Open or creates local XML file with name filename.
It is recommended to specify filename as "<file>.xml". The suffix ".xml" will be used by object browsers to automatically identify the file as a XML file. If the constructor fails in any way IsZombie() will return true. Use IsOpen() to check if the file is (still) open.
If option = NEW or CREATE create a new file and open it for writing, if the file already exists the file is not opened. = RECREATE create a new file, if the file already exists it will be overwritten. = 2xoo create a new file with specified xml settings for more details see TXMLSetup class = UPDATE open an existing file for writing. if no file exists, it is created. = READ open an existing file for reading.

Mark unused bytes on the file.
The list of free segments is in the fFree linked list. When an object is deleted from the file, the freed space is added into the FREE linked list (fFree). The FREE list consists of a chain of consecutive free segments on the file. At the same time, the first 4 bytes of the freed record on the file are overwritten by GAPSIZE where GAPSIZE = -(Number of bytes occupied by the record).

Generate source code necessary to access the objects stored in the file.
Generate code in directory dirname for all classes specified in argument classes If classes = "*" (default and currently the only supported value), the function generates an include file for each class in the StreamerInfo list for which a TClass object does not exist.
The code generated includes:
In the generated classes, map, multimap when the first template parameter is a class are replaced by a vector of pair. set and multiset when the tempalte parameter is a class are replaced by a vector. This is required since we do not have the code needed to order and/or compare the object of the classes. This is a quick explanation of the options available:
Option | Details |
---|---|
new (default) | A new directory dirname is created. If dirname already exist, an error message is printed and the function returns. |
recreate | If dirname does not exist, it is created (like in "new"). If dirname already exist, all existing files in dirname are deleted before creating the new files. |
update | New classes are added to the existing directory. Existing classes with the same name are replaced by the new definition. If the directory dirname doest not exist, same effect as "new". |
genreflex | Use genreflex rather than rootcint to generate the dictionary. |
par | Create a PAR file with the minimal set of code needed to read the content of the ROOT file. The name of the PAR file is basename(dirname), with extension '.par' enforced; the PAR file will be created at dirname(dirname). |
If, in addition to one of the 3 above options, the option "+" is specified, the function will generate:
gSystem->load("demo/demo.so");
The following feature is not yet enabled: One can restrict the list of classes to be generated by using expressions like:
classes = "Ali*" generate code only for classes starting with Ali classes = "myClass" generate code for class MyClass only.

Attempt to recover file if not correctly closed.
The function returns the number of keys that have been recovered. If no keys can be recovered, the file will be declared Zombie by the calling function. This function is automatically called when opening a file. If the file is open in read only mode, the file is not modified. If open in update mode and the function finds something to recover, a new directory header is written to the file. When opening the file gain no message from Recover will be reported. If keys have been recovered, the file is usable and you can safely read the corresponding objects. If the file is not usable (a zombie), you can test for this case with code like:
If the file has been recovered, the bit kRecovered is set in the TFile object in memory. You can test if the file has been recovered with
if (f.TestBit(TFile::kRecovered)) {... the file has been recovered}
When writing TTrees to a file, it is important to save the Tree header at regular intervals (see TTree::AutoSave). If a file containing a Tree is recovered, the last Tree header written to the file will be used. In this case all the entries in all the branches written before writing the header are valid entries. One can disable the automatic recovery procedure by setting
TFile.Recover 0
in the system.rootrc file.

Specifiy usage of namespaces in xml file In current implementation every instrumented class in file gets its unique namespace, which is equal to name of class and refer to root documentation page like <TAttPad xmlns:TAttPad="http://root.cern.ch/root/htmldoc/TAttPad.html" version="3"> And xml node for class member gets its name as combination of class name and member name <TAttPad:fLeftMargin v="0.100000"/> <TAttPad:fRightMargin v="0.100000"/> <TAttPad:fBottomMargin v="0.100000"/> and so on Usage of namespace increase size of xml file, but makes file more readable and allows to produce DTD in the case, when in several classes data member has same name Can be changed only for newly created file.

Change layout of objects in xml file Can be changed only for newly created file.
Currently there are two supported layouts:
TXMLSetup::kSpecialized = 2 This is default layout of the file, when xml nodes names class names and data member names are used. For instance: <TAttLine version="1"> <fLineColor v="1"> <fLineStyle v="1"> <fLineWidth v="1"> </TAttLine>
TXMLSetup::kGeneralized = 3 For this layout all nodes name does not depend from class definitions. The same class looks like <Class name="TAttLine" version="1"> <Member name="fLineColor" v="1"> <Member name="fLineStyle" v="1"> <Member name="fLineWidth" v="1"> </Member>

Write memory objects to this file.
Loop on all objects in memory (including subdirectories). A new key is created in the KEYS linked list for each object. The list of keys is then saved on the file (via WriteKeys) as a single data record. For values of opt see TObject::Write(). The directory header info is rewritten on the directory header record. The linked list of FREE segments is written. The file header is written (bytes 1->fBEGIN).
