When using RooFit, statistical models can be conveniently handled and stored as a RooWorkspace.

However, for the sake of interoperability with other statistical frameworks, and also ease of manipulation, it may be useful to store statistical models in text form.

The RooJSONFactoryWSTool is a helper class to achieve exactly this, exporting to and importing from JSON.

In order to import a workspace from a JSON file, you can do

ws = ROOT.RooWorkspace("ws")
tool = ROOT.RooJSONFactoryWSTool(ws)
tool.importJSON("myjson.json")

Similarly, in order to export a workspace to a JSON file, you can do

tool = ROOT.RooJSONFactoryWSTool(ws)

tool.exportJSON("myjson.json")

Analogously, in C++, you can do

#include "RooFitHS3/RooJSONFactoryWSTool.h"
// ...
RooWorkspace ws("ws");
RooJSONFactoryWSTool tool(ws);
tool.importJSON("myjson.json");

and

#include "RooFitHS3/RooJSONFactoryWSTool.h"
// ...
RooJSONFactoryWSTool tool(ws);
tool.exportJSON("myjson.json");

For more details, consult the tutorial rf515_hfJSON.

The RooJSONFactoryWSTool only knows about a limited set of classes for import and export. If import or export of a class you're interested in fails, you might need to add your own importer or exporter. Please consult the relevant section in the RooFit Developer Documentation to learn how to do that (Implement JSON I/O for a RooFit class with RooFit HS3).

You can always get a list of all the available importers and exporters by calling the following functions:

ROOT.RooFit.JSONIO.printImporters()
ROOT.RooFit.JSONIO.printExporters()
ROOT.RooFit.JSONIO.printFactoryExpressions()
ROOT.RooFit.JSONIO.printExportKeys()

Alternatively, you can generate a LaTeX version of the available importers and exporters by calling

tool = ROOT.RooJSONFactoryWSTool(ws)

tool.writedoc("hs3.tex")

		const std::string &	name,
		RooArgSet const &	vars )

static

Read binned data from the JSONNode and create a RooDataHist object.

This function reads binned data from the given JSONNode and creates a RooDataHist object. The binned data is associated with the specified name and variables (RooArgSet) in the workspace.

Parameters

n	The JSONNode representing the binned data to be read.
name	The name to be associated with the created RooDataHist object.
vars	The RooArgSet representing the variables associated with the binned data.

Returns: std::unique_ptr<RooDataHist> A unique pointer to the created RooDataHist object.
