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.

Disconnect() [3/3]

Bool_t TQObject::Disconnect ( TQObject * sender, const char * signal = nullptr, void * receiver = nullptr, const char * slot = nullptr )

staticinherited

Disconnects signal in object sender from slot_method in object receiver.

For objects derived from TQObject signal-slot connection is removed when either of the objects involved are destroyed.

Disconnect() is typically used in three ways, as the following examples shows:

• Disconnect everything connected to an object's signals:

  Disconnect(myObject);

• Disconnect everything connected to a signal:

  Disconnect(myObject, "mySignal()");

• Disconnect a specific receiver:

  Disconnect(myObject, 0, myReceiver, 0);

0 may be used as a wildcard in three of the four arguments, meaning "any signal", "any receiving object" or "any slot in the receiving object", respectively.

The sender has no default and may never be 0 (you cannot disconnect signals from more than one object).

If signal is 0, it disconnects receiver and slot_method from any signal. If not, only the specified signal is disconnected.

If receiver is 0, it disconnects anything connected to signal. If not, slots in objects other than receiver are not disconnected

If slot_method is 0, it disconnects anything that is connected to receiver. If not, only slots named slot_method will be disconnected, and all other slots are left alone. The slot_method must be 0 if receiver is left out, so you cannot disconnect a specifically-named slot on all objects.

template<typename T>

void TQObject::Emit ( const char * signal, const T & arg )

inlineinherited

Activate signal with single parameter.

Example:

theButton->Emit("Progress(Long64_t)",processed)

If we call Emit with an array of the parameters, they should be converted to Longptr_t type. Example:

TQObject *processor; // data processor
TH1F     *hist;      // filled with processor results
 
processor->Connect("Evaluated(Float_t,Float_t)",
                   "TH1F",hist,"Fill12(Axis_t,Axis_t)");
 
Longptr_t args[2];
args[0] = (Longptr_t)processor->GetValue(1);
args[1] = (Longptr_t)processor->GetValue(2);
 
processor->Emit("Evaluated(Float_t,Float_t)",args);

Hash()

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.

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)

Merge()

Long64_t TSeqCollection::Merge ( TCollection * list )

inherited

Merge this collection with all collections coming in the input list.

The input list must contain other collections of objects compatible with the ones in this collection and ordered in the same manner. For example, if this collection contains a TH1 object and a tree, all collections in the input list have to contain a histogram and a tree. In case the list contains collections, the objects in the input lists must also be collections with the same structure and number of objects. If some objects inside the collection are instances of a class that do not have a Merge function (like TObjString), rather than merging, a copy of each instance (via a call to Clone) is appended to the output.

Example

  this                          list
____________                  ---------------------|
| A (TH1F) |  __________      | L1 (TSeqCollection)|- [A1, B1(C1,D1,E1)]

Print() [4/4]

void TCollection::Print ( Option_t * option = "" ) const

overridevirtualinherited

Default print for collections, calls Print(option, 1).

This will print the collection header and Print() methods of all the collection entries.

If you want to override Print() for a collection class, first see if you can accomplish it by overriding the following protected methods:

void        PrintCollectionHeader(Option_t* option) const;
const char* GetCollectionEntryName(TObject* entry) const;
void        PrintCollectionEntry(TObject* entry, Option_t* option, Int_t recurse) const;

Otherwise override the Print(Option_t *option, Int_t) variant. Remember to declare:

using TCollection::Print;

somewhere close to the method declaration.

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.
