TBufferJSON Class Reference

Class for serializing object to and from JavaScript Object Notation (JSON) format.

It creates such object representation, which can be directly used in JavaScript ROOT (JSROOT) for drawing.

TBufferJSON implements TBuffer interface, therefore most of ROOT and user classes can be converted into JSON. There are certain limitations for classes with custom streamers, which should be equipped specially for this purposes (see TCanvas::Streamer() as example).

To perform conversion into JSON, one should use TBufferJSON::ToJSON method:

TH1 *h1 = new TH1I("h1", "title", 100, 0, 10);
h1->FillRandom("gaus",10000);
TString json = TBufferJSON::ToJSON(h1);

To reconstruct object from the JSON string, one should do:

TH1 *hnew = nullptr;
TBufferJSON::FromJSON(hnew, json);
if (hnew) hnew->Draw("hist");

JSON data does not include stored class version, therefore schema evolution (reading of older class versions) is not supported. JSON should not be used as persistent storage for object data - only for live applications.

Constructor & Destructor Documentation

TBufferJSON()

TBufferJSON::TBufferJSON

(

TBuffer::EMode

mode = TBuffer::kWrite

)

Creates buffer object to serialize data into json.

Definition at line 368 of file TBufferJSON.cxx.

~TBufferJSON()

TBufferJSON::~TBufferJSON ( )

virtual

Member Function Documentation

AppendOutput()

void TBufferJSON::AppendOutput ( const char *  line0, const char *  line1 = nullptr  )

protected

Append two string to the output JSON, normally separate by line break.

Definition at line 947 of file TBufferJSON.cxx.

ClassBegin()

void TBufferJSON::ClassBegin ( const TClass *  cl, Version_t  = -1  )

virtual

Should be called in the beginning of custom class streamer.

Informs buffer data about class which will be streamed now.

ClassBegin(), ClassEnd() and ClassMember() 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 JSON. Without that functions calls classes with custom streamers cannot be used with TBufferJSON

Implements TBuffer.

Definition at line 1844 of file TBufferJSON.cxx.

ClassEnd()

void TBufferJSON::ClassEnd ( const TClass *  )

virtual

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

Implements TBuffer.

Definition at line 1853 of file TBufferJSON.cxx.

ClassMember()

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

virtual

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.ClassMember("fName","TString");
   fName.Streamer(b);

5. Pointer on object as data member

   b.ClassMember("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.
