I have tried this sample:
import std.stdio;
class Notifier
{
int i;
this( int i_value )
{
i = i_value;
}
}
class Message
{
public Notifier notifier;
this( Notifier notifier_object )
{
notifier = notifier_object;
}
}
void
main()
{
void show( Message m )
{
writefln( &m.notifier, ": ", m.notifier.i );
}
auto m1 = new Message( new Notifier( 1 ) );
show( m1 );
auto m2 = new invariant(Message)( new Notifier( 2 ) );
show( m2 );
m2.notifier = new Notifier( 3 );
show( m2 );
}
and got:
882FF8: 1
882FD8: 2
882FD8: 3
Why m2 is not an invariant object?
