RooWorkspace Class Reference

The RooWorkspace is a 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
static constexpr double 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)

Creating variables
x[-10,10] Create variable x with given range and put it in workspace
x[3,-10,10] Create variable x with given range and initial value and put it in workspace
x[3] Create variable x with given constant value

The functionality of high-level object creation tools like RooSimWSTool, RooCustomizer and RooClassFactory is also interfaced through meta-types in the factory.

Interface to RooSimWSTool
SIMCLONE::name( modelPdf, $ParamSplit(...), $ParamSplitConstrained(...), $Restrict(...) ]

Interface to RooClassFactory
CEXPR::name(<expr>,var,...] Create a custom compiled pdf that evaluates the given expression
cexpr::name(<expr>,var,...]

Create a custom compiled function that evaluates the given expression

$MetaType(...) Meta argument that does not result in construction of an object but is used logically organize input arguments in certain operator pdf constructions. The defined meta arguments are context dependent. The only meta argument that is defined globally is $Alias(typeName,aliasName) to define aliases for type names. For the definition of meta arguments in operator pdfs see the definitions below.

)

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.

◆ import() [2/6]

RooWorkspace::import ( const RooAbsArg arg,

const RooCmdArg arg2 = RooCmdArg(),
const RooCmdArg arg3 = RooCmdArg(),
const RooCmdArg arg4 = RooCmdArg(),

const RooCmdArg arg6 = RooCmdArg(),
const RooCmdArg arg7 = RooCmdArg(),
const RooCmdArg arg8 = RooCmdArg(),
const RooCmdArg arg9 = RooCmdArg() 
)

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.
