All of the persistent objects in Engine implement the QOFObject interface which QOFQuery uses, so it's available for Budgets regardless of whether the gnc-budget code uses it. You must *not* look at code in src/engine for examples of what to do: That code is private and is going to change a *lot* in the coming dev cycle. Look instead at src/report. I can't be certain that we'll get to replacing QOFQuery in this cycle, but we will eventually replace it with SQL when we migrate to using the database as a database instead of a mere persistence store, so be sure to abstract your query code so that it can be easily replaced.
