[xmlvm-users] Default values of member variables

[Markus H. <ma...@ti...>]

Hi,

take this code convert it to objc and run it:

public class Test{
    Object thisIsNotInitialized;

    void test(){
         if(thisIsNotInitialized==null)
             System.out.println("null");
    }

    public static void main(String[] args){
        new Test().test();
    }
}

I would expect to get "null" printed to the console. But that doesn't  
happen. The generated if is something like thos:

if (_op1.o != [NSNull null]) goto label0;

So it checks for [NSNull null]. But _op1.o contains 0x0 and the check  
is false. So I would guess that the initialization code of the ObjC  
variables has to be changed so that they contain [NSNull null] and not  
0x0 by default.

Hope you get what I mean.

Markus
