class RooArgSet: public RooAbsCollection

 Clear memoery pool on exit to avoid reported memory leaks

 Overloaded new operator guarantees that all RooArgSets allocated with new
 have a unique address, a property that is exploited in several places
 in roofit to quickly index contents on normalization set pointers.
 The memory pool only allocates space for the class itself. The elements
 stored in the set are stored outside the pool.

 Memory is owned by pool, we need to do nothing to release it

 Default constructor

 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.

 Empty set constructor

 Constructor for set containing 1 initial object

 Constructor for set containing 2 initial objects

 Constructor for set containing 3 initial objects

 Constructor for set containing 4 initial objects

 Constructor for set containing 5 initial objects

 Constructor for set containing 6 initial objects

 Constructor for set containing 7 initial objects

 Constructor for set containing 8 initial objects

 Constructor for set containing 9 initial objects

 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.

 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.

 Destructor

 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

 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

 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

 Array operator. Named element must exist in set, otherwise
 code will abort.

 When used as lvalue in assignment operations, the element contained in
 the list will not be changed, only the value of the existing element!

 Check if element with var's name is already in set

 Get value of a RooAbsReal stored in set with given name. If none is found, value of defVal is returned.
 No error messages are printed unless the verbose flag is set

 Set value of a RooAbsRealLValye stored in set with given name to newVal
 No error messages are printed unless the verbose flag is set

 Get state name of a RooAbsCategory stored in set with given name. If none is found, value of defVal is returned.
 No error messages are printed unless the verbose flag is set

 Set state name of a RooAbsCategoryLValue stored in set with given name to newVal.
 No error messages are printed unless the verbose flag is set

 Get index value of a RooAbsCategory stored in set with given name. If none is found, value of defVal is returned.
 No error messages are printed unless the verbose flag is set

 Set index value of a RooAbsCategoryLValue stored in set with given name to newVal.
 No error messages are printed unless the verbose flag is set

 Get string value of a RooAbsString stored in set with given name. If none is found, value of defVal is returned.
 No error messages are printed unless the verbose flag is set

 Set string value of a RooStringVar stored in set with given name to newVal.
 No error messages are printed unless the verbose flag is set

 Write contents of the argset to specified file.
 See writeToStream() for details

 Read contents of the argset from specified file.
 See readFromStream() for details

 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.

 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.
