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.

AddPixmap()

Int_t TVirtualX::AddPixmap ( ULongptr_t pixid, UInt_t w, UInt_t h )

virtual

Registers a pixmap created by TGLManager as a ROOT pixmap.

Parameters

[in]	pixid	pixmap identifier
[in]	w,h	the width and height, which define the pixmap size

Reimplemented in TGCocoa, TGWin32, and TGX11.

Definition at line 772 of file TVirtualX.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.

AddWindow()

Int_t TVirtualX::AddWindow ( ULongptr_t qwid, UInt_t w, UInt_t h )

virtual

Registers a window created by Qt as a ROOT window.

Parameters

[in]	qwid	window identifier
[in]	w,h	the width and height, which define the window size

Reimplemented in TGCocoa, TGWin32, TGWin32VirtualXProxy, and TGX11.

Definition at line 761 of file TVirtualX.cxx.

AllocColor()

Bool_t TVirtualX::AllocColor ( Colormap_t cmap, ColorStruct_t & color )

virtual

Allocates a read-only colormap entry corresponding to the closest RGB value supported by the hardware.

If no cell could be allocated it returns kFALSE, otherwise kTRUE.

The pixel value is set to default. Let system think we could allocate color.

Parameters

[in]	cmap	the colormap
[in]	color	specifies and returns the values actually used in the cmap

Reimplemented in TGCocoa, TGWin32, TGWin32VirtualXProxy, and TGX11.

CheckedHash()

(*) 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.

Error in <ROOT::Internal::TCheckHashRecursiveRemoveConsistency::CheckRecursiveRemove>: The class SomeName overrides
TObject::Hash but does not call TROOT::RecursiveRemove in its destructor.

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)

KeysymToKeycode()

Int_t TVirtualX::KeysymToKeycode ( UInt_t keysym )

virtual

Converts the "keysym" to the appropriate keycode.

For example, keysym is a letter and keycode is the matching keyboard key (which is dependent on the current keyboard mapping). If the specified "keysym" is not defined for any keycode, returns zero.

ListFonts()

char ** TVirtualX::ListFonts ( const char * fontname, Int_t max, Int_t & count )

virtual

Returns list of font names matching fontname regexp, like "-*-times-*".

The pattern string can contain any characters, but each asterisk (*) is a wildcard for any number of characters, and each question mark (?) is a wildcard for a single character. If the pattern string is not in the Host Portable Character Encoding, the result is implementation dependent. Use of uppercase or lowercase does not matter. Each returned string is null-terminated.

Parameters

[in]	fontname	specifies the null-terminated pattern string that can contain wildcard characters
[in]	max	specifies the maximum number of names to be returned
[in]	count	returns the actual number of font names

Reimplemented in TGCocoa, TGWin32, TGWin32VirtualXProxy, and TGX11.

[in]	buf	returns the translated characters
[in]	buflen	the length of the buffer
[in]	keysym	returns the "keysym" computed from the event if this argument is not NULL

This method must be overridden if a class wants to paint itself.

SaveAs()

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

virtualinherited

Save this object in the file specified by filename.

• 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.
