Shouldn't this CL also include an implementation of this method?

This is a mojo interface definition file. The implementation is auto-generated
by mojo framework.

[Luis Héctor Chávez, 2016/04/19 22:33:35]

For future reviews: All methods in components/arc/common/ that are defined in an
*Instance interface do not have an implementation in Chrome-side, only the ones
defined in *Host. ARC-side is the opposite.
