Part of fixture.loadable.loadable.LoadableFixture View In Hierarchy
"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.
|Method||register||register this object as "loaded" at level|
|Method||referenced||tell the queue that this object was referenced again at level.|
|Method||to_unload||yields a list of objects suitable for unloading.|
