The Visitor pattern is extremely handy. tiOPF use in for so much, from
find objects, changing properties over many objects, processing what
objects need to be loaded or saved to/from a persistence layer etc...

tiOPF was designed for Object Persistence, but it has grown to have so
many nice features and utilities, I find myself often using the base
classes (or some other features like Logging) of tiOPF for non-db
projects too.
