State<T> class
abstract
The base class to represent State in an object.
This is the smallest representation of state in the Pheasant Framework. It is a generic class containing base functionality used to represent how state is controlled and managed in an application.
In this base class, we get to see a small representation of state management via the implementation of initValue, currentValue and previousValue, as well as the function change.
This class is extended, implemented and used in other classes for state control, and is directly used by StateObject, where most of the defined functions are implemented.
