Class for serializing/deserializing object to/from xml.

The simple way to create XML representation is:

TNamed *obj = new TNamed("name", "title");

TString xml = TBufferXML::ToXML(obj);

TBufferXML::ToXML

static TString ToXML(const T *obj, Bool_t GenericLayout=kFALSE, Bool_t UseNamespaces=kFALSE)

Definition TBufferXML.h:47

TNamed

The TNamed class is the base class for all named ROOT classes.

Definition TNamed.h:29

TString

Basic string class.

Definition TString.h:139

Produced xml can be decoded into new object:

TNamed *obj2 = nullptr;

TBufferXML::FromXML(obj2, xml);

TBufferXML::FromXML

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.

◆ ClassBegin()

void TBufferXML::ClassBegin	(	const TClass *	cl,

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 1050 of file TBufferXML.cxx.

◆ ClassEnd()

	)

finalvirtual

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

Following combinations are supported:

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);

b
#define b(i)
Definition RSha256.hxx:100

TObject::Streamer
virtual void Streamer(TBuffer &)
Stream an object of class TObject.
Definition TObject.cxx:906
Basic data type
b.ClassMember("fInt","Int_t");

b >> fInt;
Array of basic data types
b.ClassMember("fArr","Int_t", 5);

b.ReadFastArray(fArr, 5);
Object as data member
b.ClassMemeber("fName","TString");

fName.Streamer(b);
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.
