void	AbstractMethod (const char *method) const
	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.

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.

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.

Analyze()

void TFormula::Analyze ( const char * schain, Int_t & err, Int_t offset = 0 )

virtualinherited

Analyze a sub-expression in one formula.

Special cases for normalized gaussian or landau distributions

the expression "gaus" is a substitute for

[0]*exp(-0.5*((x-[1])/[2])**2)

to obtain a standard normalized gaussian, use "gausn" instead of "gaus" the expression "gausn" is a substitute for

[0]*exp(-0.5*((x-[1])/[2])**2)/(sqrt(2*pi)*[2]))

WARNING: gaus and gausn are mutually exclusive in the same expression.

In the same way the expression "landau" is a substitute for

[0]*TMath::Landau(x,[1],[2],kFALSE)

to obtain a standard normalized landau, use "landaun" instead of "landau" the expression "landaun" is a substitute for

[0]*TMath::Landau(x,[1],[2],kTRUE)

WARNING: landau and landaun are mutually exclusive in the same expression.

Boolean optimization (kBoolOptmize) :

Those pseudo operation are used to implement lazy evaluation of && and ||. When the left hand of the expression if false (respectively true), the evaluation of the right is entirely skipped (since it would not change the value of the expression).

&& 142 11 (one operation on right) 142 21 (2 operations on right) || 142 12 (one operation on right) 142 22 (2 operations on right)

Special functions

By default, the formula is assigned fNumber=0. However, the following formula built with simple functions are assigned fNumber:

 "gaus"      100  (or gausn)
 "xygaus"    110
 "expo"      200
 "polN"      300+N
 "landau"    400
 "xylandau"  410

Note that expressions like gaus(0), expo(1) will force fNumber=0

Warning when deriving a class from TFormula

If you overload this member function, you also HAVE TO never call the constructor:

GetExpFormula()

TString TFormula::GetExpFormula ( Option_t * option = "" ) const

virtualinherited

Reconstruct the formula expression from the internal TFormula member variables.

This function uses the internal member variables of TFormula to construct the mathematical expression associated with the TFormula instance. This function can be used to get an expanded version of the expression originally assigned to the TFormula instance, i.e. that the string returned by GetExpFormula() doesn't depend on other TFormula object names.

if option contains "p" the returned string will contain the formula expression with symbolic parameters, eg [0] replaced by the actual value of the parameter. Example: if expression in formula is: "[0]*(x>-[1])+[2]*exp(-[3]*x)" and parameters are 3.25,-4.01,4.44,-0.04, GetExpFormula("p") will return: "(3.25*(x>+4.01))+(4.44*exp(+0.04*x))"

Note

Floats when option contains "p" are printed with g (6 decimals); if you need more precision, use instead the non-v5 version of this class.

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.

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)

Optimize()

void TFormula::Optimize ( )

virtualinherited

MI include.

Optimize formula

• Minimize the number of operands
  1. several operands are glued together
  2. some primitive functions glued together - exemp. (x+y) => PlusXY(x,y)
  3. maximize number of standard calls minimizing number of jumps in Eval cases
  4. variables, parameters and constants are mapped - using fOperOfssets0 Eval procedure use direct acces to data (only one corresponding case statement in eval procedure)

     pdata[operand={Var,Par,Const}][offset]
     pdata[fOperOffsets0[i]][fOperOffset1[i+1]]

• The fastest evaluation function is chosen at the end
  1. fOptimal := pointer to the fastest function for given evaluation string

     switch(GetActionOptimized(0)){
       case kData : {fOptimal= (TFormulaPrimitive::TFuncG)&TFormula::EvalPrimitive0; break;}
       case kUnary : {fOptimal= (TFormulaPrimitive::TFuncG)&TFormula::EvalPrimitive1; break;}
       case kBinary : {fOptimal= (TFormulaPrimitive::TFuncG)&TFormula::EvalPrimitive2; break;}
       case kThree : {fOptimal= (TFormulaPrimitive::TFuncG)&TFormula::EvalPrimitive3; break;}
       case kFDM : {fOptimal= (TFormulaPrimitive::TFuncG)&TFormula::EvalPrimitive4; break;}
     }

  2. ex.
     • fOptimal = TFormula::EvalPrimitive0 - if it return only variable, constant or parameter
     • = TFormula::EvalPrimitive1 - if only one unary operation
     • = TFormula::EvalPrimitive2 - if only one binary operation

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.

SaveAs()

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

virtualinherited

• 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.
