EDeprecatedStatusBits enum name. WriteKeys override. GetClassIndex const. Online Tiger Foren als Tfile markieren. Bin von Delphi auf XE8 umgestiegen. GetArchiveOffset const. GetSeekInfo const. Was ist Boc On Line den Klassenmethoden falsch? Gerade beim Dateisystemzugriff wäre es schön wenn es "richtig" Interfaced gemacht worden wäre, sodass man das beim Testen wegmocken kann und nicht die komplette Unit überschreiben muss.

Reimplemented from TObject. 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.

Read the list of TStreamerInfo objects written to this file. The function returns a TList. It is the user's responsibility to delete the list created by this function.

Note the list, in addition to TStreamerInfo object, contains sometimes a TList named 'listOfRules' and containing the schema evolution rules related to the file's content.

This is an internal method which returns the list of streamer infos and also information about the success of the operation.

If defined, the string 'prefix' is added when testing the locality of a 'name' with network-like structure i. TFile implementations providing asynchronous open functionality need to override this method to run the appropriate checks before calling this standard initialization part.

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. In the generated classes, map, multimap when the first template parameter is a class are replaced by a vector of pair.

This is a quick explanation of the options available:. The following feature is not yet enabled: One can restrict the list of classes to be generated by using expressions like:.

Note: The combined size of the classname, name and title is truncated to characters a little more for regular keys of small files.

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

The default implementation checks the file name only. 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 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. Returns the pointer to the associated TFile , transferring ownership of the handle to the TFile instance.

Returns kTRUE in case of failure. The value pos[i] is the seek position of block i of length len[i].

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. The TProcessID with number pidf is read from this file.

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 false.

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 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.

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. This relinquishes ownership of the previous cache, so if you do not already have a pointer to the previous cache and there was a previous cache , you ought to retrieve and delete it if needed using:.

The action specifies how to behave when detaching a cache from the the TFile. 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.

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

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 ;. 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.

Interface to system close. Interface to system open. 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. 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. Returns 0 if cache is not active, 1 in case write via cache was successful, 2 in case write via cache failed.

Check if the ProcessID pidd is already in the file, if not, add it and return the index number in the local file list.

Write the list of TStreamerInfo as a single object in this file The class Streamer description for all classes written to this file is saved.

Asynchronous open request status. File type. Open timeout constants. File default Constructor. If no file exists, it is created. READ Open an existing file for reading default.

NET Used by derived remote file access classes, not a user callable option. WEB Used by derived remote http access class, not a user callable option.

One can detect this situation with a code like: TFile f "file. File destructor. Submit an asynchronous open request.

Close a file. Copy this to obj. Allows to copy this file to the dst URL. Allows to copy file from src to dst URL. Print file copy progress.

Creates key for object and converts data to buffer. Delete object namecycle. Parameters [in] namecycle Encodes the name and cycle of the objects to delete Namecycle identifies an object in the top directory of the file namecycle has the format name;cycle.

Fill Graphics Structure and Paint. Loop on all objects memory or file and all subdirectories. Draw map of objects in this file. Encode file output buffer.

The file output buffer contains only the FREE data record. Synchronize a file's in-memory and on-disk states. Flush the write cache if active.

Get status of the async open request related to 'name'. Get status of the async open request related to 'handle'. Return the best buffer size of objects on this file.

Max number of bytes to prefetch. Return the total number of bytes written so far to the file. Return a pointer to the current read cache.

Return a pointer to the current write cache. Return the file compression factor. Returns the ratio of the two. Get final URL for file being opened asynchronously.

Returns 0 is the information is not yet available. Method returning errno. Static function returning the total number of bytes read from all files.

Static function returning the total number of bytes written to all files. Does not take into account what might still be in the write caches.

Static function returning the total number of read calls from all files. Returns staged only flag. Returns open timeout in ms.

Static function returning the readahead buffer size. If the streamerinfos are to be read at file opening. Read the logical record header starting at a certain postion.

Parameters [in] maxbytes Bytes which are read into buf. Returns the current file size. Returns -1 in case the file could not be stat'ed.

Returns the cached list of StreamerInfos used in this file. Using the list, one can access additional information, e.

GetStreamerInfoList ;. See documentation of GetStreamerInfoList for more details. Resolve the file type as a function of the protocol field in 'name'.

Initialize a TFile object. Parameters [in] create Create a new file. List file contents. Mark unused bytes on the file.

Generate source code necessary to access the objects stored in the file. The code generated includes: dirnameProjectHeaders.

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.

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'. Called by MakeProject when option 'par' is given. Return 0 on success, -1 on error.

C under 'proofinf' for PAR package 'pack'. List the contents of a file sequentially. Return kTRUE if 'url' matches the coordinates of this file.

The caller is responsible for deleting the pointer. Waits for the completion of an asynchronous open request. Open a file for reading through the file cache.

Paint all objects in the file. Print all objects in the file. Read a buffer from the file. This is the basic low level read operation.
