Overview

This class is used to represent runtime settings that have not been initialized yet. You can use this to protect your application from accidentally accessing runtime settings before they are initialized. Doing this can cquse unexpected behavior if the runtime settings engine has not yet been initialized. For instance, if your runtime settings enging reads from a database it would not be available until the database connection is established.

The intention of this class is to set it a the runtime settings at the beginning of initialization and then set the actual runtime settings engine after the initialization is complete. It will act as a guard to prevent invalid runtime settings backed configurations from being used during initialization.
