class RooStats::LikelihoodInterval: public RooStats::ConfInterval

 default constructor

 construct the interval from a Profile Likelihood object, parameter of interest and optionally a snapshot of
 POI with their best fit values

 destructor

 check if given point is in the interval

 set the confidence level for the interval (e.g 0.682 for a 1-sigma interval)

 return confidence level

 return a cloned list of parameters of interest.  User manages the return object

 check if parameters are correct (i.e. they are the POI of this interval)

 return the lower bound of the interval on a given parameter

 return the upper bound of the interval on a given parameter

 find both lower and upper interval boundaries for a given parameter
 retun false if the bounds have not been found

         return the 2D-contour points for the given subset of parameters
         by default make the contour using 30 points. The User has to preallocate the x and y array which will return
         the set of x and y points defining the contour.
         The return value of the funciton specify the number of contour point found.
         In case of error a zero is returned

 return the profile log-likelihood ratio function

 return a pointer to a snapshot with best fit parameter of interest

 reset the cached limit values

 internal function to create the minimizer for finding the contours
