Strangely, I find myself at a crossroads where I would like to have
static (i.e. per-module) variables. Yes -- I know -- this would be a
gross violation of the shared-nothing principle -- but then I would be
just as happy if all static variables were "final" so there's no way
that two processes would trample on the same data.
The situation is actually pretty simple: I have a 'person' module that
corresponds to a database table. This module has a (static) list of
fields. I would like to be able to access this static list from the
module's functions without having to reconstruct it inside the
function every time by calling a function such as
Here's basically what I want to have:
fields = ["name", "age"].
Is there any way to do this in Erlang???
(I looked at the process dictionary, but it is per process, not per module).
