RooArgSetclass description - source file - inheritance tree (.pdf) class RooArgSet : public RooAbsCollection

Data MembersClass DescriptionRooArgSet 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 using an iterator returned by createIterator(). 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. RooArgSet() : RooAbsCollection() Default constructor RooArgSet(const RooArgList& list) : RooAbsCollection(list.GetName()) Constructor from a RooArgList. If the list contains multiple objects with the same name, only the first is store in the set. Warning messages will be printed for dropped items. RooArgSet(const char *name) : RooAbsCollection(name) Empty set constructor RooArgSet(const RooAbsArg& var1, const char *name) : RooAbsCollection(name) Constructor for set containing 1 initial object RooArgSet(const RooAbsArg& var1, const RooAbsArg& var2, const char *name) : RooAbsCollection(name) Constructor for set containing 2 initial objects RooArgSet(const RooAbsArg& var1, const RooAbsArg& var2, const RooAbsArg& var3, const char *name) : RooAbsCollection(name) Constructor for set containing 3 initial objects RooArgSet(const RooAbsArg& var1, const RooAbsArg& var2, const RooAbsArg& var3, const RooAbsArg& var4, const char *name) : RooAbsCollection(name) Constructor for set containing 4 initial objects RooArgSet(const RooAbsArg& var1, const RooAbsArg& var2, const RooAbsArg& var3, const RooAbsArg& var4, const RooAbsArg& var5, const char *name) : RooAbsCollection(name) Constructor for set containing 5 initial objects RooArgSet(const RooAbsArg& var1, const RooAbsArg& var2, const RooAbsArg& var3, const RooAbsArg& var4, const RooAbsArg& var5, const RooAbsArg& var6, const char *name) : RooAbsCollection(name) Constructor for set containing 6 initial objects RooArgSet(const RooAbsArg& var1, const RooAbsArg& var2, const RooAbsArg& var3, const RooAbsArg& var4, const RooAbsArg& var5, const RooAbsArg& var6, const RooAbsArg& var7, const char *name) : RooAbsCollection(name) Constructor for set containing 7 initial objects RooArgSet(const RooAbsArg& var1, const RooAbsArg& var2, const RooAbsArg& var3, const RooAbsArg& var4, const RooAbsArg& var5, const RooAbsArg& var6, const RooAbsArg& var7, const RooAbsArg& var8, const char *name) : RooAbsCollection(name) Constructor for set containing 8 initial objects RooArgSet(const RooAbsArg& var1, const RooAbsArg& var2, const RooAbsArg& var3, const RooAbsArg& var4, const RooAbsArg& var5, const RooAbsArg& var6, const RooAbsArg& var7, const RooAbsArg& var8, const RooAbsArg& var9, const char *name) : RooAbsCollection(name) Constructor for set containing 9 initial objects RooArgSet(const TCollection& tcoll, const char* name) : RooAbsCollection(name) Constructor from a root TCollection. Elements in the collection that do not inherit from RooAbsArg will be skipped. A warning message will be printed for every skipped item. RooArgSet(const RooArgSet& other, const char *name) : RooAbsCollection(other,name) Copy constructor. Note that a copy of a set is always non-owning, even the source set is owning. To create an owning copy of a set (owning or not), use the snaphot() method. ~RooArgSet() Destructor Bool_t add(const RooAbsArg& var, Bool_t silent) Add element to non-owning set. The operation will fail if a similarly named object already exists in the set, or the set is specified to own its elements. Eventual error messages can be suppressed with the silent flag Bool_t addOwned(RooAbsArg& var, Bool_t silent) Add element to an owning set. The operation will fail if a similarly named object already exists in the set, or the set is not specified to own its elements. Eventual error messages can be suppressed with the silent flag RooAbsArg* addClone(const RooAbsArg& var, Bool_t silent) Add clone of specified element to an owning set. If sucessful, the set will own the clone, not the original. The operation will fail if a similarly named object already exists in the set, or the set is not specified to own its elements. Eventual error messages can be suppressed with the silent flag Bool_t checkForDup(const RooAbsArg& var, Bool_t silent) const Check if element with var's name is already in set Double_t getRealValue(const char* name, Double_t defVal, Bool_t verbose) const Bool_t setRealValue(const char* name, Double_t newVal, Bool_t verbose) const char* getCatLabel(const char* name, const char* defVal, Bool_t verbose) const Bool_t setCatLabel(const char* name, const char* newVal, Bool_t verbose) Int_t getCatIndex(const char* name, Int_t defVal, Bool_t verbose) const Bool_t setCatIndex(const char* name, Int_t newVal, Bool_t verbose) const char* getStringValue(const char* name, const char* defVal, Bool_t verbose) const Bool_t setStringValue(const char* name, const char* newVal, Bool_t verbose) void writeToFile(const char* fileName) Write contents of the argset to specified file. See writeToStream() for details Bool_t readFromFile(const char* fileName, const char* flagReadAtt, const char* section, Bool_t verbose) Read contents of the argset from specified file. See readFromStream() for details void writeToStream(ostream& os, Bool_t compact, const char* /*section*/) Write the contents of the argset in ASCII form to given stream. 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. Bool_t readFromStream(istream& is, Bool_t compact, const char* flagReadAtt, const char* section, Bool_t verbose) Read the contents of the argset in ASCII form from given stream.
The stream is read to end-of-file and each line is assumed to be
of the form
<argName> = <argValue>
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>)
....
> else
....
> endif
All expressions are evaluated by RooFormula, and may involve any of
the sets variables.
> echo <Message>
Print console message while reading from stream
> abort
Force termination of read sequence with error status
The value of each argument is read by the arguments readFromStream
function.
