Note that the compression settings may be changed at any time. The new compression settings will only apply to branches created or attached after the setting is changed and other objects written after the setting is changed.

One can detect this situation with a code like: TFile f "file. If something wrong is detected, an automatic Recovery is performed. In this case, the file is scanned sequentially reading all logical blocks and attempting to rebuild a correct directory see TFile :: Recover.

One can disable the automatic recovery procedure when reading one or more files by setting the environment variable "TFile.

Recover: 0" in the system. TFile implementations providing asynchronous open functionality need to override this method to run the appropriate checks before calling this standard initialization part.

Calling TFile :: Close "R" might be necessary in case one reads a long list of files having TRef , writing some of the referenced objects or TRef to a new file.

If the TRef or referenced objects of the file being closed will not be referenced again, it is possible to minimize the size of the TProcessID data structures in memory by forcing a delete of the unused TProcessID.

Note that if ' cd ' has been called on a TDirectory that does not belong to a file, gFile will be unchanged and still points to the file of the previous current directory that was a file.

Loop on all objects memory or file and all subdirectories. Return kTRUE in case of error. The file output buffer contains only the FREE data record.

The best buffer size is estimated based on the current mean value and standard deviation of all objects written so far to this file.

Maxbytes bytes are read into buf the function reads nread bytes where nread is the minimum of maxbytes and the number of bytes before the end of file.

The function returns nread. Returns -1 in case the file could not be stat'ed. The function returns a TList. It is the user'responsability to delete the list created by this function.

Using the list, one can access additional information,eg: TFile f "myfile. Indentation is used to identify the file tree. Subdirectories are listed first, then objects in memory, then objects on the file.

The list of free segments is in the fFree linked list. Returns kTRUE in case of failure. This is the basic low level read operation. Returns 0 if the requested block is not in the cache, 1 in case read via cache was successful, 2 in case read via cache failed.

Every file has a linked list fFree of free segments. This linked list has been written on the file via WriteFree as a single data record.

If the object is not already entered in the gROOT list, it is added. 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: TFile f "myfile. You can test if the file has been recovered with if f.

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. The method returns 0 in case the mode was successfully modified, 1 in case the mode did not change was already as requested or wrong input arguments and -1 in case of failure, in which case the file cannot be used anymore.

The current directory gFile is changed to this file. Pos it either kBeg , kCur or kEnd. There is a utility function to help to set the value of the argument.

If set to default kDisconnect , the contents of the cache will be flushed when it is removed from the file, and it will disconnect the cache object from the file.

In almost all cases, this is what you want. If you want to disconnect the cache temporarily from this tree and re-attach later to the same fil, you can set action to kDoNotDisconnect.

This will allow things like prefetching to continue in the background while it is no longer the default cache for the TTree. Except for a few expert use cases, kDisconnect is likely the correct setting.

If file is null the existing write cache is deleted. 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. This is the basic low level write operation.

Returns 0 if cache is not active, 1 in case write via cache was successful, 2 in case write via cache failed. The code generated includes: dirnameProjectHeaders.

If dirname already exist, an error message is printed and the function returns. Existing classes with the same name are replaced by the new definition.

If the directory dirname doest not exist, same effect as "new". The name of the PAR file is basename dirname , with extension '.

Example: file. Called by MakeProject when option 'par' is given. Return 0 on success, -1 on error. C under 'proofinf' for PAR package 'pack'.

The key with name holding the list of TStreamerInfo objects is read. The corresponding TClass objects are updated. Note that this function is not called if the static member fgReadInfo is falsse.

It may be interesting to set fgReadInfo to false to speedup the file opening time or in case libraries containing classes referenced by the file have not yet been loaded.

ReadStreamerInfo ;. See class TStreamerInfo. The file will be downloaded to the cache and opened from there.

If the download fails, it will be opened remotely. The file will be downloaded to the directory specified by SetCacheFileDir.

The returned type of TFile depends on the file name specified by 'url'. If 'url' is a ' ' -separated list of file URLs, the 'URLs' are tried sequentially in the specified order until a successful open.

If that is the case the file will be opened via a normal TFile. The netopt argument is only used by TNetFile. For the meaning of the options and other arguments see the constructors of the individual file classes.

In case of error returns 0. The request will be processed asynchronously. This call never blocks and it is provided to allow parallel submission of file opening operations expected to take a long time.

To be effective, the underlying TFile implementation must be able to support asynchronous open functionality. Currently, only TXNetFile supports it.

Returns the associated TFile , transferring ownership of the handle to the TFile instance. All arguments like in POSIX lseek except that the offset and return value are of a type which are able to handle 64 bit file systems.

The function returns 0 in case of success and 1 if the file could not be stat'ed. Does not take into account what might still be in the write caches.

With the clenupinterval you can specify the minimum amount of time after the previous cleanup before the cleanup operation is repeated in the cache directory.

Returns previous timeout value. Returns previous value of flag. When true we check before opening the file if it is staged, if not, the open fails.

The check is implementation dependent and may need to be overload by each TFile implememtation relying on this check.

The default implementation checks the file name only. Returns 0 is the information is not yet available. Actually we tell the kernel which blocks we are going to read so it can start loading these blocks in the buffer cache.

But specific TFile implementations may need to change it. TDirectory:: AddDirectoryStatus. TObject:: ClassName const. TDirectory:: CurrentDirectory.

If dirname already exist, an error message is printed and the function returns. If dirname already exist, all existing files in dirname are deleted before creating the new files.

Existing classes with the same name are replaced by the new definition. If the directory dirname doest not exist, same effect as "new".

The name of the PAR file is basename dirname , with extension '. Example: file. Create makefile at 'filemake' for PAR package 'pack'.
