Class f.l.l.L.LoadQueue(ObjRegistry):

Part of fixture.loadable.loadable.LoadableFixture View In Hierarchy

Keeps track of what class instances were loaded.

"level" is used like so:

The lower the level, the lower that object is on the foreign key chain. As the level increases, this means more foreign objects depend on the local object. Thus, objects need to be unloaded starting at the lowest level and working up. Also, since objects can appear multiple times in foreign key chains, the queue only acknowledges the object at its highest level, since this will ensure all dependencies get unloaded before it.
