Mother of all ROOT objects.

The TObject class provides default behaviour and protocol for all objects in the ROOT system. It provides protocol for object I/O, error handling, sorting, inspection, printing, drawing, etc. Every object which inherits from TObject can be stored in the ROOT collection classes.

TObject's bits can be used as flags, bits 0 - 13 and 24-31 are reserved as global bits while bits 14 - 23 can be used in different class hierarchies (watch out for overlaps).

Enumerator

kOnlyPrepStep

Used to request that the class specific implementation of TObject::Write just prepare the objects to be ready to be written but do not actually write them into the TBuffer.

This is just for example by TBufferMerger to request that the TTree inside the file calls TTree::FlushBaskets (outside of the merging lock) and TBufferMerger will later ask for the write (inside the merging lock). To take advantage of this feature the class needs to overload TObject::Write and use this enum value accordingly. (See TTree::Write and TObject::Write) Do not use, this feature will be migrate to the Merge function (See TClass and TTree::Merge)

Constructor & Destructor Documentation

◆ TObject() [1/2]

TObject::TObject ( )

inline

TObject constructor.

It sets the two data words of TObject to their initial values. The unique ID is set to 0 and the status word is set depending if the object is created on the stack or allocated on the heap. Depending on the ROOT environment variable "Root.MemStat" (see TEnv) the object is added to the global TObjectTable for bookkeeping.

Definition at line 241 of file TObject.h.

◆ TObject() [2/2]

TObject::TObject ( const TObject & object )

inline

TObject copy ctor.

Definition at line 259 of file TObject.h.

◆ ~TObject()

TObject::~TObject ( )

virtual

TObject destructor.

Removes object from all canvases and object browsers if observer bit is on and remove from the global object table.

Definition at line 79 of file TObject.cxx.

Member Function Documentation

◆ AbstractMethod()

void TObject::AbstractMethod ( const char * method ) const

Use this method to implement an "abstract" method that you don't want to leave purely abstract.

Definition at line 933 of file TObject.cxx.

◆ AddToTObjectTable()

void TObject::AddToTObjectTable ( TObject * op )

staticprivate

Private helper function which will dispatch to TObjectTable::AddObj.

Included here to avoid circular dependency between header files.

Definition at line 96 of file TObject.cxx.

◆ AppendPad()

void TObject::AppendPad ( Option_t * option = "" )

virtual

Append graphics object to current pad.

In case no current pad is set yet, create a default canvas with the name "c1".

Definition at line 105 of file TObject.cxx.

◆ Browse()

void TObject::Browse ( TBrowser * b )

virtual

Browse object. May be overridden for another default action.

Reimplemented in TASImage, TRecorder, TEfficiency, TGraph2D, TChain, TTree, TFolder, TMacro, TRemoteObject, TROOT, TStyle, TSystemDirectory, TSystemFile, TTask, TCollection, TPair, TBaseClass, TClass, TGeoManager, TGeoNode, TGeoVolume, TGeoOverlap, TGeoTrack, TCanvas, TPad, TRatioPlot, TAxis3D, TGeometry, TNode, THbookBranch, THbookFile, THbookKey, TF1, TGraph, TH1, THnBase, ROOT::Internal::THnBaseBrowsable, THStack, TMultiDimFit, TMultiGraph, TPrincipal, TKey, TKeyMapFile, TMapFile, TSPlot, TDatabasePDG, TGenerator, TParticleClassPDG, TAlienDirectoryEntry, TAlienDirectory, TAlienJobStatus, TAlienMasterJob, TAlienMasterJobStatus, TApplicationRemote, TProof, TProofChain, RooPlot, TBranch, TVirtualBranchBrowsable, TCollectionPropertyBrowsable, TBranchClones, TBranchElement, TBranchObject, TBranchSTL, TLeaf, TNtuple, TNtupleD, TTreePerfStats, TDirectory, TDirectoryFile, and TQueryResult.

Definition at line 119 of file TObject.cxx.

◆ CheckedHash()

ULong_t TObject::CheckedHash ( )

inline

Check and record whether this class has a consistent Hash/RecursiveRemove setup (*) and then return the regular Hash value for this object.

The intent is for this routine to be called instead of directly calling the function Hash during "insert" operations. See TObject::HasInconsistenTObjectHash();

(*) The setup is consistent when all classes in the class hierarchy that overload TObject::Hash do call ROOT::CallRecursiveRemoveIfNeeded in their destructor. i.e. it is safe to call the Hash virtual function during the RecursiveRemove operation.

Definition at line 311 of file TObject.h.

◆ ClassName()

const char * TObject::ClassName ( ) const

virtual

Returns name of class to which the object belongs.

Definition at line 128 of file TObject.cxx.

Definition at line 115 of file TObject.h.

◆ Clone()

TObject * TObject::Clone ( const char * newname = "" ) const

virtual

Make a clone of an object using the Streamer facility.

If the object derives from TNamed, this function is called by TNamed::Clone. TNamed::Clone uses the optional argument to set a new name to the newly created object.

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

Definition at line 144 of file TObject.cxx.

◆ Compare()

Int_t TObject::Compare ( const TObject * obj ) const

virtual

Compare abstract method.

Must be overridden if a class wants to be able to compare itself with other objects. Must return -1 if this is smaller than obj, 0 if objects are equal and 1 if this is larger than obj.

Reimplemented in TEnvRec, TFileInfo, TNamed, TObjString, TParameter< AParamType >, TParameter< Long64_t >, TUrl, TCollection, TGeoBranchArray, TGeoOverlap, TStructNode, TStructNodeProperty, TClassDocInfo, TDSetElement, TSlaveInfo, TSlave, TPerfEvent, RooAbsArg, RooDouble, and RooInt.

◆ HasInconsistentHash()

Bool_t TObject::HasInconsistentHash ( ) const

inline

Return true is the type of this object is known to have an inconsistent setup for Hash and RecursiveRemove (i.e.

missing call to RecursiveRemove in destructor).

Note: Since the consistency is only tested for during inserts, this routine will return true for object that have never been inserted whether or not they have a consistent setup. This has no negative side-effect as searching for the object with the right or wrong Hash will always yield a not-found answer (Since anyway no hash can be guaranteed unique, there is always a check)

◆ Read()

Int_t TObject::Read ( const char * name )

virtual

◆ SaveAs()

void TObject::SaveAs	(	const char *	filename = `""`,
		Option_t *	option = `""`
	)		const

virtual

Save this object in the file specified by filename.

if "filename" contains ".root" the object is saved in filename as root binary file.
if "filename" contains ".xml" the object is saved in filename as a xml ascii file.
if "filename" contains ".cc" the object is saved in filename as C code independant from ROOT. The code is generated via SavePrimitive(). Specific code should be implemented in each object to handle this option. Like in TF1::SavePrimitive().
otherwise the object is written to filename as a CINT/C++ script. The C++ code to rebuild this object is generated via SavePrimitive(). The "option" parameter is passed to SavePrimitive. By default it is an empty string. It can be used to specify the Draw option in the code generated by SavePrimitive.

The function is available via the object context menu.

◆ Write() [2/2]

Int_t TObject::Write	(	const char *	name = `0`,
		Int_t	option = `0`,
		Int_t	bufsize = `0`
	)		const

virtual

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. NOTE: Neither kOverwrite nor kWriteDelete reduces the size of a TFile– the space is simply freed up to be overwritten; in the case of a TTree, it is more complicated. If one opens a TTree, appends some entries, then writes it out, the behaviour is effectively the same. If, however, one creates a new TTree and writes it out in this way, only the metadata is replaced, effectively making the old data invisible without deleting it. TTree::Delete() can be used to mark all disk space occupied by a TTree as free before overwriting its metadata this way. 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.

Reimplemented in TSQLFile, TXMLFile, TDirectory, TBuffer, TParallelMergingFile, TCollection, TMap, TTree, TFile, and TDirectoryFile.
