TUnuran(TRandom* r = 0, unsigned int log = 0)

 constructor implementation with a ROOT random generator
 if no generator is given the ROOT default is used

bool Init(const TUnuranContDist & distr, const std::string & method)

 initialization with a distribution and and generator
 the distribution object is copied in and managed by this class
 use auto_ptr to manage previously existing distribution objects

bool Init(const TUnuranMultiContDist & distr, const std::string & method)

  initialization with a distribution and method
 the distribution object is copied in and managed by this class
 use auto_ptr to manage previously existing distribution objects

bool Init(const TUnuranDiscrDist & distr, const std::string & method )

   initialization with a distribution and and generator
 the distribution object is copied in and managed by this class
 use auto_ptr to manage previously existing distribution objects

bool Init(const TUnuranEmpDist & distr, const std::string & method )

   initialization with a distribution and and generator
 the distribution object is copied in and managed by this class
 use auto_ptr to manage previously existing distribution objects

bool SetContDistribution(const TUnuranContDist& dist)

 internal method to set in unuran the function pointer for a continous univariate distribution

bool SetMultiDistribution(const TUnuranMultiContDist& dist)

 internal method to set in unuran the function pointer for a multivariate distribution

bool SetDiscreteDistribution(const TUnuranDiscrDist& dist)

 internal method to set in unuran the function pointer for a discrete univariate distribution

bool ReInitDiscrDist(unsigned int npar, double* params)

 re-initialization of UNURAN without freeing and creating a new fGen object
 works only for pre-defined distribution by changing their parameters

bool SetLogStream()

      set stream for log and error (not yet implemented)

{ return false;}

const std::string & MethodName()

      used Unuran method

{ return fMethod; }
