is this being called from code that's outside of content (but not in the
chromium repo)?

[gone, 2012/06/29 21:59:10]

It hasn't been upstreamed, yet; the only place it's being called is under
content/browser/android/content_view_impl.cc
We're apparently doing some major refactoring here, though.

It pulls in the Controller from WebContentsImpl::GetController(), which returns
a regular NavigationController.  If we took in the NavigationControllerImpl
directly, we could probably avoid adding it to the public API, though the
ReloadType is likely going to have to stay.

[jam, 2012/06/29 22:58:58]

ok, in that case, it should be on the impl only (see
http://www.chromium.org/developers/content-module/content-api)

you can safetly cast from NavigationController to NavigationControllerImpl in
the code that calls this.

[gone, 2012/07/03 00:07:47]

Moved it over to the Impl.
