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:
To reconstruct object from the JSON string, one should do:
JSON 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.
All STL containers by default converted into JSON Array. Vector of integers:
Will produce JSON code "[1, 4, 7]".
There are special handling for map classes like map
and multimap
. They will create Array of pair objects with "first" and "second" as data members. Code:
Will generate json string:
In special cases map container can be converted into JSON object. For that key parameter must be std::string
and compact parameter should be 5. Like in example:
Will produce JSON output:
Another possibility to enforce such conversion - add "JSON_object" into comment line of correspondent data member like:
