RooAbsCollection is an abstract container object that can hold multiple RooAbsArg objects.

Collections are ordered and can contain multiple objects of the same name, (but a derived implementation can enforce unique names). The storage of objects is implemented using the container denoted by RooAbsCollection::Storage_t.

PyROOT

Some member functions of RooAbsCollection that take a RooCmdArg as argument also support keyword arguments. So far, this applies to RooAbsCollection::printLatex. For example, the following code is equivalent in PyROOT:

# Directly passing a RooCmdArg:
params.printLatex(ROOT.RooFit.Sibling(initParams), ROOT.RooFit.Columns(2))
 
# With keyword arguments:
params.printLatex(Sibling=initParams, Columns =2)

Member Function Documentation

◆ add() [1/3]

Bool_t RooAbsCollection::add	(	const RooAbsArg &	var,
		Bool_t	silent = `kFALSE`
	)

virtual

Add the specified argument to list.

Returns kTRUE if successful, or else kFALSE 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 RooListProxy, RooSetProxy, RooListProxy, and RooSetProxy.

Definition at line 521 of file RooAbsCollection.cxx.

◆ add() [2/3]

bool RooAbsCollection::add	(	const RooAbsCollection &	list,
		bool	silent = `kFALSE`
	)

inline

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

Definition at line 134 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>>

		Iterator_t	endIt,
		bool	silent = `false`
	)

Definition at line 123 of file RooAbsCollection.h.

◆ addClone() [1/2]

RooAbsCollection::addClone	(	const RooAbsArg &	var,
		Bool_t	silent = `kFALSE`
	)

virtual

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.

PyROOT

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

Reimplemented in RooSetProxy, and RooSetProxy.

Definition at line 494 of file RooAbsCollection.cxx.

◆ addClone() [2/2]

void RooAbsCollection::addClone	(	const RooAbsCollection &	list,
		Bool_t	silent = `kFALSE`
	)

virtual

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

Reimplemented in RooSetProxy.

Definition at line 607 of file RooAbsCollection.cxx.

◆ addOwned() [1/4]

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

virtual

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:

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

Reimplemented in RooListProxy, and RooSetProxy.

Definition at line 551 of file RooAbsCollection.cxx.

◆ addOwned() [2/4]

RooAbsCollection::addOwned	(	RooAbsArg &	var,
		Bool_t	silent = `kFALSE`
	)

virtual

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).

PyROOT

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

Reimplemented in RooListProxy, RooSetProxy, RooListProxy, and RooSetProxy.

Definition at line 447 of file RooAbsCollection.cxx.

◆ addOwned() [3/4]

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

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 579 of file RooAbsCollection.cxx.

◆ addOwned() [4/4]

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

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).

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* 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_t 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()) );

Format

static char * Format(const char *format, va_list ap)
