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");

Produced xml can be decoded into new object:

TNamed *obj2 = nullptr;

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.

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 58 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 67 of file TBufferXML.cxx.

◆ ~TBufferXML()

TBufferXML::~TBufferXML ( )
virtual

Destroy xml buffer.

Definition at line 85 of file TBufferXML.cxx.

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 1393 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 1460 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 1048 of file TBufferXML.cxx.

◆ ClassDefOverride()

TBufferXML::ClassDefOverride ( TBufferXML  ,
 
)
protected

◆ ClassEnd()

void TBufferXML::ClassEnd ( const TClass )
finalvirtual

Should be called at the end of custom streamer See TBufferXML::ClassBegin for more details.

Definition at line 1057 of file TBufferXML.cxx.

◆ 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);
  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.

Implements TBuffer.
