I am not sure I understand why do you want to add Delegate in the class name.
Perhaps just VrContentViewCoreImpl?

[mthiesse, 2016/09/21 17:43:27]

Also, we're not implementing a ContentViewCore. Why not call this
VrInputManagerImpl?

+ public:
+  VrContentViewCoreImplDelegate(ContentViewCore* content_view_core);

nit: explicit

[asimjour, 2016/09/22 14:48:37]

Done.

+
+  static VrContentViewCoreImplDelegate* FromContentViewCore(
+      ContentViewCore* content_view_core);
