[Unity] ServiceLocatorManager > 구조 변경 / indexer, Type

일단은 서비스 딕셔너리를 생성해준 후 indexer로 Type 값을 반환한다

여기서 instance는 싱글톤 객체를 의미한다

private Dictionary<Type, object> _services = new Dictionary<Type, object>();

public object this[Type type]
{
    get
    {
        if (_services.TryGetValue(type, out object service))
            return service;
        
        Debug.LogWarning($"Service of type {type.Name} not found!");
        return null;
    }
    set
    {
        if (_services.ContainsKey(type))
        {
            Debug.LogWarning($"Service of type {type.Name} already registered. Overwriting...");
            _services[type] = value;
        }
        else
        {
            _services.Add(type, value);
            Debug.Log($"Service of type {type.Name} registered successfully.");
        }
    }
}

 

자주 쓰여지는 것들은 아래 함수들을 활용하면 된다

public static object GetInstance(Type type) =>instance[type];

public static T GetInstance<T>() where T : class => HasInstance<T>() ? instance.Get<T>()  : null;

public static void RegisterInstance<T>(T service) where T : class => instance.Register(service);

public static void UnregisterInstance<T>() where T : class => instance.Unregister<T>();

public static bool HasInstance<T>() where T : class => instance.HasService<T>();

이렇게 활용하면 된다

ServiceLocatorManager.GetInstance<PlayerController>();

 

자주 안쓰여지는것들은 instance. 해도 무방하다

public void Register<T>(T service) where T : class
{
    Type type = typeof(T);
    this[type] = service;
}

public T Get<T>() where T : class
{
    Type type = typeof(T);
    object service = this[type];
    return service as T;
}

public void Unregister<T>() where T : class
{
    Type type = typeof(T);
    if (_services.ContainsKey(type))
    {
        _services.Remove(type);
        Debug.Log($"Service of type {type.Name} unregistered.");
    }
}

public bool HasService<T>() where T : class => _services.ContainsKey(typeof(T));

public void ClearAll()
{
    _services.Clear();
    Debug.Log("All services cleared.");
}
