Annotation Interface Initialized

This type qualifier belongs to the freedom-before-commitment initialization tracking type-system. This type-system is not used on its own, but in conjunction with some other type-system that wants to ensure safe initialization. For instance, NullnessChecker uses freedom-before-commitment to track initialization of NonNull fields.

This type qualifier indicates that the object has been fully initialized; reading fields from such objects is fully safe and yields objects of the correct type.
