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)

Member Function Documentation

Abort()

void TSelector::Abort ( const char * why, EAbort what = kAbortProcess )

virtualinherited

Abort processing.

If what = kAbortProcess, the Process() loop will be aborted. If what = kAbortFile, the current file in a chain will be aborted and the processing will continue with the next file, if there is no next file then Process() will be aborted. Abort() can also be called from Begin(), SlaveBegin(), Init() and Notify(). After abort the Terminate() method is always called. The abort flag can be checked in these methods using GetAbort().

Definition at line 107 of file TSelector.cxx.

AbstractMethod()

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

inherited

Call this function within a function that you don't want to define as purely virtual, in order not to force all users deriving from that class to implement that maybe (on their side) unused function; but at the same time, emit a run-time warning if they try to call it, telling that it is not implemented in the derived class: action must thus be taken on the user side to override it.

In other word, this method acts as a "runtime purely virtual" warning instead of a "compiler purely virtual" error.

Warning

This interface is a legacy function that is no longer recommended to be used by new development code.

Note

The name "AbstractMethod" does not imply that it's an abstract method in the strict C++ sense.

Definition at line 1149 of file TObject.cxx.

AddToTObjectTable()

void TObject::AddToTObjectTable ( TObject * op )

staticprivateinherited

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

Included here to avoid circular dependency between header files.

Definition at line 195 of file TObject.cxx.

AppendPad()

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

virtualinherited

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 204 of file TObject.cxx.

Begin()

void TSelectorDraw::Begin ( TTree * tree )

overridevirtualinherited

Called every time a loop on the tree(s) starts.

Reimplemented from TSelector.

CheckedHash()

ULong_t TObject::CheckedHash ( )

inlineinherited

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.

       = sqrt(x)         : draw distribution of sqrt(x)
       = x*y/z
       = y:sqrt(x) 2-Dim distribution of y versus sqrt(x)

selection is an expression with a combination of the columns

Example:

selection = "x<y && sqrt(z)>3.2"

in a selection all the C++ operators are authorized

Return false if any of the variable is not compilable.

GetVal()

Double_t * TSelectorDraw::GetVal ( Int_t i ) const

virtualinherited

Return the last values corresponding to the i-th component of the formula being processed (where the component are ':' separated).

The actual number of entries is:

GetSelectedRows() % tree->GetEstimate()

Note GetSelectedRows currently returns the actual number of values plotted and thus if the formula contains arrays, this number might be greater than the number of entries in the trees.

By default TTree::Draw creates the arrays obtained with all GetVal and GetW with a length corresponding to the parameter fEstimate. By default fEstimate=10000 and can be modified via TTree::SetEstimate. A possible recipe is to do

tree->SetEstimate(tree->GetEntries());

You must call SetEstimate if the expected number of selected rows is greater than 10000.

See TTree::Draw for additional details.

Hash()

ULong_t TObject::Hash ( ) const

virtualinherited

Return hash value for this object.

Note: If this routine is overloaded in a derived class, this derived class should also add

ROOT::CallRecursiveRemoveIfNeeded(*this)

Otherwise, when RecursiveRemove is called (by ~TObject or example) for this type of object, the transversal of THashList and THashTable containers will will have to be done without call Hash (and hence be linear rather than logarithmic complexity). You will also see warnings like

Error in <ROOT::Internal::TCheckHashRecursiveRemoveConsistency::CheckRecursiveRemove>: The class SomeName overrides
TObject::Hash but does not call TROOT::RecursiveRemove in its destructor.

Reimplemented in RooLinkedList, TASImagePlugin, TASPluginGS, TCollection, TEnvRec, TGObject, TGPicture, TIconBoxThumb, TImagePlugin, TNamed, TObjString, TPad, TPair, TParameter< AParamType >, TParameter< Long64_t >, TPave, and TStatistic.

Definition at line 539 of file TObject.cxx.

HasInconsistentHash()

Bool_t TObject::HasInconsistentHash ( ) const

inlineinherited

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)

Definition at line 366 of file TObject.h.

ImportOutput()

void TSelector::ImportOutput ( TList * output )

virtualinherited

Imports the content of 'output' in the internal output list.

Existing content in the output list is discarded (unless found also in 'output'). In particular, if 'output' is nullptr or empty, reset the internal list. On return, the content of 'output' is cleared to avoid double deletion issues. (The caller is responsible of 'output' as container: its content is transferred under the selector ownership).

Paint()

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

virtualinherited

This method must be overridden if a class wants to paint itself.

The difference between Paint() and Draw() is that when a object draws itself it is added to the display list of the pad in which it is drawn (and automatically redrawn whenever the pad is redrawn). While paint just draws the object without adding it to the pad display list.

Process()

bool TSelectorDraw::Process ( Long64_t )

inlineoverridevirtualinherited

The Process() function is called for each entry in the tree to be processed.

The entry argument specifies which entry in the currently loaded tree is to be processed. It can be passed to either t01::GetEntry() or TBranch::GetEntry() to read either all or the required parts of the data.

This function should contain the "body" of the analysis. It can contain simple or elaborate selection criteria, run algorithms on the data of the event and typically fill histograms.

The processing can be stopped by calling Abort().

Use fStatus to set the return value of TTree::Process().

The return value is currently not used.

WARNING when a selector is used with a TChain, you must use the pointer to the current TTree to call GetEntry(entry). The entry is always the local entry number in the current tree. Assuming that fChain is the pointer to the TChain being processed, use: fChain->GetTree()->GetEntry(entry).

Reimplemented from TSelector.

Definition at line 111 of file TSelectorDraw.h.

ProcessCut()

bool TSelector::ProcessCut ( Long64_t )

virtualinherited

This method is called before processing entry.

It is the user's responsibility to read the corresponding entry in memory (may be just a partial read). The function returns true if the entry must be processed, false otherwise. This method is obsolete, use Process().

WARNING when a selector is used with a TChain: in the Process, ProcessCut, ProcessFill function, you must use the pointer to the current Tree to call GetEntry(entry). entry is always the local entry number in the current tree. Assuming that fChain is the pointer to the TChain being processed, use fChain->GetTree()->GetEntry(entry);

SaveAs()

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

virtualinherited

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 independent 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 = nullptr, Int_t option = 0, Int_t bufsize = 0 ) const

virtualinherited

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.
