Where's AnimatorClipInfo?

According to this:

http://docs.unity3d.com/ScriptReference/Animator.GetCurrentAnimationClipState.html

public AnimatorClipInfo[] GetCurrentAnimationClipState(int layerIndex);

So I try to do:

AnimatorClipInfo[] clipInfos = MyAnimator.GetCurrentAnimationClipState (0);

And the compiler keeps complaining about "The type or namespace name `AnimatorClipInfo' could not be found. Are you missing a using directive or an assembly reference?"

It is a MonoBehaviour C# scripts that includes:

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System.Text;

I think it should be right in UnityEngine, but it doesn't seem to be the case...

Do you know where is it?

PS. This is in Unity 4.6, it seems in 5.x this whole thing have disappeared but I am not migrating to 5.0 anytime soon.

 

Ok, I realized the documentation is wrong. Such function actually returns AnimationInfo, not AnimatorClipInfo type.

Thanks for nothing.
