Please document the type of this field, and indicate the meaning of it being
nullable. I kind of expected this to be a normal two-state boolean until I saw
line 119. Alternatively, consider renaming it to |permissionStatus_| and make it
of type nullable PermissionStatus.

[Sam McNally, 2016/05/05 11:50:23]

Changed to a PermissionStatus, using PermissionStatus.ASK instead of null.

Why doesn't this method need to be implemented? Are we missing test coverage?

[Sam McNally, 2016/05/05 11:50:23]

We're missing test coverage. I've copy-pasted the FIXME from the C++ mock now.
