StateObject<T> class

This is the class that makes use of the State class, with proper definitions of overriden functions from State.

This class is used directly in other component state classes in instantiating state on a value, or variable defined with type T. The state of such variable is recorded by instantiating its initValue, and then updating the currentValue via changes recorded by change.

Concrete implementations of freeze, unfreeze and reload are given here.
