RooTemplateProxy< T > Class Template Reference

template<class T>
class RooTemplateProxy< T >

Introduction

A RooTemplateProxy is used to hold references to other RooFit objects in an expression tree. A RooGaussian(..., x, mean, sigma) can e.g. store references to x, mean, sigma as

RooTemplateProxy<RooAbsReal> _x;
RooTemplateProxy<RooAbsReal> _mean;
RooTemplateProxy<RooAbsReal> _sigma;

Now, the values of these three can be accessed, and the template argument ensures that only objects that evaluate to real numbers (RooAbsReal) can be stored in such a proxy. These can e.g. be variables, PDFs and functions. To store an object that's a RooCategory, one would, for example, use

RooTemplateProxy<RooCategory> _category;

Since ROOT 6.22, the proxy can be used like a pointer to an instance of the template argument. For this, it provides operator* and operator->, e.g.

double oldValue = _x->getVal(normalisationSet);
*_x = 17.;

RooTemplateProxy's base class RooArgProxy registers the proxied objects as "servers" of the object that holds the proxy. When the value of the proxied object is changed, the owner is notified, and can recalculate its own value. Renaming or exchanging objects that serve values to the owner of the proxy is handled automatically.

Modernisation of proxies in ROOT 6.22

In ROOT 6.22, the classes RooRealProxy and RooCategoryProxy were replaced by RooTemplateProxy<class T>.

Two typedefs have been defined for backward compatibility:

• RooRealProxy = RooTemplateProxy<RooAbsReal>. Any generic object that converts to a real value.
• RooCategoryProxy = RooTemplateProxy<RooAbsCategory>. Any category object.

To modernise a class, one can change the template argument of the proxy to the most appropriate type, and increment the class version of the owner.

RooFit before ROOT 6.22

RooFit starting with ROOT 6.22

// In .h: Declare member RooRealProxy pdfProxy; ClassDefOverride(MyPdf, 1) }; // In .cxx: Initialise proxy in constructor // The proxy will accept any RooAbsArg, so the type of // "thePdf" has to be checked manually. MyPdf::MyPdf(name, title, ...) : pdfProxy("pdfProxy", "Proxy holding a PDF", this, thePdf) { [ Extra checking here ... ] } // In .cxx: Accessing the proxy RooAbsArg* absArg = pdfProxy.absArg(); RooAbsPdf* pdf = dynamic_cast<RooAbsPdf*>(absArg); assert(pdf); // Manual type checking ... pdf->fitTo(...);

// In .h: Declare member RooTemplateProxy<RooAbsPdf> pdfProxy; ClassDefOverride(MyPdf, 2) }; // In .cxx: Initialise proxy in constructor // The program will not compile if "thePdf" is not a // type deriving from RooAbsPdf MyPdf::MyPdf(name, title, ...) : pdfProxy("pdfProxy", "Proxy holding a PDF", this, thePdf) { } // In .cxx: Accessing the proxy pdfProxy->fitTo(...);

How to modernise old code

1. Choose the proper template argument for the proxy.
   • If a PDF is stored: RooTemplateProxy<RooAbsPdf>.
   • If a real-valued object is stored: RooTemplateProxy<RooAbsReal>.
   • If a category is stored: RooTemplateProxy<RooCategory>.
   • If a variable is stored (i.e. one wants to be able to assign values to it): RooTemplateProxy<RooRealVar> Other template arguments are possible, as long as they derive from RooAbsArg.
2. Increment the class version of the owning class.
3. Make sure that the right type is passed in the constructor of the proxy.
4. Always use proxy-> and *proxy to work with the stored object. No need to cast.

5. Only if necessary If errors about missing symbols connected to RooTemplateProxy appear at link time, a specific template instantiation for RooTemplateProxy is not yet in ROOT's dictionaries. These two lines should be added to the LinkDef.h of the project:

   #pragma link C++ class RooTemplateProxy<RooMultiCategory>+;
   #pragma read sourceClass="RooCategoryProxy" targetClass="RooTemplateProxy<RooMultiCategory>"

   Replace RooMultiCategory by the proper type. If the proxy was holding a real-valued object, use sourceClass="RooRealProxy".

   The first line adds the proxy class to the dictionary, the second line enables reading a legacy RooCategoryProxy from a file, and converting it to the new type-safe proxy. If no old proxies have to be read from files, this line can be omitted.

   If the template instantiation that triggered the missing symbols seems to be a very common instantiation, request for it to be added to RooFit by creating a pull request for ROOT. If it is rather uncommon, it is sufficient to add it to the LinkDef.h of the local project only.

Legacy interface
In ROOT versions before 6.22, RooFit didn't have this typed proxy. Therefore, a number of functions for forwarding calls to the proxied objects were necessary. The functions in this group can all be replaced by directly accessing the proxied objects using e.g. the member access operator like proxy->function() or by dereferencing like *proxy = value. For this to work, choose the template argument appropriately. That is, if the proxy stores a PDF, use RooTemplateProxy<RooAbsPdf>, etc..

	Assign a new value to the object pointed to by the proxy.
RooTemplateProxy< T > &	operator= (const std::string &newState)
	Set a category state using its state name. This function can only work for category-type proxies.

	Check if the range has a lower bound. This requires the payload to be RooAbsRealLValue or derived.

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)

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)

Note

This function must be non-virtual as it can be used on destructed (but not yet modified) memory. This is used for example in TClonesArray to record the element that have been destructed but not deleted and thus are ready for re-use (by operator new with placement).

Returns

true if this object's destructor has been run.

Definition at line 186 of file TObject.h.

IsEqual()

lvptr() [1/4]

template<class T>

const LValue_t * RooTemplateProxy< T >::lvptr ( const LValue_t * ) const

inlineprivate

Return l-value pointer to contents.

If the contents derive from RooAbsLValue or RooAbsCategoryLValue, the conversion is safe, and the function directly returns the pointer using a static_cast. If the template parameter of this proxy is not an LValue type, then

• in a debug build, a dynamic_cast with an assertion is used.
• in a release build, a static_cast is forced, irrespective of what the type of the object actually is. This is dangerous, but equivalent to the behaviour before refactoring the RooFit proxies.

  Deprecated

  This function is unnecessary if the template parameter is RooAbsRealLValue (+ derived types) or RooAbsCategoryLValue (+derived types), as arg() will always return the correct type.

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.

Definition at line 989 of file TObject.cxx.

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.
