RooArgSet Class Reference

RooArgSet is a container object that can hold multiple RooAbsArg objects.

The container has set semantics which means that:

  • Every object it contains must have a unique name returned by GetName().
  • Contained objects are not ordered, although the set can be traversed just like standard library containers such as std::vector (in fact, the RooArgSet uses a std::vector<RooAbsArg *> under the hood). The iterator does not necessarily follow the object insertion order.
  • Objects can be retrieved by name only, and not by index.

Ownership of contents

Unowned objects are inserted with the add() method. Owned objects are added with addOwned() or addClone(). A RooArgSet either owns all of it contents, or none, which is determined by the first add call. Once an ownership status is selected, inappropriate add calls will return error status. Clearing the list via removeAll() resets the ownership status. Arguments supplied in the constructor are always added as unowned elements.

Uniquely identifying RooArgSet objects

Warning
Before v6.28, it was ensured that no RooArgSet objects on the heap were located at an address that had already been used for a RooArgSet before. With v6.28, this is not guaranteed anymore. Hence, if your code uses pointer comparisons to uniquely identify RooArgSet instances, please consider using the new RooArgSet::uniqueId().

kOnlyPrepStep 

Used to request that the class specific implementation of TObject::Write just prepare the objects to be ready to be written but do not actually write them into the TBuffer.

This is just for example by TBufferMerger to request that the TTree inside the file calls TTree::FlushBaskets (outside of the merging lock) and TBufferMerger will later ask for the write (inside the merging lock).

◆ RooArgSet() [2/13]

template<typename... Args_t>
RooArgSet::RooArgSet ( const RooAbsArg & arg,
Args_t &&... moreArgsOrName )
inline

Construct a (non-owning) RooArgSet from one or more RooFit objects.

The set will not own its contents.

Template Parameters
TsParameter pack of objects that derive from RooAbsArg or RooFit collections; or a name.
Parameters
argA RooFit object. Note that you can also pass a double as first argument when constructing a RooArgSet, and another templated constructor will be used where a RooConstVar is implicitly created from the double value.
moreArgsOrNameArbitrary number of
  • Further RooFit objects that derive from RooAbsArg
  • RooFit collections of such objects
  • doubles from which a RooConstVar is implicitly created via RooFit::RooConst.
  • A name for the set. Given multiple names, the last-given name prevails.

◆ RooArgSet() [6/13]

RooArgSet::RooArgSet ( std::vector< RooAbsArgPtrOrDouble > const & vec)
inline

Construct a non-owning RooArgSet from a vector of RooAbsArg pointers.

This constructor is mainly intended for pyROOT. With cppyy, a Python list or tuple can be implicitly converted to an std::vector, and by enabling implicit construction of a RooArgSet from a std::vector, we indirectly enable implicit conversion from a Python list/tuple to RooArgSets.

Parameters
vecA vector with pointers to the arguments or doubles for RooFit::RooConst().

Member Function Documentation

◆ AbstractMethod()

void TObject::AbstractMethod ( const char * method) const
inherited

Call this function within a function that you don't want to define as purely virtual, in order not to force all users deriving from that class to implement that maybe (on their side) unused function; but at the same time, emit a run-time warning if they try to call it, telling that it is not implemented in the derived class: action must thus be taken on the user side to override it.

In other word, this method acts as a "runtime purely virtual" warning instead of a "compiler purely virtual" error.

Warning
This interface is a legacy function that is no longer recommended to be used by new development code.
Note
The name "AbstractMethod" does not imply that it's an abstract method in the strict C++ sense.

Definition at line 1149 of file TObject.cxx.

◆ add() [1/3]

bool RooAbsCollection::add ( const RooAbsArg & var,
bool silent = false )
virtualinherited

Add the specified argument to list.

Returns true if successful, or else false if a variable of the same name is already in the list or the list owns its variables (in this case, try addClone() or addOwned() instead).

Reimplemented in RooCollectionProxy< RooArgList >, and RooCollectionProxy< RooArgSet >.

Definition at line 442 of file RooAbsCollection.cxx.

◆ add() [2/3]

bool RooAbsCollection::add ( const RooAbsCollection & list,
bool silent = false )
inlineinherited

Add a collection of arguments to this collection by calling add() for each element in the source collection.

Definition at line 151 of file RooAbsCollection.h.

◆ add() [3/3]

template<typename Iterator_t, typename value_type = typename std::remove_pointer<typename std::iterator_traits<Iterator_t>::value_type>, typename = std::enable_if<std::is_convertible<const value_type*, const RooAbsArg*>::value>>
bool RooAbsCollection::add ( Iterator_t beginIt,
Iterator_t endIt,
bool silent = false )
inlineinherited

Definition at line 140 of file RooAbsCollection.h.

◆ addClone() [1/2]

RooAbsArg * RooAbsCollection::addClone ( const RooAbsArg & var,
bool silent = false )
virtualinherited

Add a clone of the specified argument to list.

Returns a pointer to the clone if successful, or else zero if a variable of the same name is already in the list or the list does not own its variables (in this case, try add() instead.) Calling addClone() on an empty list forces it to take ownership of all its subsequent variables.

Reimplemented in RooCollectionProxy< RooArgList >, and RooCollectionProxy< RooArgSet >.

Definition at line 415 of file RooAbsCollection.cxx.

◆ addClone() [2/2]

void RooAbsCollection::addClone ( const RooAbsCollection & list,
bool silent = false )
virtualinherited

Add a collection of arguments to this collection by calling addOwned() for each element in the source collection.

Reimplemented in RooCollectionProxy< RooArgList >, and RooCollectionProxy< RooArgSet >.

Definition at line 530 of file RooAbsCollection.cxx.

◆ addOwned() [1/4]

bool RooAbsCollection::addOwned ( const RooAbsCollection & list,
bool silent = false )
virtualinherited

for each element in the source collection.

The input list can't be an owning collection itself, otherwise the arguments would be owned by two collections.

If you want to transfer arguments from one owning collection to another, you have two options:

  1. std::move the input collection and use RooAbsCollection::addOwned(RooAbsCollection&&, bool) (preferred)
  2. release the ownership of the input collection first, using RooAbsCollection::releaseOwnership()

Reimplemented in RooCollectionProxy< RooArgList >, and RooCollectionProxy< RooArgSet >.

Definition at line 472 of file RooAbsCollection.cxx.

◆ addOwned() [2/4]

bool RooAbsCollection::addOwned ( RooAbsArg & var,
bool silent = false )
virtualinherited

Add an argument and transfer the ownership to the collection.

Returns true if successful, or false if the argument could not be added to the collection (e.g. in the RooArgSet case when an argument with the same name is already in the list). This method can only be called on a list that is flagged as owning all of its contents, or else on an empty list (which will force the list into that mode).

If the argument you want to add is owned by a std::unique_ptr, you should prefer RooAbsCollection::addOwned(std::unique_ptr<RooAbsArg>, bool).

Reimplemented in RooCollectionProxy< RooArgList >, and RooCollectionProxy< RooArgSet >.

Definition at line 366 of file RooAbsCollection.cxx.

◆ addOwned() [3/4]

bool RooAbsCollection::addOwned ( RooAbsCollection && list,
bool silent = false )
inherited

Add a collection of arguments to this collection by calling addOwned() for each element in the source collection.

Unlike RooAbsCollection::addOwned(const RooAbsCollection&, bool), this function also accepts owning source collections because their content will be moved out.

Definition at line 500 of file RooAbsCollection.cxx.

◆ addOwned() [4/4]

bool RooAbsCollection::addOwned ( std::unique_ptr< RooAbsArg > var,
bool silent = false )
inherited

Add an argument and transfer the ownership to the collection from a std::unique_ptr.

Always returns true. If the argument can not be added to the collection (e.g. in the RooArgSet case when an argument with the same name is already in the list), a std::runtime_exception will be thrown, as nobody is owning the argument anymore. This method can only be called on a list that is flagged as owning all of its contents, or else on an empty list (which will force the list into that mode).

If you want to pass an argument that is not owned by a std::unique_ptr, you can use RooAbsCollection::addOwned(RooAbsArg&, bool).

Definition at line 395 of file RooAbsCollection.cxx.

◆ AddToTObjectTable()

void TObject::AddToTObjectTable ( TObject * op)
staticprivateinherited

Private helper function which will dispatch to TObjectTable::AddObj.

Included here to avoid circular dependency between header files.

Definition at line 195 of file TObject.cxx.

◆ addTyped()

template<class Arg_t>
bool RooAbsCollection::addTyped ( const RooAbsCollection & list,
bool silent = false )
inlineinherited

Adds elements of a given RooAbsCollection to the container if they match the specified type.

This function iterates through the elements of the provided RooAbsCollection and checks if each element matches the specified type. If any element doesn't match the type, it throws an exception.

Template Parameters
Arg_tThe type to match for elements in the collection. Must inherit from RooAbsArg.
Parameters
listThe RooAbsCollection containing elements to be added.
silentForwarded to the non-typed add function. If true, suppresses error messages when adding elements, e.g. when the collection is a RooArgSet and the element is already in the set.
Returns
Returns true if all elements could be added, else false.
Exceptions
std::invalid_argumentif an element in the collection doesn't match the specified type.

◆ assign()

void RooAbsCollection::assign ( const RooAbsCollection & other) const
inherited

Sets the value, cache and constant attribute of any argument in our set that also appears in the other set.

Note that this function changes the values of the elements in this collection, but is still marked const as it does not change which elements this collection points to.

Definition at line 282 of file RooAbsCollection.cxx.

◆ assignFast()

void RooAbsCollection::assignFast ( const RooAbsCollection & other,
bool setValDirty = true ) const

Functional equivalent of assign() but assumes this and other collection have same layout.

Also no attributes are copied

Definition at line 330 of file RooAbsCollection.cxx.

◆ assignValueOnly()

RooAbsCollection & RooAbsCollection::assignValueOnly ( const RooAbsCollection & other,

◆ CheckedHash()

ULong_t TObject::CheckedHash ( )
inlineinherited

Check and record whether this class has a consistent Hash/RecursiveRemove setup (*) and then return the regular Hash value for this object.

The intent is for this routine to be called instead of directly calling the function Hash during "insert" operations. See TObject::HasInconsistenTObjectHash();

(*) The setup is consistent when all classes in the class hierarchy that overload TObject::Hash do call ROOT::CallRecursiveRemoveIfNeeded in their destructor. i.e. it is safe to call the Hash virtual function during the RecursiveRemove operation.

Make a clone of an object using the Streamer facility.

If the object derives from TNamed, this function is called by TNamed::Clone. TNamed::Clone uses the optional argument to set a new name to the newly created object.

If the object class has a DirectoryAutoAdd function, it will be called at the end of the function with the parameter gDirectory. This usually means that the object will be appended to the current ROOT directory.

Definition at line 516 of file TObject.cxx.

◆ Hash()

ULong_t TObject::Hash ( ) const
virtualinherited

Return hash value for this object.

Note: If this routine is overloaded in a derived class, this derived class should also add

void CallRecursiveRemoveIfNeeded(TObject &obj)
call RecursiveRemove for obj if gROOT is valid and obj.TestBit(kMustCleanup) is true.
Definition TROOT.h:406

Otherwise, when RecursiveRemove is called (by ~TObject or example) for this type of object, the transversal of THashList and THashTable containers will will have to be done without call Hash (and hence be linear rather than logarithmic complexity). You will also see warnings like

Error in <ROOT::Internal::TCheckHashRecursiveRemoveConsistency::CheckRecursiveRemove>: The class SomeName overrides
TObject::Hash but does not call TROOT::RecursiveRemove in its destructor.
virtual void Error(const char *method, const char *msgfmt,...) const

◆ HasInconsistentHash()

Bool_t TObject::HasInconsistentHash ( ) const
inlineinherited

Return true is the type of this object is known to have an inconsistent setup for Hash and RecursiveRemove (i.e.

missing call to RecursiveRemove in destructor).

Note: Since the consistency is only tested for during inserts, this routine will return true for object that have never been inserted whether or not they have a consistent setup. This has no negative side-effect as searching for the object with the right or wrong Hash will always yield a not-found answer (Since anyway no hash can be guaranteed unique, there is always a check)

Definition at line 366 of file TObject.h.

◆ IsDestructed()

Bool_t TObject::IsDestructed ( ) const
inlineinherited

IsDestructed.

Note
This function must be non-virtual as it can be used on destructed (but not yet modified) memory. This is used for example in TClonesArray to record the element that have been destructed but not deleted and thus are ready for re-use (by operator new with placement).
Returns
true if this object's destructor has been run.

Definition at line 186 of file TObject.h.

◆ IsEqual()

Bool_t TObject::IsEqual ( const TObject * obj) const

void TObject::Paint ( Option_t * option = "")
virtualinherited

This method must be overridden if a class wants to paint itself.

Output content of collection as LaTex table.

PyROOT

The RooAbsCollection::printLatex() function is pythonized with the command argument pythonization. The keywords must correspond to the CmdArgs of the function.

By default a table with two columns is created: the left column contains the name of each variable, the right column the value.

The following optional named arguments can be used to modify the default behavior

Argument Effect
Columns(Int_t ncol) Fold table into multiple columns, i.e. ncol=3 will result in 3 x 2 = 6 total columns
Sibling(const RooAbsCollection& other) Define sibling list. The sibling list is assumed to have objects with the same name in the same order. If this is not the case warnings will be printed. If a single sibling list is specified, 3 columns will be output: the (common) name, the value of this list and the value in the sibling list. Multiple sibling lists can be specified by repeating the Sibling() command.
Format(const char* str) Classic format string, provided for backward compatibility
Format() Formatting arguments.
const char* what Controls what is shown. "N" adds name, "E" adds error, "A" shows asymmetric error, "U" shows unit, "H" hides the value
FixedPrecision(int n) Controls precision, set fixed number of digits
AutoPrecision(int n) Controls precision. Number of shown digits is calculated from error and n specified additional digits (1 is sensible default)
VerbatimName(bool flag) Put variable name in a \verb+ + clause.
OutputFile(const char* fname)

Send output to file with given name rather than standard output

Example use:

list.printLatex(Columns(2), Format("NEU",AutoPrecision(1),VerbatimName()) );
static char * Format(const char *format, va_list ap)
Format a string in a circular formatting buffer (using a printf style format descriptor).

Lines starting with argNames not matching any element in the list will be ignored with a warning message. In addition limited C++ style preprocessing and flow control is provided. The following constructions are recognized:

include "include.file"

Include given file, recursive inclusion OK

if (<boolean_expression>)
<name> = <value>
....
else if (<boolean_expression>)

virtualinherited

Save this object in the file specified by filename.

  • if "filename" contains ".root" the object is saved in filename as root binary file.
  • if "filename" contains ".xml" the object is saved in filename as a xml ascii file.
  • if "filename" contains ".cc" the object is saved in filename as C code independent from ROOT. The code is generated via SavePrimitive(). Specific code should be implemented in each object to handle this option. Like in TF1::SavePrimitive().
  • otherwise the object is written to filename as a CINT/C++ script. The C++ code to rebuild this object is generated via SavePrimitive(). The "option" parameter is passed to SavePrimitive. By default it is an empty string. It can be used to specify the Draw option in the code generated by SavePrimitive.

    The function is available via the object context menu.

◆ Write() [2/2]

Int_t TObject::Write ( const char * name = nullptr,
Int_t option = 0,
Int_t bufsize = 0 ) const
virtualinherited

Write this object to the current directory.

The data structure corresponding to this object is serialized. The corresponding buffer is written to the current directory with an associated key with name "name".

Writing an object to a file involves the following steps:

  • Creation of a support TKey object in the current directory. The TKey object creates a TBuffer object.
  • The TBuffer object is filled via the class::Streamer function.
  • If the file is compressed (default) a second buffer is created to hold the compressed buffer.
  • Reservation of the corresponding space in the file by looking in the TFree list of free blocks of the file.
  • The buffer is written to the file.

Bufsize can be given to force a given buffer size to write this object. By default, the buffersize will be taken from the average buffer size of all objects written to the current file so far.

If a name is specified, it will be the name of the key. If name is not given, the name of the key will be the name as returned by GetName().

The option can be a combination of: kSingleKey, kOverwrite or kWriteDelete Using the kOverwrite option a previous key with the same name is overwritten. The previous key is deleted before writing the new object. Using the kWriteDelete option a previous key with the same name is deleted only after the new object has been written. This option is safer than kOverwrite but it is slower. NOTE: Neither kOverwrite nor kWriteDelete reduces the size of a TFile– the space is simply freed up to be overwritten; in the case of a TTree, it is more complicated. If one opens a TTree, appends some entries, then writes it out, the behaviour is effectively the same. If, however, one creates a new TTree and writes it out in this way, only the metadata is replaced, effectively making the old data invisible without deleting it. TTree::Delete() can be used to mark all disk space occupied by a TTree as free before overwriting its metadata this way. The kSingleKey option is only used by TCollection::Write() to write a container with a single key instead of each object in the container with its own key.

An object is read from the file into memory via TKey::Read() or via TObject::Read().

The function returns the total number of bytes written to the file. It returns 0 if the object cannot be written.

Reimplemented in TBuffer, TCollection, TDirectory, TDirectoryFile, TFile, TMap, TParallelMergingFile, TSQLFile, TTree, and TXMLFile.

A line is written for each element contained in the form <argName> = <argValue>

The <argValue> part of each element is written by the arguments' writeToStream() function.

Parameters
osThe stream to write to.
compactWrite only the bare values, separated by ' '.
Note
In compact mode, the stream cannot be read back into a RooArgSet, but only into a RooArgList, because the variable names are lost.
Parameters
sectionIf non-null, add a section header like [<section>].
