Constructor & Destructor Documentation

◆ TArrayD() [1/4]

TArrayD::TArrayD ( )

Default TArrayD ctor.

Definition at line 26 of file TArrayD.cxx.

◆ TArrayD() [2/4]

TArrayD::TArrayD ( Int_t  n)

Create TArrayD object and set array size to n doubles.

Definition at line 34 of file TArrayD.cxx.

◆ TArrayD() [3/4]

TArrayD::TArrayD ( Int_t  n,
const Double_t array 
)

Create TArrayD object and initialize it with values of array.

Definition at line 43 of file TArrayD.cxx.

◆ TArrayD() [4/4]

Member Function Documentation

◆ AddAt()

void TArrayD::AddAt ( Double_t  c,
Int_t  i 
)

Set the double c value at position i in the array.

Check for out of bounds. Warning: the name of the method is misleading, it actually overwrites the position i.

Definition at line 94 of file TArrayD.cxx.

◆ Adopt()

void TArrayD::Adopt ( Int_t  n,
Double_t arr 
)

Adopt array arr into TArrayD, i.e.

don't copy arr but use it directly in TArrayD. User may not delete arr, TArrayD dtor will do it.
