class WebBrowserImpl.WebBrowserImpl(system, config)

Defines an abstract class that provides a common interface to all web browsers the User knows how to use. Subclasses of this class will implement actual interaction with real browsers.

Parameters:

  • system: a <no title> object which lets us control the remote system

  • config: a <no title> object defining the current user
