Reimplemented from TObject.

Reimplemented in TSystemDirectory.

Definition at line 69 of file TSystemFile.cxx.

◆ Copy() [1/2]

void TSystemFile::Copy ( const char *  to)

◆ Copy() [2/2]

void TSystemFile::Copy ( TObject named) const
inlinevirtual

inlinevirtual

Delete this object.

Typically called as a command via the interpreter. Normally use "delete" operator when object has been allocated on the heap.

Reimplemented from TObject.

Definition at line 57 of file TSystemFile.h.

◆ DrawClass()

void TSystemFile::DrawClass ( ) const
inlinevirtual

Draw class inheritance tree of the class to which this object belongs.

If a class B inherits from a class A, description of B is drawn on the right side of description of A. Member functions overridden by B are shown in class A with a blue line crossing-out the corresponding member function. The following picture is the class inheritance tree of class TPaveLabel:

Reimplemented from TObject.

Definition at line 52 of file TSystemFile.h.

◆ DrawClone()

TObject* TSystemFile::DrawClone ( Option_t option) const
inlinevirtual

virtual

rename this file

Definition at line 162 of file TSystemFile.cxx.

◆ SetDrawOption()

void TSystemFile::SetDrawOption ( Option_t option)
inlinevirtual

Set drawing option for object.

This option only affects the drawing style and is stored in the option field of the TObjOptLink supporting a TPad's primitive list (TList). Note that it does not make sense to call object.SetDrawOption(option) before having called object.Draw().

Reimplemented from TObject.

inlinevirtual

◆ SetName()

void TSystemFile::SetName ( const char *  name)
inlinevirtual

Set the name of the TNamed.

WARNING: if the object is a member of a THashTable or THashList container the container must be Rehash()'ed after SetName(). For example the list of objects in the current directory is a THashList.

Reimplemented from TNamed.

Definition at line 55 of file TSystemFile.h.

◆ SetTitle()

void TSystemFile::SetTitle ( const char *  title)
