Probably should say "final" instead of "override"; same for most other functions in the file.

Extra blank line here; should not add that.

Ditto.

> +    Vector<PlatformMediaSession*> sessionList = sessions();

I think auto would be better here than writing out the vector type. Actually, we could evaluate the vector inside the for loop:

    for (auto session : sessions()) {

That would work with no local variable.

This isn’t needed. It doesn’t optimize anything.
