TCutG Class Reference

Graphical cut class.

A TCutG object is a closed polygon defining a closed region in a x,y plot. It can be created via the graphics editor option "CutG" or directly by invoking its constructor. The first and last points should be the same.

To create a TCutG via the graphics editor, use the left button to select the points building the contour of the cut. Click on the right button to close the TCutG. When it is created via the graphics editor, the TCutG object is named "CUTG". It is recommended to immediately change the name by using the context menu item "SetName". When the graphics editor is used, the names of the variables X,Y are automatically taken from the current pad title.

Example:

Assume a TTree object T and:

Root > T.Draw("abs(fMomemtum):fEtot")

the TCutG members fVarX, fVary will be set to:

fVarx = fEtot
fVary = abs(fMomemtum)

A graphical cut can be used in a TTree selection expression:

Root > T.Draw("fEtot","cutg1")

where "cutg1" is the name of an existing graphical cut.

Note that, as shown in the example above, a graphical cut may be used in a selection expression when drawing TTrees expressions of 1-d, 2-d or 3-dimensions. The expressions used in TTree::Draw can reference the variables in the fVarX, fVarY of the graphical cut plus other variables.

When the TCutG object is created by TTree::Draw, it is added to the list of special objects in the main TROOT object pointed by gROOT. To retrieve a pointer to this object from the code or command line, do:

TCutG *mycutg;
mycutg = (TCutG*)gROOT->GetListOfSpecials()->FindObject("CUTG")
mycutg->SetName("mycutg");

When the TCutG is not created via TTree::Draw, one must set the variable names corresponding to x,y if one wants to use the cut as input to TTree::Draw,eg

TCutG *cutg = new TCutG("mycut",6);
cutg->SetVarX("y");
cutg->SetVarY("x");
cutg->SetPoint(0,-0.3586207,1.509534);
cutg->SetPoint(1,-1.894181,-0.529661);
cutg->SetPoint(2,0.07780173,-1.21822);
cutg->SetPoint(3,-1.0375,-0.07944915);
cutg->SetPoint(4,0.756681,0.1853814);
cutg->SetPoint(5,-0.3586207,1.509534);

Example of use of a TCutG in TTree::Draw:

tree.Draw("x:y","mycutg && z>0 && sqrt(x)>1")

A Graphical cut may be drawn via TGraph::Draw. It can be edited like a normal TGraph. Being a TGraph the drawing options and behavior relatives to graphs apply. They are listed in the TGraphPainter description. See in particular "Graphs in logarithmic scale".

A Graphical cut may be saved to a file via TCutG::Write.

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

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.

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.

Hash()

ULong_t TNamed::Hash ( ) const

inlineoverridevirtualinherited

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 from TObject.

Definition at line 51 of file TNamed.h.

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)

• 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.

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.
