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.

Constructor & Destructor Documentation

CTPByteStreamCnv()

CTPByteStreamCnv::CTPByteStreamCnv

(

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 CTPByteStreamCnv::classID ( )

static

Function needed by the framework.

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

Definition at line 36 of file CTPByteStreamCnv.cxx.

                               {

createObj()

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

overridevirtual

Function creating the CTP_RDO object from a CTP ROB fragment.

This function creates the CTP_RDO object from the BS data.

It requests the ROB fragment with the ROB Id of the CTP and gives this fragment to the CTPByteStreamTool for conversion.

createRep()

StatusCode CTPByteStreamCnv::createRep ( DataObject * pObj, IOpaqueAddress *& pAddr )

overridevirtual

Function creating the CTP ROB fragment from a CTP_RDO object.

This function receives a CTP_RDO object as input, and adds the ROB fragment of the CTP to the current raw event using the IByteStreamEventAccess interface.
