RooArgList Class Reference

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

The container has list semantics which means that:

• Contained objects are ordered, The iterator follows the object insertion order.
• Objects can be retrieved by name and index
• Multiple objects with the same name are allowed

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.

(

Int_t

idx

)

const

Array operator.

Element in slot 'idx' must already exist, 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!

readFromStream()

Bool_t RooArgList::readFromStream ( std::istream &  is, Bool_t  compact, Bool_t  verbose = kFALSE  )

virtual

Read the contents of the argset in ASCII form from given stream.

A single line is read, and all elements are assumed to be separated by white space. The value of each argument is read by the arguments readFromStream function.

Definition at line 323 of file RooArgList.cxx.

writeToStream()

void RooArgList::writeToStream ( std::ostream &  os, Bool_t  compact  )

virtual

Write the contents of the argset in ASCII form to given stream.

All elements will be printed on a single line separated by a single white space. The contents of each element is written by the arguments' writeToStream() function
