Module: Queries .\src\TW\SEF\Queries.py

Simple predicate-driven query support oriented towards in-memory models

This module wants to be a much more general and powerful query framework for Python objects, but it's mostly based on code that pre-dates the availability of a decent Interface package, let alone the kind of interface adaptation that's really needed to do it right. Maybe as Zope 3X gets a little further along, I'll take a look at creating an enhanced version using interfaces and the adapter registry from the Zope Component Architecture. (If I have app(s) that need that sort of thing, that is.) Meanwhile, this is relatively unmaintained, except for what's needed to keep the unit tests running.
