 Posted: Sun Apr 18, 2004 7:57 pm Post subject: Abstract Attributes |
 |
|
Java uses the abstract attribute to modify a class name to make abstract classes. D apparently doesn't do it this way. I tried to look up the abstract attribute use in the D reference manual, but it doesn't describe it  .
I know Kris uses abstract in dsc.AbstractServer to create an abstract class. It appears that an abstract class in created in D when the individual class methods are attributed with "abstract." Is there any documentation on this to explain it's use better?
Thanks,
John |

Anybody good at biology? If we cloned Walter, the pair of them might be able to keep up with all of this stuff better. About 1.5 years later, they still aren't described in the docs.  |

in D, an abstract class is implied if any of the methods are abstract.
Decorating the class itself with the abstract keyword (currently) has zero effect. It's probably best to avoid depending on that, and remove the abstract keyword from any Java class.

Thanks Kris, That's what I figured was the case from your examples. I vaguely remembered something about the abstract keyword having zero effect when decorating the class itself.
How did you come across this information? Trial and error? |

| I think Walter noted something like that in a reply to my ranting about Partial Interface Implementation ... |
