baseToPersistent()

template<class TRANS >

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

Definition at line 97 of file TPConverter.h.

                                                                                           {

CNV* ITPConverterFor< TRANS >::converterForRef ( CNV *  cnv, const TPObjRef &  ref, MsgStream &  log  ) const

HepMC::GenVertexPtr McEventCollectionCnv_p7::createGenVertex ( const McEventCollection_p7 &  persEvts, const GenVertex_p7 &  vtx, ParticlesMap_t &  bcToPart, HepMC::DataPool &  datapools, HepMC::GenEvent *  parent = nullptr  ) const

protected

Create a transient GenVertex from a persistent one (version 1) It returns the new GenVertex.

This method calls createGenParticle for each of the out-going particles and only for the in-going particle which are orphans (no production vertex): for optimisation purposes. Note that the map being passed as an argument is to hold the association of barcodes to particle so that we can reconnect all the (non-orphan) particles to their decay vertex (if any).
