Prf class abstract
Core service class that manages SharedPreferences initialization and access.
This abstract class cannot be instantiated directly and provides static methods to safely access the SharedPreferences instance.
The class implements:
- Lazy initialization (SharedPreferences are only loaded when first needed)
- Caching (the instance is stored after first retrieval)
- Thread-safety (initialization is protected against race conditions)
