Function documentation

TArrayF()
 Default TArrayF ctor.
TArrayF(Int_t n)
 Create TArrayF object and set array size to n floats.
TArrayF(Int_t n, const Float_t* array)
 Create TArrayF object and initialize it with values of array.
TArrayF(const TArrayF &array)
 Copy constructor.
TArrayF & operator=(const TArrayF& rhs)
 TArrayF assignment operator.
~TArrayF()
 Delete TArrayF object.
void Adopt(Int_t n, Float_t* array)
 Adopt array arr into TArrayF, i.e. don't copy arr but use it directly
 in TArrayF. User may not delete arr, TArrayF dtor will do it.
void AddAt(Float_t c, Int_t i)
 Add float c at position i. Check for out of bounds.
void Set(Int_t n)
 Set size of this array to n floats.
 A new array is created, the old contents copied to the new array,
 then the old array is deleted.
 This function should not be called if the array was declared via Adopt.
void Set(Int_t n, const Float_t* array)
 Set size of this array to n floats and set the contents.
 This function should not be called if the array was declared via Adopt.
void Streamer(TBuffer& b)
 Stream a TArrayF object.
Float_t At(Int_t i) const
Float_t & operator[](Int_t i)
Float_t operator[](Int_t i)
void Copy(TArrayF& array) const
{array.Set(fN,fArray);}
const Float_t * GetArray()
{ return fArray; }
Float_t * GetArray()
{ return fArray; }
Stat_t GetSum()
{Stat_t sum=0; for (Int_t i=0;i<fN;i++) sum+=fArray[i]; return sum;}
void Reset(Float_t val)
{memset(fArray, 0, fN*sizeof(Float_t));}
void Reset(Float_t val)
{for (Int_t i=0;i<fN;i++) fArray[i] = val;}
