TStreamerInfo Class Reference

Describe Streamer information for one class version.

Describes a persistent version of a class.

A ROOT file contains the list of TStreamerInfo objects for all the class versions written to this file. When reading a file, all the TStreamerInfo objects are read back in memory and registered to the TClass list of TStreamerInfo. One can see the list and contents of the TStreamerInfo on a file with, e.g.,

TFile f("myfile.root");
f.ShowStreamerInfo();
#define f(i)
Definition: RSha256.hxx:104
A ROOT file is a suite of consecutive data records (TKey instances) with a well defined format.
Definition: TFile.h:48

A TStreamerInfo is a list of TStreamerElement objects (one per data member or base class). When streaming an object, the system (TClass) loops on all the TStreamerElement objects and calls the appropriate function for each element type.

◆ GetCheckSum() [2/2]

UInt_t TStreamerInfo::GetCheckSum ( TClass::ECheckSum  code) const

Recalculate the checksum of this TStreamerInfo based on its code.

The class ckecksum is used by the automatic schema evolution algorithm to uniquely identify a class version. The check sum is built from the names/types of base classes and data members. The valid range of code is determined by ECheckSum.

  • kNoEnum: data members of type enum are not counted in the checksum
  • kNoRange: return the checksum of data members and base classes, not including the ranges and array size found in comments.
  • kWithTypeDef: use the sugared type name in the calculation.

This is needed for backward compatibility.

WARNING

This function must be kept in sync with TClass::GetCheckSum. They are both used to handle backward compatibility and should both return the same values. TStreamerInfo uses the information in TStreamerElement while TClass uses the information from TClass::GetListOfBases and TClass::GetListOfDataMembers.

◆ GetStreamerElementReal()

TStreamerElement * TStreamerInfo::GetStreamerElementReal ( Int_t  i,
Int_t  j 
) const

Obsolete: this routine is obsolete and should not longer be used.

TStreamerInfo holds two types of data structures

  • TObjArray* fElements; containing the list of all TStreamerElement objects for this class version.
  • ULong_t* fElem; containing the preprocessed information by TStreamerInfo::Compile In case consecutive data members are of the same type, the Compile function declares the consecutive elements as one single element in fElems.

Example with the class TAttLine:

TClass::GetClass("TAttLine")->GetStreamerInfo()->ls(); produces;
StreamerInfo for class: TAttLine, version=1
short fLineColor offset= 4 type= 2 line color
short fLineStyle offset= 6 type= 2 line style
short fLineWidth offset= 8 type= 2 line width
i= 0, fLineColor type= 22, offset= 4, len=3, method=0

For I/O implementations (eg. XML) , one has to know the original name of the data member. This function can be used to return a pointer to the original TStreamerElement object corresponding to the j-th element of a compressed array in fElems. Parameters description:

  • i: the serial number in array fElem
  • j: the element number in the array of consecutive types In the above example the class TAttLine has 3 consecutive data members of the same type "short". Compile makes one single array of 3 elements. To access the TStreamerElement for the second element of this array, one can call:
    auto el = GetStreamerElementReal(0,1);
    auto membername = el->GetName();
    TStreamerElement * GetStreamerElementReal(Int_t i, Int_t j) const
    Obsolete: this routine is obsolete and should not longer be used.
    This function is typically called from TBuffer, TXmlBuffer.
