class RooAddModel: public RooResolutionModel

 Generic constructor from list of PDFs and list of coefficients.
 Each pdf list element (i) is paired with coefficient list element (i).
 The number of coefficients must be either equal to the number of PDFs,
 in which case extended MLL fitting is enabled, or be one less.

 All PDFs must inherit from RooAbsPdf. All coefficients must inherit from RooAbsReal

 Copy constructor

 Destructor

 Instantiate a clone of this resolution model representing a convolution with given
 basis function. The owners object name is incorporated in the clones name
 to avoid multiple convolution objects with the same name in complex PDF structures.

 RooAddModel will clone all the component models to create a composite convolution object

 Return code for basis function representing by 'name' string.
 The basis code of the first component model will be returned,
 if the basis is supported by all components. Otherwise 0
 is returned

 Calculate the current value

 Reset error counter to given value, limiting the number
 of future error messages for this pdf to 'resetValue'

 Check if PDF is valid for given normalization set.
 Coeffient and PDF must be non-overlapping, but pdf-coefficient
 pairs may overlap each other

 Check if this configuration was created before

 Return analytical integral defined by given scenario code

 Return the number of expected events, which is either the sum of all coefficients
 or the sum of the components extended terms

 Ignore automatic adjustments if an explicit reference normalization has been selected

 Ignore automatic adjustments if an explicit reference range has been selected
