Reaction works even without making [Atom]

[slimshader]

Hi,

is this a desired behaviour:

    [Atom]
    public string Name { get; set; }

    public bool IsNameValid => !string.IsNullOrEmpty(Name) && Name.Length > 3;

later:

        Atom.Reaction(Lifetime, () => _user.IsNameValid, x =>
        {
            Debug.Log($"IsNameValid: {x}");
            _nameLabel.style.color = x ? Color.green : Color.red;
        });

reaction is properly reacting even tho IsNameValid is not marked as [Atom].

If it is desired, then do I understand correcly that:

1. Reaction works because it registeres to underlying Name atom
2. because IsNameValid is not marked as [Atom] the result is not cashed for that property

Yes, this is intended behavior

• Right. Reactions are subscribed to every atom that have been read. In this case it is the Name. It does not matter how the atoms were read, directly or through multiple nested method calls
• Right. This is a regilar C# property and, accordingly, without a cache

For example, here if you do not specify the Atom attribute, the error log will be printed every second. With the attribute it will be printed only once since the result will be cached

using UniMob;
using UnityEngine;

public class AtomCaching : LifetimeMonoBehaviour
{
    [Atom] public int A { get; set; }
    [Atom] public int B { get; set; }

    /*[Atom]*/ public int Computed
    {
        get
        {
            Debug.LogError("Compute");
            return A;
        }
    }

    private void Awake()
    {
        Atom.Reaction(Lifetime, () => Debug.Log(Computed + B));

        InvokeRepeating(nameof(IncrementB), 1f, 1f);
    }

    private void IncrementB()
    {
        B++;
    }
}

I see, thanks againt for great explanation.

btw, UniMob starts to become a crucial library for me along UniTask and vContainer, I see a long future ahead ;)
