I solved the problem by moving the class Obj definition out of
the class MyInfo.
I still don't understand why I had to do that. In C++ this would
work without problem.
I now have
interface Info {. . .}
class Obj : Info {. . .}
class MyInfos
{
. . .
static immutable Obj one = new immutable Obj(...);
static immutable Obj two = new immutable Obj(...);
. . .
}
This now compiles without a peep.
But I now met another error in my main(). I can't assign the
immutable object to a mutable reference.
Info x1 = MyInfos.one;
Is it possible to define a mutable reference to an immutable
instance ?
This is confusing and frustrating. In C++ we can write
MyInfos {
. . .
// one is a constant pointer to a constant object of type Obj
Obj const * const one;
. . .
}
And in main()
Info const * x1 = MyInfos.one;
x1 i a modifiable pointer to a constant object of type Info.
Is this possible in D ? I couldn't find how to do that.
