[Zope] Unique id product

[Sin Hang Kin]

Hi,

I want to develope a unique sequence id generator product, I have the
following code

    def newid(self, increment=1):
        """ return new id """
        self.counter = self.counter+increment
        return self.counter

I am not quite sure if this works when more than one process asking for a
newid concurrently. Is that zodb automatically serial all transaction?

BTW, how can I obtain a local copy of the zodb uml model?


Rgs,
