They must be using injectors, of course. No need for factories. I more surprised by the absence of XXXManager, XXXStore, XXXProvider, and also AbstractXXX, not to mention XXXStoreProvider and XXXStoreManager, and maybe DefaultXXXManager too (which is the default implementation of XXXManager (which is an interface), and also the only implementation of XXXManager that will ever exist by virtue of XXXManager being incredibly specific anyway).
