Constructor & Destructor Documentation

◆ TDirectory() [1/3]

TDirectory::TDirectory ( const TDirectory & directory )

protected

Copy constructor.

Definition at line 90 of file TDirectory.cxx.

◆ TDirectory() [2/3]

TDirectory::TDirectory ( )

Directory default constructor.

Definition at line 46 of file TDirectory.cxx.

◆ TDirectory() [3/3]

TDirectory::TDirectory	(	const char *	name,
		const char *	title,
		Option_t *	option = `""`,
		TDirectory *	initMotherDir = `0`
	)

Create a new Directory.

A new directory with name,title is created in the current directory The directory header information is immediately saved in the file A new key is added in the parent directory

When this constructor is called from a class directly derived from TDirectory, the third argument classname MUST be specified. In this case, classname must be the name of the derived class.

Note that the directory name cannot contain slashes.

Definition at line 65 of file TDirectory.cxx.

Member Function Documentation

◆ Add()

virtual void TDirectory::Add	(	TObject *	obj,
		Bool_t	replace = `kFALSE`
	)

inlinevirtual

Reimplemented in TDirectoryFile.

Definition at line 118 of file TDirectory.h.

◆ AddDirectory()

void TDirectory::AddDirectory ( Bool_t add = kTRUE )

static

Sets the flag controlling the automatic add objects like histograms, TGraph2D, etc in memory.

By default (fAddDirectory = kTRUE), these objects are automatically added to the list of objects in memory. Note that in the classes like TH1, TGraph2D supporting this facility, one object can be removed from its support directory by calling object->SetDirectory(0) or object->SetDirectory(dir) to add it to the list of objects in the directory dir.

NOTE that this is a static function. To call it, use:

TDirectory::AddDirectory

static void AddDirectory(Bool_t add=kTRUE)

Sets the flag controlling the automatic add objects like histograms, TGraph2D, etc in memory.

Definition: TDirectory.cxx:171

Definition at line 171 of file TDirectory.cxx.

		TDirectory *	motherDir = `0`
	)

virtual

Initialise directory to defaults.

If directory is created via default ctor (when dir is read from file) don't add it here to the directory since its name is not yet known. It will be added to the directory in TKey::ReadObj().

Reimplemented in TDirectoryFile.

Definition at line 237 of file TDirectory.cxx.

◆ Cd()

Bool_t TDirectory::Cd ( const char * path )

static

Change current directory to "path".

The absolute path syntax is: file.root:/dir1/dir2 where file.root is the file and `/dir1/dir2 the desired subdirectory in the file. Relative syntax is relative to the current directory gDirectory, e.g.: ../aa.

Returns kTRUE in case of success.

Definition at line 541 of file TDirectory.cxx.

◆ cd()

Bool_t TDirectory::cd ( const char * path = 0 )

virtual

Change current directory to "this" directory.

Using path one can change the current directory to "path". The absolute path syntax is: file.root:/dir1/dir2 where file.root is the file and /dir1/dir2 the desired subdirectory in the file.

Relative syntax is relative to "this" directory. E.g: ../aa.

Returns kTRUE in case of success.

Reimplemented in TDirectoryFile.

Definition at line 497 of file TDirectory.cxx.

◆ cd1()

Bool_t TDirectory::cd1 ( const char * apath )

protected

flag to add histograms, graphs,etc to the directory

Change current directory to "this" directory.

Using path one can change the current directory to "path". The absolute path syntax is: file.root:/dir1/dir2 where file.root is the file and /dir1/dir2 the desired subdirectory in the file.

Relative syntax is relative to "this" directory. E.g: ../aa.

Returns kFALSE in case path does not exist.

Definition at line 515 of file TDirectory.cxx.

◆ Cd1()

Bool_t TDirectory::Cd1 ( const char * apath )

staticprotected

◆ CloneObject()

TObject * TDirectory::CloneObject	(	const TObject *	obj,
		Bool_t	autoadd = `kTRUE`
	)

virtual

Clone an object.

This function is called when the directory is not a TDirectoryFile. This version has to load the I/O package, hence via Cling.

If autoadd is true and if the object class has a DirectoryAutoAdd function, it will be called at the end of the function with the parameter gDirector. This usually means that the object will be appended to the current ROOT directory.

Reimplemented in TDirectoryFile.

Definition at line 328 of file TDirectory.cxx.

◆ Close()

void TDirectory::Close ( Option_t * option = "" )

virtual

Delete all objects from memory and directory structure itself.

if option is "slow", iterate through the containers in a way to can handle 'external' modification (induced by recursions) if option is "nodelete", write the TDirectory but do not delete the contained objects.

Reimplemented in TDirectoryFile, TFile, TSQLFile, TXMLFile, TNetFile, and TParallelMergingFile.

Definition at line 584 of file TDirectory.cxx.

Definition at line 1238 of file TDirectory.cxx.

◆ Delete()

void TDirectory::Delete ( const char * namecycle = "" )

virtual

Delete Objects or/and keys in a directory.

namecycle has the format name;cycle
namecycle = "" same as namecycle ="T*"
name = * means all
cycle = * means all cycles (memory and keys)
cycle = "" or cycle = 9999 ==> apply to a memory object When name=* use T* to delete subdirectories also

To delete one directory, you must specify the directory cycle, eg. file.Delete("dir1;1");

examples:

foo : delete object named foo in memory
foo* : delete all objects with a name starting with foo
foo;1 : delete cycle 1 of foo on file
foo;* : delete all cycles of foo on file and also from memory
*;2 : delete all objects on file having the cycle 2
*;* : delete all objects from memory and file

◆ Get()

TObject * TDirectory::Get ( const char * namecycle )

virtual

Return pointer to object identified by namecycle.

namecycle has the format name;cycle

name = * is illegal, cycle = * is illegal
cycle = "" or cycle = 9999 ==> apply to a memory object

examples:

foo : get object named foo in memory if object is not in memory, try with highest cycle from file
foo;1 : get cycle 1 of foo on file

The retrieved object should in principle derive from TObject. If not, the function TDirectory::GetObject should be called. However, this function will still work for a non-TObject, providing that the calling application cast the return type to the correct type (which is the actual type of the object).

NOTE:

The method GetObject offer better protection and avoid the need for any cast:

MyClass *obj;
directory->GetObject("some object",obj);
if (obj) { ... the object exist and inherits from MyClass ... }

VERY IMPORTANT NOTE:

In case the class of this object derives from TObject but not as a first inheritance, one must use dynamic_cast<>().

Example 1: Normal case:

class MyClass : public TObject, public AnotherClass

TObject

Mother of all ROOT objects.

Definition: TObject.h:37

then on return, one can do:

MyClass *obj = (MyClass*)directory->Get("some object of MyClass");

Example 2: Special case:

class MyClass : public AnotherClass, public TObject

then on return, one must do:

MyClass *obj = dynamic_cast<MyClass*>(directory->Get("some object of MyClass"));

Of course, dynamic_cast<> can also be used in the example 1.

◆ GetDirectory()

TDirectory * TDirectory::GetDirectory	(	const char *	apath,

	)

virtual

Find a directory using apath.

It apath is null or empty, returns "this" directory. Otherwise use apath to find a directory. The absolute path syntax is: file.root:/dir1/dir2

where file.root is the file and /dir1/dir2 the desired subdirectory in the file. Relative syntax is relative to "this" directory. E.g: ../aa. Returns 0 in case path does not exist. If printError is true, use Error with 'funcname' to issue an error message.

cycle = "" or cycle = 9999 ==> apply to a memory object

VERY IMPORTANT NOTE:

The calling application must cast the returned pointer to the type described by the 2 arguments (i.e. cl):

MyClass *obj = (MyClass*)directory->GetObjectChecked("some object of MyClass","MyClass"));

Note: We recommend using the method TDirectory::GetObject:

MyClass *obj = 0;

virtual Int_t TDirectory::Write	(	const char *	name = `0`,

		Int_t	bufsize = `0`
	)		const

inlinevirtual

Write this object to the current directory.

The data structure corresponding to this object is serialized. The corresponding buffer is written to the current directory with an associated key with name "name".

Writing an object to a file involves the following steps:

Creation of a support TKey object in the current directory. The TKey object creates a TBuffer object.
The TBuffer object is filled via the class::Streamer function.
If the file is compressed (default) a second buffer is created to hold the compressed buffer.
Reservation of the corresponding space in the file by looking in the TFree list of free blocks of the file.
The buffer is written to the file.

Bufsize can be given to force a given buffer size to write this object. By default, the buffersize will be taken from the average buffer size of all objects written to the current file so far.

If a name is specified, it will be the name of the key. If name is not given, the name of the key will be the name as returned by GetName().

The option can be a combination of: kSingleKey, kOverwrite or kWriteDelete Using the kOverwrite option a previous key with the same name is overwritten. The previous key is deleted before writing the new object. Using the kWriteDelete option a previous key with the same name is deleted only after the new object has been written. This option is safer than kOverwrite but it is slower. The kSingleKey option is only used by TCollection::Write() to write a container with a single key instead of each object in the container with its own key.

An object is read from the file into memory via TKey::Read() or via TObject::Read().

The function returns the total number of bytes written to the file. It returns 0 if the object cannot be written.
