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.

Member Function Documentation

◆ add() [1/2]

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 RooArgSet, RooListProxy, and RooSetProxy.

Definition at line 434 of file RooAbsCollection.cxx.

◆ add() [2/2]

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

virtual

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

Reimplemented in RooArgSet, RooListProxy, and RooSetProxy.

Definition at line 456 of file RooAbsCollection.cxx.

◆ addClone() [1/2]

RooAbsArg * 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.

Reimplemented in RooArgSet, and RooSetProxy.

Definition at line 408 of file RooAbsCollection.cxx.

◆ addClone() [2/2]

void RooAbsCollection::addClone	(	const RooAbsCollection &	list,

◆ addOwned() [1/2]

Bool_t RooAbsCollection::addOwned	(	const RooAbsCollection &	list,

	)

virtual

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

Reimplemented in RooArgSet, RooListProxy, and RooSetProxy.

Definition at line 474 of file RooAbsCollection.cxx.

◆ addOwned() [2/2]

Bool_t RooAbsCollection::addOwned	(	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. 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).

Reimplemented in RooArgSet, RooListProxy, and RooSetProxy.

Definition at line 382 of file RooAbsCollection.cxx.

Bool_t RooAbsCollection::addServerClonesToList ( const RooAbsArg & var )

Definition at line 1184 of file RooAbsCollection.cxx.

◆ assignFast()

void RooAbsCollection::assignFast	(	const RooAbsCollection &	other,
		Bool_t	setValDirty = `kTRUE`

◆ assignValueOnly()

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

◆ clone()

virtual TObject * RooAbsCollection::clone ( const char * newname ) const

pure virtual

Implemented in RooArgList, and RooArgSet.

◆ Clone()

virtual TObject * RooAbsCollection::Clone ( const char * newname = 0 ) const

inlinevirtual

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.

Output content of collection as LaTex table.

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_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)

Format a string in a circular formatting buffer (using a printf style format descriptor).
