InitialData<D> class
sealed
A callable class that can produce the initial data value for a data state, when the state is entered.
Constructors
- InitialData.new(D create())
-

createfunction to obtain the initial data value. The function is called each time the data state is entered.factory -
InitialData.run(GetInitialData<
D?> getInitialData) -
Creates an InitialData that will call the
getInitialDatafunction, passing the TransitionContext for the transition in progress, to obtain the initial data value. The function is called each time the data state is entered.factory - InitialData.value(D value)
-
