// Encapsulates platform-specific functionality for observing events that may

// will be called when an event happens that could result in a state change.
// The incognito state should then be checked by the callback.
// TODO(asvitkine): Considering moving the check for incognito to this class
// too; see ChromeMetricsServicesManagerClient::IsIncognitoSessionActive().
