\class QSaveFile
|
||||||
|
\brief The QSaveFile class provides an interface for safely writing to files.
|
||||||
|
|
||||||
|
\ingroup io
|
||||||
|
|
||||||
|
\reentrant
|
||||||
|
|
||||||
|
QSaveFile is an I/O device for writing text and binary files, without losing
|
||||||
|
existing data if the writing operation fails.
|
||||||
|
|
||||||
|
While writing, the contents will be written to a temporary file, and if
|
||||||
|
no error happened, commit() will move it to the final file. This ensures that
|
||||||
|
no data at the final file is lost in case an error happens while writing,
|
||||||
|
and no partially-written file is ever present at the final location. Always
|
||||||
|
use QSaveFile when saving entire documents to disk.
|
||||||
|
|
||||||
|
QSaveFile automatically detects errors while writing, such as the full partition
|
||||||
|
situation, where write() cannot write all the bytes. It will remember that
|
||||||
|
an error happened, and will discard the temporary file in commit().
|
||||||
|
|
||||||
|
Much like with QFile, the file is opened with open(). Data is usually read
|
||||||
|
and written using QDataStream or QTextStream, but you can also call the
|
||||||
|
QIODevice-inherited functions read(), readLine(), readAll(), write().
|
||||||
|
|
||||||
|
Unlike QFile, calling close() is not allowed. commit() replaces it. If commit()
|
||||||
|
was not called and the QSaveFile instance is destroyed, the temporary file is
|
||||||
|
discarded.
