Sorry, but I think the best thing is that I tell you my current problem: I
don't remember C++ (I just programmed only once a couple of years ago) but
in several object oriented languages, there is the concept of error handling
using exceptions. And of course, this is the case of Smalltalk. I hope you
know what exceptions are so that you can understand what I need.
The thing is that from my code (SqueakDBX) or even from the user of
SqueakDBX I would like to do a certain action depending on the error I got.
But right now, I have no way to identify uniquely an error. The only thing I
can do is to obtain a -1 and then the description. But I don't want to
depend on that to identify a particular error type. Because if tomorrow the
description change....So, what I would love is to uniquely identify an error
in ALL of the OpenDBX library. Something like this:
Error code | Error number | Description
NO_MEMORY | 0 | There is no memory left
LIBRARY_OPEN | 1 | OpenDBX could load the library backend
..... | .... | ....
So, it doesn't matter which handle I have, I know every time I get a
NO_MEMORY it means that ...
So, with this, I can have decisions in my code and decide what to do in
different error situations.
Do you understand this problem? do you think OpenDBX can do something like
this in a future release? does this make sense for you ?
Cheers,
Mariano
