Is S.R.P related Code open source?

Unity has Open source it's Code of C#,
I am studying the new features of 2018 that Scriptable Render Pipeline
Does the related code is writen in C#,if it is,where are these code located in Unity's GitHub Project

The code like this:

Code (CSharp):

1. namespace UnityEngine.Experimental.Rendering
2. {
3.     //
4.     // 摘要:
5.     //     ///
6.     //     Defines a series of commands and settings that describes how Unity renders a
7.     //     frame.
8.     //     ///
9.     public abstract class RenderPipeline : IRenderPipeline, IDisposable
10.     {
11.         protected RenderPipeline();
12.  
13.         //
14.         // 摘要:
15.         //     ///
16.         //     When the IRenderPipeline is invalid or destroyed this returns true.
17.         //     ///
18.         public bool disposed { get; }
19.  
20.         public static event Action<Camera[]> beginFrameRendering;
21.         public static event Action<Camera> beginCameraRendering;
22.  
23.         //
24.         // 摘要:
25.         //     ///
26.         //     Call the delegate used during SRP rendering before a single camera starts rendering.
27.         //     ///
28.         //
29.         // 参数:
30.         //   camera:
31.         public static void BeginCameraRendering(Camera camera);
32.         //
33.         // 摘要:
34.         //     ///
35.         //     Call the delegate used during SRP rendering before a render begins.
36.         //     ///
37.         //
38.         // 参数:
39.         //   cameras:
40.         public static void BeginFrameRendering(Camera[] cameras);
41.         //
42.         // 摘要:
43.         //     ///
44.         //     Dispose the Renderpipeline destroying all internal state.
45.         //     ///
46.         public virtual void Dispose();
47.         //
48.         // 摘要:
49.         //     ///
50.         //     Defines custom rendering for this RenderPipeline.
51.         //     ///
52.         //
53.         // 参数:
54.         //   renderContext:
55.         //
56.         //   cameras:
57.         public virtual void Render(ScriptableRenderContext renderContext, Camera[] cameras);
58.     }
59. }

 

More specifically https://github.com/Unity-Technologies/ScriptableRenderPipeline/blob/master/LICENSE.md

As far as I can tell that licence wouldn't pass most definitions of "Open Source". However it is probably "open source enough" for learning about the inner workings.

(I wouldn't let your lawyers read the licence though - they would probably get the jitters about clause 1)
