All Implemented Interfaces:

java.lang.Runnable

Direct Known Subclasses:

CityProxy.TCPHandlerVee

Enclosing class:

CityProxy

protected class CityProxy.TCPHandlerDub

extends CityProxy.TCPHandlerAna

handler for TCP connection to WWW visitor client (dub)

receives position ($P), orientation ($C) and user ($U) messages and sends optional visitor ($V) and refresh ($R) messages and EOM message ($S)

maintains list of visitors by listening for Object3D events with name ending in "wand"
