StatusCode RootCalBaseCnv::createObj (  IOpaqueAddress *  addr, DataObject *&  refpObject )  [virtual, inherited]

Create the transient representation of an object, given an opaque address. This and the following update method comprise the core functionality of calibration converters. { // StatusCode ret; // first do the things we always need: // First string parameter of opaque address is file ident MsgStream log(msgSvc(), "RootCalBaseCnv"); log << MSG::DEBUG<<"RootCalBaseCnv::createObj( starting ...."<<endreq; const std::string* par = addr->par(); std::string par0 = par[0]; return internalCreateObj(par0, refpObject, addr); }

StatusCode RootEmcCalibDataCnv::createRoot (  const std::string &  fname, CalibData::CalibBase1 *  pTDSObj )  [virtual]

Create ROOT file corresponding to TDS object input. Default implementation is to return an error. Must be separately implemented for each calibration type. Parameters: fname  Filename for output file pTDSObj  Pointer to tds object to be converted Reimplemented from RootCalBaseCnv. { MsgStream log(msgSvc(), "RootEmcCalibDataCnv"); // Open the file, create the branch StatusCode sc = openWrite(fname); if(!sc) { log<<MSG::ERROR<<"unable to open files"<<endreq; } // write the Data in the TCDS to RootFile CalibData::EmcCalibData* tmpObject = dynamic_cast<CalibData::EmcCalibData*>(pTDSObj); int tmpNo; double EmcCalibConst; int EmcIxtalNumber; int i; //DigiCalibConst------------------------------------------------------------------ TTree *Digitree = new TTree("DigiCalibConst", "DigiCalibConst"); Digitree -> Branch("DigiCalibConst", &EmcCalibConst, "EmcCalibConst/D"); Digitree -> Branch("IxtalNumber", &EmcIxtalNumber, "IxtalNumber/I"); tmpNo = tmpObject -> getDigiCalibConstNo(); for(i=0; i<tmpNo; i++){ EmcCalibConst = tmpObject -> getDigiCalibConst(i); EmcIxtalNumber = tmpObject -> getIxtalNumber(i); Digitree -> Fill(); } Digitree -> Write(); delete Digitree; closeWrite(); log<<MSG::INFO<<"successfully create RootFile"<<endreq; return sc; }

StatusCode RootCalBaseCnv::fillRoot (  CalibData::CalibBase *  pTDSObj, TObject *  pRootObj )  [protected, virtual, inherited]

Given a pointer to a TDS object which can be cast to "our" type, fill in corresponding information in the corresponding root class Parameters: pTDSObj  Pointer to tds object to be converted pRootObj  Pointer to destination root object ...maybe don't need pRootObj argument; keep this as the (protected) data member m_rootObj. Or else this routine could set the protected member to this passed-in value { // Get instrument name from InstrumentName service Now handled by // RootCalBaseCnv // TString instr = TString((m_instrSvc->getInstrumentName()).c_str()); // pRootObj->setInstrument(instr); return StatusCode::SUCCESS; }

StatusCode RootCalBaseCnv::finalize (   )  [virtual, inherited]

{ return Converter::finalize(); }

ICalibRootSvc* RootCalBaseCnv::getCalibRootSvc (   )  [inline, inherited]

{ return m_rootSvc; }

StatusCode RootEmcCalibDataCnv::i_createObj (  const std::string &  fname, DataObject *&  refpObject )  [protected, virtual]

This creates the transient representation of an object from the corresponding ROOT object. This actually does the "new" operation and deals with the attributes of the node. This base class implementation does nothing; it should not normally be called because it doesn't correspond to any TCDS class. Instead, i_createObj of some derived class will be called. Parameters: fname  The ROOT file to be read in to be used to builds the object refpObject  the object to be built Returns: status depending on the completion of the call Reimplemented from RootCalBaseCnv. { MsgStream log(msgSvc(), "RootEmcCalibDataCnv"); log<<MSG::DEBUG<<"SetProperty"<<endreq; StatusCode sc = openRead(fname); if(!sc) { log<<MSG::ERROR<<"unable to open files"<<endreq; } CalibData::EmcCalibData *tmpObject = new CalibData::EmcCalibData ; // Read in our object int i; int nentries; // read DigiCalibConst ------------------------------------------------------------ double EmcCalibConst[6240]; int EmcIxtalNumber[6240]; vector<double> DigiCalibConst; vector<int> IxtalNumber; TTree *Digitree = (TTree*)m_inFile -> Get("DigiCalibConst"); Digitree -> SetBranchAddress("DigiCalibConst", EmcCalibConst); Digitree -> SetBranchAddress("IxtalNumber", EmcIxtalNumber); Digitree -> GetEntry(0); for(i=0; i<6240; i++){ DigiCalibConst.push_back(EmcCalibConst[i]); IxtalNumber.push_back(EmcIxtalNumber[i]); } tmpObject -> setDigiCalibConst(&DigiCalibConst); tmpObject -> setIxtalNumber(&IxtalNumber); refpObject=tmpObject; return StatusCode::SUCCESS; }

StatusCode RootCalBaseCnv::i_processObj (  DataObject *  pObject, IOpaqueAddress *  address )  [protected, virtual, inherited]

In case there is additional work to do on the created object. { return StatusCode::SUCCESS; }

StatusCode RootCalBaseCnv::initialize (   )  [virtual, inherited]

{ StatusCode status = Converter::initialize(); IDataProviderSvc* dp; // I guess the service names are assigned in jobOptions? serviceLocator()->getService ("CalibDataSvc", IID_IDataProviderSvc, (IInterface*&)dp); setDataProvider(dp); // Locate the Root Conversion Service serviceLocator()->getService ("CalibRootCnvSvc", IID_ICalibRootSvc, (IInterface*&) m_rootSvc); // Locate meta conversion service // Will anything need to be changed here to accommodate possibility // of two concrete implementations of ICalibMetaCnvSvc? Would // have different storage types. Could specify type desired // as job option. Ditto for name of class? serviceLocator()->getService("CalibMySQLCnvSvc", IID_ICalibMetaCnvSvc, (IInterface*&)m_metaSvc); serviceLocator()->getService ("CalibDataSvc", IID_IInstrumentName, (IInterface*&)m_instrSvc); return status; }

StatusCode RootCalBaseCnv::internalCreateObj (  const std::string &  fname, DataObject *&  refpObject, IOpaqueAddress *  address )  [protected, virtual, inherited]

This creates the transient representation of an object from the corresponding ROOT object it, then fills it and process it. This implementation actually only calls the i_* methods of the "right" converter to do the job; so the very first thing it does is get a pointer to the appropriate derived converter. Converters typically don't need to override this method but only to override/implement some of the i_* methods. Parameters: pRootObj  pointer to the ROOT object refpObject  the object to be built address  the opaque address for this object Returns: status depending on the completion of the call { MsgStream log(msgSvc(), "RootCalBaseCnv"); log << MSG::DEBUG<<"RootCalBaseCnv::internalCreateObj( starting ..... "<<endreq; RootCalBaseCnv* converter = this; CLID classId = address->clID(); IConverter* conv = this->conversionSvc()->converter(classId); if (0 == conv) { log << MSG::WARNING << "No proper converter found for classID " << classId << ", the default converter" << " will be used. " << endreq; } else { converter = dynamic_cast <RootCalBaseCnv*> (conv); if (0 == converter) { log << MSG::ERROR << "The converter found for classID " << classId << " was not a descendent of RootCalBaseCnv as it should be " << "( was of type " << typeid (*converter).name() << "). " << "The default converter will be used" << endreq; converter = this; } } m_runfrm =*( address->ipar()); m_runto =*( address->ipar()+1); // creates an object for the node found StatusCode sc = converter->i_createObj(fname, refpObject); if (sc.isFailure()) { return sc; } CalibData::CalibBase1* tmpObject = dynamic_cast <CalibData::CalibBase1*> (refpObject); setBaseInfo(tmpObject); // ends up the object construction sc = converter->i_processObj(refpObject, address); if (sc.isSuccess()) { log << MSG::DEBUG << "Successfully created calib. object " << endreq; } closeRead(); return sc; }

StatusCode RootCalBaseCnv::openRead (  const std::string &  fname  )  [protected, inherited]

Utility for "leaf" converters to call Parameters: Root  file to open for read Name  of branch to be read in ref.  to pCalib pointer which will be set to address of read-in object { MsgStream log(msgSvc(), "RootCalBaseCnv"); // Check fname isn't empty if (fname == std::string("")) return StatusCode::FAILURE; if (doClean() ) { log << MSG::WARNING << "Previous operation didn't clean up!
