Class TangoConnectionFactory

java.lang.Object
  org.dawb.tango.extensions.factory.TangoConnectionFactory

public class TangoConnectionFactory
extends java.lang.Object

This class is designed to give: 1. a dummy connection or a tango one. 2. deal with the fact that you can only have one attribute class listening to a connection and parameter combination at a time. This allows a dummy mode to be used which is useful for testing as no spec motors will be moved by the tango service.
