RooWorkspace Class Reference

Persistable container for RooFit projects.

A workspace can contain and own variables, p.d.f.s, functions and datasets. All objects that live in the workspace are owned by the workspace. The import() method enforces consistency of objects upon insertion into the workspace (e.g. no duplicate object with the same name are allowed) and makes sure all objects in the workspace are connected to each other. Easy accessor methods like pdf(), var() and data() allow to refer to the contents of the workspace by object name. The entire RooWorkspace can be saved into a ROOT TFile and organises the consistent streaming of its contents without duplication. If a RooWorkspace contains custom classes, i.e. classes not in the ROOT distribution, portability of workspaces can be enhanced by storing the source code of those classes in the workspace as well. This process is also organized by the workspace through the importClassCode() method.

Seemingly random crashes when reading large workspaces

When reading or loading workspaces with deeply nested PDFs, one can encounter ouf-of-memory errors if the stack size is too small. This manifests in crashes at seemingly random locations, or in the process silently ending. Unfortunately, ROOT neither recover from this situation, nor warn or give useful instructions. When suspecting to have run out of stack memory, check

ulimit -s

and try reading again.

PyROOT

The RooWorkspace::import function can't be used in PyROOT because import is a reserved python keyword. For this reason, an alternative with a capitalized name is provided:

workspace.Import(x)

		const RooCmdArg &	arg6 = {},
		const RooCmdArg &	arg7 = {},
		const RooCmdArg &	arg8 = {},
		const RooCmdArg &	arg9 = {}
	)

Import a RooAbsArg or RooAbsData set from a workspace in a file.

Filespec should be constructed as "filename:wspacename:objectname" The arguments will be passed to the relevant import() or import(RooAbsData&, ...) import calls

Note

From python, use Import(), since import is a reserved keyword.

PyROOT

Support the C++ import() as Import() in python

Definition at line 271 of file RooWorkspace.cxx.

import() [2/6]

RooWorkspace::import	(	const RooAbsArg &	arg,
		const RooCmdArg &	arg1 = {},
		const RooCmdArg &	arg2 = {},
		const RooCmdArg &	arg3 = {},
		const RooCmdArg &	arg4 = {},
		const RooCmdArg &	arg5 = {},
		const RooCmdArg &	arg6 = {},
		const RooCmdArg &	arg7 = {},
		const RooCmdArg &	arg8 = {},
		const RooCmdArg &	arg9 = {}
	)

Import a RooAbsArg object, e.g.

function, p.d.f or variable into the workspace. This import function clones the input argument and will own the clone. If a composite object is offered for import, e.g. a p.d.f with parameters and observables, the complete tree of objects is imported. If any of the variables of a composite object (parameters/observables) are already in the workspace the imported p.d.f. is connected to the already existing variables. If any of the function objects (p.d.f, formulas) to be imported already exists in the workspace an error message is printed and the import of the entire tree of objects is cancelled. Several optional arguments can be provided to modify the import procedure.

Accepted arguments
RenameConflictNodes(const char* suffix)	Add suffix to branch node name if name conflicts with existing node in workspace
RenameAllNodes(const char* suffix)	Add suffix to all branch node names including top level node.
RenameAllVariables(const char* suffix)	Add suffix to all variables of objects being imported.
RenameAllVariablesExcept(const char* suffix, const char* exceptionList)	Add suffix to all variables names, except ones listed
RenameVariable(const char* inputName, const char* outputName)	Rename a single variable as specified upon import.
RecycleConflictNodes()	If any of the function objects to be imported already exist in the name space, connect the imported expression to the already existing nodes. Attention Use with care! If function definitions do not match, this alters the definition of your function upon import
Silence()	Do not issue any info message

The RenameConflictNodes, RenameNodes and RecycleConflictNodes arguments are mutually exclusive. The RenameVariable argument can be repeated as often as necessary to rename multiple variables. Alternatively, a single RenameVariable argument can be given with two comma separated lists.

Note

From python, use Import(), since import is a reserved keyword.

PyROOT

The RooWorkspace constructor is pythonized with the command argument pythonization. The keywords must correspond to the CmdArgs of the constructor.

	)

Import a dataset (RooDataSet or RooDataHist) into the work space.

The workspace will contain a copy of the data. The dataset and its variables can be renamed upon insertion with the options below

Accepted arguments
Rename(const char* suffix)	Rename dataset upon insertion
RenameVariable(const char* inputName, const char* outputName)	Change names of observables in dataset upon insertion
Silence	Be quiet, except in case of errors Note From python, use Import(), since import is a reserved keyword.

Definition at line 726 of file RooWorkspace.cxx.

import() [5/6]

bool RooWorkspace::import	(	TObject const &	object,
		bool	replaceExisting = false
	)

Import a clone of a generic TObject into workspace generic object container.

The imported object will be stored under the given alias name rather than its own name. Imported object can be retrieved its alias name through the obj() method.
