Last change on this file since 15658 was 13836, checked in by tbretz, 12 years ago
Added some workaround to make these classes not derive from DimInfoHandler - this clashes with the new StateMachineDim -- this must be fixed, it is still asnychronous with the event loop\!

42
43@brief Implements automatic subscription to MESSAGE and STATE services
44
45This class derives from DimServiceInfoList, so that it has a full
46overview of all commands and services existing in the current Dim
47network. In addition it automatically subscribes to all available
48MESSAGE and STATE services and redirects them to its MessageImp base class.
49
50@todo
51- maybe the StateClient can be abondoned, this way it would be possible
52 to subscribe to only available MESSAGE and STATE services
