Member Function Documentation

createTransient()

template<class CNV , class TRANS >

std::unique_ptr<Trans_t> AthenaPoolCnvSvc::TPCnvElt< CNV, T_TPCnvNull< TRANS > >::createTransient	(	CNV &	parent,
		const std::string &	key,
		MsgStream &	msg
	)

Read the persistent object and convert it to transient.

Parameters

parent	The top-level pool converter object.
key	The SG key of the object being read.
msg	MsgStream for error reporting.

Returns a newly-allocated object. If the type of the persistent object on the file does not match the type that this converter handles, return nullptr. Other errors are reported by raising exceptions.

persToTrans()

template<class CNV , class TRANS >

bool AthenaPoolCnvSvc::TPCnvElt< CNV, T_TPCnvNull< TRANS > >::persToTrans	(	CNV &	parent,
		Trans_t *	trans,
		const std::string &	key,
		MsgStream &	msg
	)

Read the persistent object and convert it to transient.

Parameters

parent	The top-level pool converter object.
trans	The transient object to modify.
key	The SG key of the object being read.
msg	MsgStream for error reporting.

Overwrites the provided transient object. If the type of the persistent object on the file does not match the type that this converter handles, returns false. Other errors are reported by raising exceptions.
