Function documentation

BaseIntegratorOptions & operator=(const ROOT::Math::IntegratorOneDimOptions& rhs)

 assignment operators

std::string Integrator() const

 name of 1D integrator

IntegratorOneDimOptions(IOptions * extraOpts = 0)

 constructor using the default options
 can pass a pointer to extra options (N.B. pointer will be managed by the class)

virtual ~IntegratorOneDimOptions()

{}

IntegratorOneDimOptions(const IntegratorOneDimOptions & rhs)

 copy constructor

{}

void SetNPoints(unsigned int n)

 specific method for one-dim
 set number of points rule
 values of 1,2,3,4,5,6 corresponds to 15,21,31,41,51,61 and they are used in GSL adaptive
 values > 6 corresponds to the actual points and they are used by teh GaussLegendre integrator

{ fNCalls = n; }

unsigned int NPoints() const

 maximum number of function calls

{ return fNCalls; }

IntegrationOneDim::Type IntegratorType() const

 type of the integrator (return the enumeration type)

{ return (IntegrationOneDim::Type) fIntegType; }

void SetIntegrator(const char* name)

 set 1D integrator name

void Print(ostream& os = std::cout) const

 print all the options

void SetDefaultIntegrator(const char* name)

 static methods for setting and retrieving the default options

void SetDefaultAbsTolerance(double tol)

void SetDefaultRelTolerance(double tol)

void SetDefaultWKSize(unsigned int size)

void SetDefaultNPoints(unsigned int n)

std::string DefaultIntegrator()

IntegrationOneDim::Type DefaultIntegratorType()

double DefaultAbsTolerance()

double DefaultRelTolerance()

unsigned int DefaultWKSize()

unsigned int DefaultNPoints()

ROOT::Math::IOptions & Default(const char* name)

 retrieve specific options - if not existing create a IOptions

ROOT::Math::IOptions * FindDefault(const char* name)

 find specific options - return 0 if not existing

void PrintDefault(const char* name = 0, ostream& os = std::cout)

 print only the specified default options
