SimpleMessage: A performant alternative to SendMessage in Unity. (A simple wrapper around the Unity UI event system)

SimpleMessage.cs

using UnityEngine;
using UnityEngine.EventSystems;

public static class SimpleMessage
{
  public delegate void EventFunction<T1,T2>(T1 handler, T2 eventData);

  public static bool Send<T,T2>(GameObject target, object eventData, EventFunction<T, T2> functor)
      where T : IEventSystemHandler
  {
      return ExecuteEvents.Execute<T>(target, null, (x, y) => functor(x, (T2)eventData));
  }

  public static void SendHierarchy<T, T2>(GameObject root, object eventData, EventFunction<T,T2> functor) where T : IEventSystemHandler
  {
      ExecuteEvents.ExecuteHierarchy<T>(root, null, (x, y) => functor(x, (T2)eventData));
  }
}
