AbstractRouter implements an abstract router that determines the destination address of the server-side connection. Service definitions should refer to a customized class derived from AbstractRouter, or one of the predefined router classes, such as TransparentRouter or DirectedRouter. Different implementations of this interface perform Transparent routing (directing the client to its original destination), and Directed routing (directing the client to a given destination).

A proxy can override the destination selected by the router using the the setServerAddress method.
