Hello Viraj,
the first case (@XYZ) is how I thought about it (see also the test
code in the attachment). This way .equals() could be implemented
automatically.
Of course you have to override the equals() method like this, if you
would like it to behave "as designed":
// maybe some sort of postprocessing for class files could make this unnecessary
@Override
public boolean equals(Object b) {
return Automatic.equals(this, b);
}
the second case also looks interesting and may be useful.
Regards
--Tim
