template<class CNV >

TPObjRef ITPConverterFor< TRANS >::baseToPersistent	(	CNV **	cnv,
		const typename CNV::Trans_t *	transObj,
		MsgStream &	log
	)		const

inlineinherited

Persistify bass class of a given object and store the persistent represenation in the storage vector of the top-level persistent object.

The converter is located using the transient type from the CNV parameter, not from the object itself (because we need the base type, not the actual type)

Parameters

cnv	[IN/OUT] type of this parameter decides which converter will be used. Once the converter is found, this pointer will be set so the search is done only once
transObj	[IN] transient object
log	[IN] output message stream

Returns: TPObjRef TP reference to the persistent representation stored in the storage vector of the top-level persistent object
