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 in RootCorrectedETSCnv, RootDedxCalibDataCnv, RootDedxSimDataCnv, RootEmcCalibDataCnv, RootEsTimeCalibDataCnv, RootEstTofCalibDataCnv, RootInjSigIntervalCnv, RootInjSigTimeCnv, RootMdcCalibDataCnv, RootMucCalibDataCnv, RootOffEvtFilterCnv, RootTofCalibDataCnv, and RootTofSimDataCnv.

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

i_createObj()

StatusCode RootCalBaseCnv::i_createObj ( const std::string &  fname, DataObject *&  refpObject  )

protectedvirtual

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

internalCreateObj()

StatusCode RootCalBaseCnv::internalCreateObj ( const std::string &  fname, DataObject *&  refpObject, IOpaqueAddress *  address  )

protectedvirtual

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
