createPersistent()

template<class TPCNV , typename std::enable_if_t< std::is_base_of_v< ITPConverter, TPCNV > > * = nullptr>

std::unique_ptr<typename TPCNV::Pers_t> AthenaPoolCnvSvc::createPersistent	(	TPCNV &	cnv,
		const typename TPCNV::Trans_t *	transObj,
		const std::string &	key,
		MsgStream &	log
	)

Create a persistent object from a transient object.

Parameters

cnv	The TP converter to call.
transObj	The transient object to convert.
The	SG key of the object.
log	For logging messages.

This version is used when CNV derives from ITPConverter. We call TPCNV::createPersistentWithKey().

Parameters

cnv	The TP converter to call.
transObj	The transient object to convert.
The	SG key of the object.
log	For logging messages.

This version is used when CNV does not derivce from ITPConverter. We create the persistent object directly and call TPCnv::transToPers().

Definition at line 53 of file T_AthenaPoolCreateFuncs.h.

{
  return std::unique_ptr<typename TPCNV::Pers_t>
    (cnv.createPersistentWithKey (transObj, key, log));
}

createTransient()

template<class TPCNV , typename std::enable_if_t< std::is_base_of_v< ITPConverter, TPCNV > > * = nullptr>

std::unique_ptr<typename TPCNV::Trans_t> AthenaPoolCnvSvc::createTransient	(	TPCNV &	cnv,
		const typename TPCNV::Pers_t *	persObj,
		const std::string &	key,
		MsgStream &	log
	)

Create a transient object from a persistent object.

Parameters

cnv	The TP converter to call.
persObj	The persistent object to convert.
The	SG key of the object.
log	For logging messages.

This version is used when CNV derives from ITPConverter. We call TPCNV::createTransientWithKey().

Parameters

cnv	The TP converter to call.
persObj	The persistent object to convert.
The	SG key of the object.
log	For logging messages.

This version is used when CNV does not derivce from ITPConverter. We create the transient object directly and call TPCnv::persToTrans().
