Detailed Description

ByteStream converter for the MuCTPI_RDO object.

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

Constructor & Destructor Documentation

MuCTPIByteStreamCnv()

MuCTPIByteStreamCnv::MuCTPIByteStreamCnv

(

ISvcLocator *

svcloc

)

Standard constructor.

The constructor sets up all the ToolHandle and ServiceHandle objects and initialises the base class in the correct way.

classID()

CLID MuCTPIByteStreamCnv::classID ( )

Function needed by the framework.

Function telling the framework the Class ID of the object that this converter is for (MuCTPI_RDO).

createObj()

StatusCode MuCTPIByteStreamCnv::createObj ( IOpaqueAddress * pAddr, DataObject *& pObj )

overridevirtual

Function creating the MuCTPI_RDO object from a MuCTPI ROB fragment.

This function creates the MuCTPI_RDO object from the BS data.

It requests the ROB fragment with the ROB Id of the MuCTPI and gives this fragment to the MuCTPIByteStreamTool for conversion.
