ROOT::TFilePtr ROOT::TFilePtr::Create ( std::string_view  name )

static

Open a file with name for reading and writing.

Fail (return an invalid TFilePtr) if a file with this name already exists.

Definition at line 79 of file TFile.cxx.

ROOT::TFilePtr ROOT::TFilePtr::OpenForRead ( std::string_view  name )

static

Open a file with name for reading.

Definition at line 75 of file TFile.cxx.

ROOT::TFilePtr ROOT::TFilePtr::OpenForUpdate ( std::string_view  name )

static

Open an existing file with name for reading and writing.

If a file with that name does not exist, an invalid TFilePtr will be returned.

Definition at line 87 of file TFile.cxx.

ROOT::TFilePtr::operator bool ( ) const

inline

Check the validity of the file pointer.

Definition at line 94 of file TFile.h.

Internal::TFileImplBase* ROOT::TFilePtr::operator-> ( )

inline

Dereference the file pointer, giving access to the TFileImplBase object.

Definition at line 87 of file TFile.h.

const Internal::TFileImplBase* ROOT::TFilePtr::operator-> ( ) const

inline

Dereference the file pointer, giving access to the TFileImplBase object.

const overload.

Definition at line 91 of file TFile.h.

ROOT::TFilePtr ROOT::TFilePtr::Recreate ( std::string_view  name )

static

Open a file with name for reading and writing.

If a file with this name already exists, delete it and create a new one. Else simply create a new file.
