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... > Guess I need to study tiOPF finally. It is on my ToDo list anyway. 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.
