Unused?

[lgarron, 2015/06/09 18:51:23]

Indeed. It'll be needed later, but I've removed it anyhow.

virtual

[lgarron, 2015/06/09 18:51:23]

Are you saying I should make it virtual?

Other handlers are inconsistent about whether to mark this as `virtual`,
`override`, or neither.

[pfeldman, 2015/06/09 19:04:23]

virtual for now, change to override later.

Sorry, I should have been more specific in my last comment. I think we *do* need
a SetClient() method here (since generated code will attempt to call it:
https://code.google.com/p/chromium/codesearch#chromium/src/out/Debug/gen/cont...).
But SetClient() can't take a devtools::security::Client as an argument because
that class isn't defined yet. Instead, I guess it should take a
scoped_ptr<DevToolsProtocolClient*> as an argument (which is the base class of
the devtools::*::Client classes), and we can change that to a
devtools::security::Client once the protocol.json changes land.

This is a good point - you need a generic SetClient for the first commit.
