Re: Abstractclass: store with reference-descriptor in two tables

[Armin Waibel]

Hi,

I think we have a documentation bug, try to set all auto-XXX attributes 
in super-references to true and see what's going on.
By default auto-update is false (docu says it's true).

regards,

public class B extends A
{
    int my_id;                      // id is the primary key
    int ref_ID;                     // aID is the foreign key referencing
A.id
    int someValueFromB;       // mapped to a column in B_TABLE
    public int getSomeValueFromB() {        return someValueFromB;    }
    public void setSomeValueFromB(int someValueFromB) {
this.someValueFromB = someValueFromB;    }
    public int getMy_id() {        return my_id;    }
    public void setMy_id(int my_id) {        this.my_id = my_id;    }
    public int getRef_ID() {        return ref_ID;    }
    public void setRef_ID(int ref_ID) {        this.ref_ID = ref_ID;    }
}
Class B:
===========================================
package de.intermediate.epic;

public class A
{
    int ida;                        // primary key
    int someValueFromA;       // mapped to a column in A_TABLE
    public int getSomeValueFromA() {        return someValueFromA;    }
    public void setSomeValueFromA(int someValueFromA) { this.someValueFromA
= someValueFromA; }
    public int getIda() { return ida; }
    public void setIda(int ida) { this.ida = ida;}
}
