TBufferXML Class Referencefinal

Class for serializing/deserializing object to/from xml.

The simple way to create XML representation is:

TNamed *obj = new TNamed("name", "title");
static TString ToXML(const T *obj, Bool_t GenericLayout=kFALSE, Bool_t UseNamespaces=kFALSE)
Definition TBufferXML.h:47
The TNamed class is the base class for all named ROOT classes.
Definition TNamed.h:29
Basic string class.
Definition TString.h:136

Produced xml can be decoded into new object:

TNamed *obj2 = nullptr;
static Bool_t FromXML(T *&obj, const char *xml, Bool_t GenericLayout=kFALSE, Bool_t UseNamespaces=kFALSE)
Definition TBufferXML.h:57

TBufferXML class uses streaming mechanism, provided by ROOT system, therefore most of ROOT and user classes can be stored to xml. There are limitations for complex objects like TTree, which can not be converted to xml.

Definition at line 33 of file TBufferXML.h.

Constructor & Destructor Documentation

◆ TBufferXML() [1/2]

TBufferXML::TBufferXML ( TBuffer::EMode  mode)

Creates buffer object to serialize/deserialize data to/from xml.

Mode should be either TBuffer::kRead or TBuffer::kWrite.

Definition at line 59 of file TBufferXML.cxx.

◆ TBufferXML() [2/2]

TBufferXML::TBufferXML ( TBuffer::EMode  mode,
TXMLFile file 
)

Creates buffer object to serialize/deserialize data to/from xml.

This constructor should be used, if data from buffer supposed to be stored in file. Mode should be either TBuffer::kRead or TBuffer::kWrite.

Definition at line 68 of file TBufferXML.cxx.

◆ ~TBufferXML()

TBufferXML::~TBufferXML ( )
virtual

Member Function Documentation

◆ BeforeIOoperation()

void TBufferXML::BeforeIOoperation ( )
protected

Function is called before any IO operation of TBuffer Now is used to store version value if no proper calls are discovered.

Definition at line 1394 of file TBufferXML.cxx.

◆ CheckVersionBuf()

void TBufferXML::CheckVersionBuf ( )
protected

Checks buffer, filled by WriteVersion if next data is arriving, version should be stored in buffer.

Definition at line 1461 of file TBufferXML.cxx.

◆ ClassBegin()

void TBufferXML::ClassBegin ( const TClass cl,
Version_t  = -1 
)
finalvirtual

Should be called at the beginning of custom class streamer.

Informs buffer data about class which will be streamed now. ClassBegin(), ClassEnd() and ClassMemeber() should be used in custom class streamers to specify which kind of data are now streamed. Such information is used to correctly convert class data to XML. Without that functions calls classes with custom streamers cannot be used with TBufferXML

Implements TBuffer.

Definition at line 1049 of file TBufferXML.cxx.

◆ ClassDefOverride()

TBufferXML::ClassDefOverride ( TBufferXML  ,
 
)
protected

◆ ClassEnd()

void TBufferXML::ClassEnd ( const TClass )
finalvirtual

◆ ClassMember()

void TBufferXML::ClassMember ( const char *  name,
const char *  typeName = nullptr,
Int_t  arrsize1 = -1,
Int_t  arrsize2 = -1 
)
finalvirtual

Method indicates name and typename of class member, which should be now streamed in custom streamer.

Following combinations are supported:

  1. name = "ClassName", typeName = 0 or typename==ClassName. This is a case, when data of parent class "ClassName" should be streamed. For instance, if class directly inherited from TObject, custom streamer should include following code:
    b.ClassMember("TObject");
    TObject::Streamer(b);
    #define b(i)
    Definition RSha256.hxx:100
  2. Basic data type
    b.ClassMember("fInt","Int_t");
    b >> fInt;
  3. Array of basic data types
    b.ClassMember("fArr","Int_t", 5);
    b.ReadFastArray(fArr, 5);
  4. Object as data member
    b.ClassMemeber("fName","TString");
    fName.Streamer(b);
  5. Pointer on object as data member
    b.ClassMemeber("fObj","TObject*");
    b.StreamObject(fObj);

Arrsize1 and arrsize2 arguments (when specified) indicate first and second dimension of array. Can be used for array of basic types. See ClassBegin() method for more details.
