70 \class QSaveFile-
71 \inmodule QtCore-
72 \brief The QSaveFile class provides an interface for safely writing to files.-
73-
74 \ingroup io-
75-
76 \reentrant-
77-
78 \since 5.1-
79-
80 QSaveFile is an I/O device for writing text and binary files, without losing-
81 existing data if the writing operation fails.-
82-
83 While writing, the contents will be written to a temporary file, and if-
84 no error happened, commit() will move it to the final file. This ensures that-
85 no data at the final file is lost in case an error happens while writing,-
86 and no partially-written file is ever present at the final location. Always-
87 use QSaveFile when saving entire documents to disk.-
88-
89 QSaveFile automatically detects errors while writing, such as the full partition-
90 situation, where write() cannot write all the bytes. It will remember that-
91 an error happened, and will discard the temporary file in commit().-
92-
93 Much like with QFile, the file is opened with open(). Data is usually read-
94 and written using QDataStream or QTextStream, but you can also call the-
95 QIODevice-inherited functions read(), readLine(), readAll(), write().-
96-
97 Unlike QFile, calling close() is not allowed. commit() replaces it. If commit()-
98 was not called and the QSaveFile instance is destroyed, the temporary file is-
99 discarded.-
100-
101 To abort saving due to an application error, call cancelWriting(), so that-
102 even a call to commit() later on will not save.-

362 Allows writing over the existing file if necessary.-
363-
364 QSaveFile creates a temporary file in the same directory as the final-
365 file and atomically renames it. However this is not possible if the-
366 directory permissions do not allow creating new files.-
367 In order to preserve atomicity guarantees, open() fails when it-
368 cannot create the temporary file.-
369-
370 In order to allow users to edit files with write permissions in a-
371 directory with restricted permissions, call setDirectWriteFallback() with-
372 \a enabled set to true, and the following calls to open() will fallback to-
373 opening the existing file directly and writing into it, without the use of-
374 a temporary file.-
375 This does not have atomicity guarantees, i.e. an application crash or-
376 for instance a power failure could lead to a partially-written file on disk.-
377 It also means cancelWriting() has no effect, in such a case.-
378-
379 Typically, to save documents edited by the user, call setDirectWriteFallback(true),-
380 and to save application internal files (configuration files, data files, ...), keep-
381 the default setting which ensures atomicity.-
