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

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.

Activate()

void TMonitor::Activate ( TSocket * sock )

virtual

Activate a de-activated socket.

Definition at line 249 of file TMonitor.cxx.

ActivateAll()

void TMonitor::ActivateAll ( )

virtual

Activate all de-activated sockets.

Definition at line 267 of file TMonitor.cxx.

Add()

void TMonitor::Add ( TSocket * sock, Int_t interest = kRead )

virtual

Add socket to the monitor's active list.

If interest=kRead then we want to monitor the socket for read readiness, if interest=kWrite then we monitor the socket for write readiness, if interest=kRead|kWrite then we monitor both read and write readiness.

Definition at line 167 of file TMonitor.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.

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.

Connect() [1/3]

Bool_t TQObject::Connect ( const char * class_name, const char * signal, const char * cl, void * receiver, const char * slot )

staticinherited

This method allows to make a connection from any object of the same class to a single slot.

Signal and slot string must have a form: "Draw(char*, Option_t* ,Int_t)" All blanks and "const" words will be removed,

cl != 0 - class name, it can be class with or without dictionary, e.g interpreted class. Example:

TGButton *myButton;
TH2F     *myHist;
 
TQObject::Connect("TGButton", "Clicked()",
                  "TH2F", myHist, "Draw(Option_t*)");

cl == 0 - corresponds to function (interpereted or global) the name of the function is defined by the slot string, parameter receiver should be 0. Example:

TGButton *myButton;
TH2F     *myHist;
 
TQObject::Connect("TGButton", "Clicked()",
                  0, 0, "hsimple()");

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.

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)

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.
