StateVarView(3U)

💖 StateVarView(3U) 💖

okay bestie, welcome to the InterViews Reference Manual — this is the tea on StateVarView, the state variable view base class. yes it's a whole vibe, yes it's abstract, let's get into it 🫶

✨ SYNOPSIS ✨

#include <Unidraw/stateview.h>

🌸 DESCRIPTION 🌸

so StateVarView is the base class for state variable views, periodt. and what do state variable views do? they hand you a whole graphical interface for examining — and maybe even modifying — a state variable subject. main character energy fr 💅

the StateVarView base class is an abstract class derived from MonoScene. and just like MonoScene, you do not instantiate StateVarView itself, no cap. instead, subclasses bring their own state and behavior that's actually appropriate for displaying and editing their subject. and like the other MonoScene subclasses out there, StateVarView subclasses use an interactor composition to define their appearance. iconic behavior honestly ✨

👑 PUBLIC OPERATIONS 👑

• virtual void Update() — updates the state variable view whenever a change happens in the state it depends on (usually the subject's state, iykyk). ngl you normally don't need to redefine this one if you've already redefined Init and Stale (both described down below 💖).

🎀 PROTECTED OPERATIONS 🎀

• StateVarView(StateVar*) — subclass constructors usually take an instance of the corresponding subject as an argument. and the base class constructor? it automatically attaches the view to the subject for you. no extra work, slay 🫶
• virtual void Init() — initializes the view based on the info living inside the subject. subclasses redefine this according to their own semantics, because everyone's different bestie. by default? it does nothing at all 🙈.
• virtual boolean Stale() — returns whether the view is in any way inconsistent with its subject. by default this operation always returns true (yes, always, it's giving paranoid). subclasses can redefine it to make a more discerning decision, which is lowkey the move ⭐.
