I'm overriding the method because I want to change the *implementation*.
The *interface* of it, which is documented in the docblock, should not
change and it's a bug (and possibly compile error) if it does change. You
cannot, for instance, change what parameters the method takes in a subclass.
If you change the meaning of those parameters then you're setting yourself
up for crazy and hard to debug bugs. So the @param documentation absolutely
should be the same for both.
Sure, but @param, @access and possibly @return are but a part. I stand
by my words: document the parent as a stub and provide actual
documentation for the real implementations. Otherwise you're trying to
be *clever* and will see the age-old result: you'll end up shooting
yourself in the foot or worse places.
... What's "clever" about using OO inheritance the way it's designed to
be used? Are you actually suggesting that the solution is to insist on
duplicating the docblock in every child class, which is a huge
I could go through a dozen other examples where this problem exists
where there's nothing "clever" (when that became an epithet I don't
know) going on, just rudimentary OO, but I won't clog the list with it.
What I'm doing in the previous examples is in no way esoteric. This
is OO 101 code.
