Excellent. Now I got it.
Suppose I want to map from OpenDBX errors to SqueakDBX exceptions, I have to
do it with the index of the array then. So, if you then change, reorder or
whatever you do with the array, I will map wrong exceptions :(
It would be grate to define static numbers. I mean, numbers that do not
change.
That's the reason why you want to change that in OpenDBX 2.0? If you do
this, I will wait until that moment to map my exceptions to those errors.
Right now in SqueakDBX you rise a generic OpenDBXException which has a
instance variable which is the number.
But, perhaps, if a future I want to reify the exceptions, for example
OpenDBXNoMemoryException. For that work, I think I will wait for OpenDBX 2.0
if they numbers won't change.
Best,
