RandFlat

Class defining methods for shooting flat random numbers, double or integers. It provides also static methods to fill with double flat values arrays of specified size.

Default boundaries ]0,1[ for operator()().

Public Member Functions

Constructors

inline RandFlat ( HepRandomEngine& anEngine )

inline RandFlat ( HepRandomEngine& anEngine, HepDouble width )

inline RandFlat ( HepRandomEngine& anEngine, HepDouble a, HepDouble b )

inline RandFlat ( HepRandomEngine* anEngine )

inline RandFlat ( HepRandomEngine* anEngine, HepDouble width )

inline RandFlat ( HepRandomEngine* anEngine, HepDouble a, HepDouble b )

These constructors should be used to instantiate a RandFlat distribution object defining a local engine for it.
The static generator will be skeeped using the non-static methods defined below.
If the engine is passed by pointer then the corresponding engine object will be deleted by the RandFlat destructor.
If the engine is passed by reference then the corresponding engine object will not be deleted by the RandFlat destructor.

Destructor

virtual ~RandFlat()

()

HepDouble operator()()

HepDouble operator()( HepDouble width )

HepDouble operator()( HepDouble a, HepDouble b )

To get a flat random number using the operator().
