/** \class QuaZip quazip.h <quazip/quazip.h>
|
|
* This class implements basic interface to the ZIP archive. It can be
|
|
* used to read table contents of the ZIP archive and retreiving
|
|
* information about the files inside it.
|
|
*
|
|
* You can also use this class to open files inside archive by passing
|
|
* pointer to the instance of this class to the constructor of the
|
|
* QuaZipFile class. But see QuaZipFile::QuaZipFile(QuaZip*, QObject*)
|
|
* for the possible pitfalls.
|
|
*
|
|
* This class is indended to provide interface to the ZIP subpackage of
|
|
* the ZIP/UNZIP package as well as to the UNZIP subpackage. But
|
|
* currently it supports only UNZIP.
|
|
*
|
|
* The use of this class is simple - just create instance using
|
|
* constructor, then set ZIP archive file name using setFile() function
|
|
* (if you did not passed the name to the constructor), then open() and
|
|
* then use different functions to work with it! Well, if you are
|
|
* paranoid, you may also wish to call close before destructing the
|
|
* instance, to check for errors on close.
|
|
*
|
|
* You may also use getUnzFile() and getZipFile() functions to get the
|
|
* ZIP archive handle and use it with ZIP/UNZIP package API directly.
|
|
*
|
|
* This class supports localized file names inside ZIP archive, but you
|
|
* have to set up proper codec with setCodec() function. By default,
|
|
* locale codec will be used, which is probably ok for UNIX systems, but
|
|
* will almost certainly fail with ZIP archives created in Windows. This
|
|
* is because Windows ZIP programs have strange habit of using DOS
|
|
* encoding for file names in ZIP archives. For example, ZIP archive
|
|
* with cyrillic names created in Windows will have file names in \c
|
|
* IBM866 encoding instead of \c WINDOWS-1251. I think that calling one
|
|
* function is not much trouble, but for true platform independency it
|
|
* would be nice to have some mechanism for file name encoding auto
|
|
* detection using locale information. Does anyone know a good way to do
|
|
* it?

|
|
* does not use it anywhere, so this open() function does not have this
|
|
* argument. See setComment() if you need to set global comment.
|
|
*
|
|
* If the ZIP file is accessed via explicitly set QIODevice, then
|
|
* this device is opened in the necessary mode. If the device was
|
|
* already opened by some other means, then QuaZIP checks if the
|
|
* open mode is compatible to the mode needed for the requested operation.
|
|
* If necessary, seeking is performed to position the device properly.
|
|
*
|
|
* \return \c true if successful, \c false otherwise.
|
|
*
|
|
* \note ZIP/UNZIP API open calls do not return error code - they
|
|
* just return \c NULL indicating an error. But to make things
|
|
* easier, quazip.h header defines additional error code \c
|
|
* UNZ_ERROROPEN and getZipError() will return it if the open call
|
|
* of the ZIP/UNZIP API returns \c NULL.
|
|
*
|
|
* Argument \a ioApi specifies IO function set for ZIP/UNZIP
|
|
* package to use. See unzip.h, zip.h and ioapi.h for details. Note
|
|
* that IO API for QuaZip is different from the original package.
|
|
* The file path argument was changed to be of type \c voidpf, and
|
|
* QuaZip passes a QIODevice pointer there. This QIODevice is either
|
|
* set explicitly via setIoDevice() or the QuaZip(QIODevice*)
|
|
* constructor, or it is created internally when opening the archive
|
|
* by its file name. The default API (qioapi.cpp) just delegates
|
|
* everything to the QIODevice API. Not only this allows to use a
|
|
* QIODevice instead of file name, but also has a nice side effect
|
|
* of raising the file size limit from 2G to 4G (in non-zip64 archives).
|
|
*
|
|
* \note If the zip64 support is needed, the ioApi argument \em must be NULL
|
|
* because due to the backwards compatibility issues it can be used to
|
|
* provide a 32-bit API only.
|
|
*
|
|
* \note If the \ref QuaZip::setAutoClose() "no-auto-close" feature is used,
|
|
* then the \a ioApi argument \em should be NULL because the old API
|
|
* doesn't support the 'fake close' operation, causing slight memory leaks
|
|
* and other possible troubles (like closing the output device in case
|
|
* when an error occurs during opening).
|
|
*
|
|
* In short: just forget about the \a ioApi argument and you'll be
|
|
* fine.

|

|

* works around this bug by checking if the QIODevice is an instance

* of QSaveFile, using qobject_cast<>, and if it is, calls
|
|
* QSaveFile::commit() instead of close(). It is a really ugly hack,

By default, QuaZIP opens the underlying QIODevice when open() is called,
|
|
and closes it when close() is called. In some cases, when the device
|
|
is set explicitly using setIoDevice(), it may be desirable to
|
|
leave the device open. If the auto-close flag is unset using this method,
|
|
then the device isn't closed automatically if it was set explicitly.
|
|
|
|
If it is needed to clear this flag, it is recommended to do so before
|
|
opening the archive because otherwise QuaZIP may close the device
|
|
during the open() call if an error is encountered after the device
|
|
is opened.
|
|
|
|
If the device was not set explicitly, but rather the setZipName() or
|
|
the appropriate constructor was used to set the ZIP file name instead,
|
|
then the auto-close flag has no effect, and the internal device
|
|
is closed nevertheless because there is no other way to close it.

* The codec specified here can be overriden by calling setFileNameCodec().
|
|
* If neither function is called, QTextCodec::codecForLocale() will be used

|
|
* the application uses other libraries that depend on QuaZIP. Those
|

|
* understand the encoding you need and doesn't provide a way to specify it.
|
|
* This applies to the JlCompress class as well, as it was contributed and
|
|
* doesn't support explicit encoding parameters.
|

|

|
* setDefaultFileNameCodec() when you don't have access to the QuaZip
