CheckClasses()

void TVirtualConverter::CheckClasses ( )

privateinherited

Helper to check that the classes have been defined properly.

Check that the class pointers got defined.

Definition at line 188 of file TVirtualConverter.cxx.

  if (fTransClass == nullptr) {
    if (fPersClass == nullptr)
      Error ("TVirtualConverter",
             "Both transient and persistent classes are null.");
    else
      Error ("TVirtualConverter",
             "Transient class is null for persistent class `%s'",

}

CheckStreamInfos()

void TVirtualConverter::CheckStreamInfos ( )

privateinherited

Helper to allow for automatic schema evolution for persistent classes.

Convert()

void TrigSpacePointCounts_p1_old_cnv::Convert ( TrigSpacePointCounts_p1 * transobj, const TrigSpacePointCounts_p1_old * persobj )

virtual

Do the conversion.

Parameters

transobj	Pointer to an instance of the transient class.
persobj	Pointer to an instance of the persistent class.

An implementation of this must be provided in derived classes. It should initialize the object at transobj from the one at persobj.

Implements TVirtualConverter_T< TrigSpacePointCounts_p1, TrigSpacePointCounts_p1_old >.

Definition at line 10 of file TrigSpacePointCounts_p1_old_cnv.cxx.

{
  newobj->m_pixSPcnt     = oldobj->m_pixcnt;
  newobj->m_sctSPcnt     = oldobj->m_sctcnt;
 
  newobj->m_pixCL1cnt    = 0;

}

ConvertVoid()

virtual void TVirtualConverter_T< TrigSpacePointCounts_p1, TrigSpacePointCounts_p1_old >::ConvertVoid ( void * transobj, const void * persobj )

virtualinherited

Do the conversion.

Parameters

transobj	Pointer to an instance of the transient class.
persobj	Pointer to an instance of the persistent class.

This implementation simply calls the Convert below with the appropriate casting.

Implements TVirtualConverter.

DeletePersObj()

void TVirtualConverter::DeletePersObj ( void * persobj )

virtualinherited

Destroy an instance of the persistent class.

Parameters

persobj

Pointer to the instance to destroy.

The provided implementation of this uses TClass::Destructor, but you can override it if need be.

Definition at line 263 of file TVirtualConverter.cxx.

{
  return fPersClass->Destructor (persobj);
}

GetCheckSum()

int TVirtualConverter::GetCheckSum ( ) const

inherited

Return the checksum of the class from which we're converting.

Definition at line 238 of file TVirtualConverter.cxx.

{
  return fCheckSum;
}

GetPersClass()

TClass * TVirtualConverter::GetPersClass ( )

inherited

Return the persistent class, from which we're converting.

Definition at line 229 of file TVirtualConverter.cxx.

{
  return fPersClass;
}

GetTransClass()

TClass * TVirtualConverter::GetTransClass ( )

inherited

Return the transient class, to which we're converting.

Definition at line 220 of file TVirtualConverter.cxx.

{
  return fTransClass;
}

NewPersObj()

void * TVirtualConverter::NewPersObj ( )

virtualinherited

Create a new instance of the persistent class.

The provided implementation of this uses TClass::New, but you can override it if need be.

Definition at line 250 of file TVirtualConverter.cxx.

{
  return fPersClass->New();
}

ReadBuffer()

void TVirtualConverter::ReadBuffer ( TBuffer & b, void * obj, Version_t version, UInt_t R__s, UInt_t R__c )

virtualinherited

Read object in non-split mode.

Parameters

b	The source of the data.
obj	The object into which we're reading. (This will be the transient object.)
version	The version number of the class.
R__s	The starting position in the buffer.
R__c	The number of bytes for this object in the buffer.

You normally shouldn't have to worry about this, but it's exposed here so that it can be overridden if needed. It's only used when reading in non-split mode.

Definition at line 282 of file TVirtualConverter.cxx.

{
  // Make sure that we've done automatic schema evolution on the
  // persistent side.
  CheckStreamInfos();
 
  // Make an instance of the persistent class, if we haven't done so already.
  if (fPersObj == nullptr)
    fPersObj = NewPersObj();
 
  // Read in the object, as an instance of the persistent class.
  fPersClass->ReadBuffer (b, fPersObj, version, R__s, R__c);
 
  // Convert to the transient representation.
  ConvertVoid (obj, fPersObj);
}

SetCtorInfo()

void TVirtualConverter::SetCtorInfo ( UInt_t checksum, TClass * trans_cls, TClass * pers_cls )

protectedinherited

ToClass() [1/2]

TClass * TVirtualConverter::ToClass ( const std::string & name )

staticinherited

Helper to convert a class name to a Root class pointer.

Parameters

name	The name of the class to convert.

Definition at line 310 of file TVirtualConverter.cxx.

{
  return gROOT->GetClass (name.c_str());
}

ToClass() [2/2]

TClass * TVirtualConverter::ToClass ( const std::type_info & id )

staticinherited

Helper to convert a type_info to a Root class pointer.

Parameters

name	The type_info of the class to convert.

Returns nullptr on failure.

Definition at line 322 of file TVirtualConverter.cxx.

{
  TClass* cl = gROOT->GetClass (id);
  if (cl) return cl;
 
  // This may fail if the dictionary hasn't been loaded yet,
  // since we can auto-load only on the name.
  // Make some attempt to get a name from the type_info.
  const char* name = id.name();
  cl = gROOT->GetClass (name);
  if (cl) return cl;
 
  const char* n2 = name;
  while (isdigit(*n2))

  {
    // Protect against data race inside TClassEdit.
    // https://github.com/root-project/root/issues/10353
