| Store | | public interface Store (Code) | | A Store is the abstraction of a Catalina component that provides
persistent storage and loading of Sessions and their associated user data.
Implementations are free to save and load the Sessions to any media they
wish, but it is assumed that saved Sessions are persistent across
server or context restarts.
