Type.createClass(
'Gemstone.Communication.UdpServer',
Gemstone.Communication.ServerBase);
Use UdpServer when the primary purpose is to transmit data.
The Server socket can be bound to a specified interface on a machine with multiple interfaces by specifying the interface in the ConfigurationString (Example: "Port=8888; Clients=localhost:8989; Interface=127.0.0.1")
The Server socket can be used just for transmitting data without being bound to a local interface by specifying -1 for the port number in the ConfigurationString (Example: "Port=-1; Clients=localhost:8989")
