Constructor from a generic function object
set cdf distribution using a generic function interface
evaluate the cumulative distribution otherwise evaluate from the sum of the probabilities
Clone (required by base class)
{ return new TUnuranDiscrDist(*this); }
Set the distribution domain, by default the domain is [0,INT_MAX]
If xmin >= xmax a domain is removed
check if distribution has domain and return in case its domain
flag to control if distribution provides the total area of the probability function
{ return fHasSum; }
retrieve a reference to the vector of the probabilities : Prob(i)
If the distribution is defined from a function (i.e. for distribution with undefined domain)
the vector is empty.
{ return fPVec; }
