Detailed Description

This Class implements an Parser, classes they inherit this, are able to "dock" on an IOBus. Its used for e.g. for RS-485 Communication busses, there may different devices on one bus. Its not pratcicable to wrote an huge extract_packed for this, each device can with this clas implement it's own extractor.

virtual

read packed calls the readPacked from IOBus, if this readPacked is used only the extract packed from this Device is called, other device-extractors are not involved, to no call to packedReady (see IOBusHandler) is done. If youre devices not request->answer like you need to use the IOBusHandler, and call the readPacked from IOBus.

Reimplemented in iodrivers_base::BusHandler.
