class Folded[Obs, A, T, U] extends ActionValueFn[Obs, A, U]

ActionValueFn implementation that implements a fold.

Any value supplied to update will be transformed first by prepare before being passed to the base ActionValueFn. Any value retrieved by actionValue will be passed to present before being returned.

    Transforms this ActionValueFn into a new instance that applies the supplied prepare to all incoming values before they're learned, and presents tracked T instances using the present fn before returning them via actionValue.
