists Binterface and one consists
Cinterface? Is there other solution to this problem?
Thank you,
