Detailed Description

ByteStream converter for the CTP_RDO object.

   This is a quite standard BS converter for the output sent from the
   Central Trigger Processor to the DAQ. It uses an external tool
   (CTPByteStreamTool) to do the actual work of the conversion, this
   converter is "only" supposed to communicate with the framework.

◆ createObj()
