\subsection{Detailed Description}
ZIP archive. 

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 \doxyref{QuaZipFile}{p.}{classQuaZipFile} class. But see \doxyref{QuaZipFile::QuaZipFile(QuaZip$\ast$, QObject$\ast$)}{p.}{classQuaZipFile_a54e944a6b3d27030f64c8f30d2cc33bb} 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 \doxyref{open()}{p.}{classQuaZip_abfa4e6018b2964a3d10a4c54e5ab3962} 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 \doxyref{getUnzFile()}{p.}{classQuaZip_a3b78a652f296ff4a678a791e8294e642} and \doxyref{getZipFile()}{p.}{classQuaZip_a425043a4d7cc31e2fe2bba73d954f15c} 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 {\ttfamily IBM866} encoding instead of {\ttfamily 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?

Opens ZIP file. 

Argument {\itshape mode\/} specifies open mode of the ZIP archive. See Mode for details. Note that there is zipOpen2() function in the ZIP/UNZIP API which accepts {\itshape globalcomment\/} argument, but it does not use it anywhere, so this \doxyref{open()}{p.}{classQuaZip_abfa4e6018b2964a3d10a4c54e5ab3962} function does not have this argument. See \doxyref{setComment()}{p.}{classQuaZip_a1b5d936a203859340574d5908ffa2222} if you need to set global comment.

If the ZIP file is accessed via explicitly set {\bf 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.

\begin{DoxyReturn}{Returns}
{\ttfamily true} if successful, {\ttfamily false} otherwise.
\end{DoxyReturn}
\begin{DoxyNote}{Note}
ZIP/UNZIP API open calls do not return error code -\/ they just return {\ttfamily NULL} indicating an error. But to make things easier, \doxyref{quazip.h}{p.}{quazip_8h_source} header defines additional error code {\ttfamily UNZ\_\-ERROROPEN} and \doxyref{getZipError()}{p.}{classQuaZip_a28b91a6282ddd9382c96a069572c6fb4} will return it if the open call of the ZIP/UNZIP API returns {\ttfamily NULL}.
\end{DoxyNote}
Argument {\itshape 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 \doxyref{QuaZip}{p.}{classQuaZip} is different from the original package. The file path argument was changed to be of type {\ttfamily voidpf}, and \doxyref{QuaZip}{p.}{classQuaZip} passes a {\bf QIODevice} pointer there. This {\bf QIODevice} is either set explicitly via \doxyref{setIoDevice()}{p.}{classQuaZip_a64642948b6531ee54f5522f29e388cc6} or the \doxyref{QuaZip(QIODevice$\ast$)}{p.}{classQuaZip_ae52ebadd5ce64cdb49d7e198904b0b8c} constructor, or it is created internally when opening the archive by its file name. The default API (qioapi.cpp) just delegates everything to the {\bf QIODevice} API. Not only this allows to use a {\bf 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).

\begin{DoxyNote}{Note}
If the zip64 support is needed, the ioApi argument {\itshape must\/} be NULL because due to the backwards compatibility issues it can be used to provide a 32-\/bit API only.

If the \doxyref{no-\/auto-\/close}{p.}{classQuaZip_a54bfc924762774ccf9f99be075ba7b0e} feature is used, then the {\itshape ioApi\/} argument {\itshape 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).
\end{DoxyNote}
In short: just forget about the {\itshape ioApi\/} argument and you'll be fine.

Closes ZIP file. 

Call \doxyref{getZipError()}{p.}{classQuaZip_a28b91a6282ddd9382c96a069572c6fb4} to determine if the close was successful.

If the file was opened by name, then the underlying {\bf QIODevice} is closed and deleted.

If the underlying {\bf QIODevice} was set explicitly using \doxyref{setIoDevice()}{p.}{classQuaZip_a64642948b6531ee54f5522f29e388cc6} or the appropriate constructor, then it is closed if the auto-\/close flag is set (which it is by default). Call \doxyref{setAutoClose()}{p.}{classQuaZip_a54bfc924762774ccf9f99be075ba7b0e} to clear the auto-\/close flag if this behavior is undesirable.

Since {\bf Qt} 5.1, the {\bf QSaveFile} was introduced. It breaks the {\bf QIODevice} API by making \doxyref{close()}{p.}{classQuaZip_a7a4323b73e12f3b4470109f200728f9f} private and crashing the application if it is called from the base class where it is public. It is an excellent example of poor design that illustrates why you should never ever break an is-\/a relationship between the base class and a subclass. QuaZIP works around this bug by checking if the {\bf QIODevice} is an instance of {\bf QSaveFile}, using qobject\_\-cast$<$$>$, and if it is, calls {\bf QSaveFile::commit()} instead of \doxyref{close()}{p.}{classQuaZip_a7a4323b73e12f3b4470109f200728f9f}. It is a really ugly hack, but at least it makes your programs work instead of crashing. Note that if the auto-\/close flag is cleared, then this is a non-\/issue, and commit() isn't called.

This is not a wrapper to unzLocateFile() function. That is because I had to implement locale-\/specific case-\/insensitive comparison.

Here are the differences from the original implementation:


\begin{DoxyItemize}
\item If the file was not found, error code is {\ttfamily UNZ\_\-OK}, not {\ttfamily UNZ\_\-END\_\-OF\_\-LIST\_\-OF\_\-FILE} (see also \doxyref{goToNextFile()}{p.}{classQuaZip_aee6779b6cd338420c2e8c5655fa8ba97}).
\item If this function fails, it unsets the current file rather than resetting it back to what it was before the call.
\end{DoxyItemize}

If {\itshape fileName\/} is null string then this function unsets the current file and return {\ttfamily true}. Note that you should close the file first if it is open! See \doxyref{QuaZipFile::QuaZipFile(QuaZip$\ast$,QObject$\ast$)}{p.}{classQuaZipFile_a54e944a6b3d27030f64c8f30d2cc33bb} for the details.

Changes the data descriptor writing mode. 

According to the ZIP format specification, a file inside archive may have a data descriptor immediately following the file data. This is reflected by a special flag in the local file header and in the central directory. By default, QuaZIP sets this flag and writes the data descriptor unless both method and level were set to 0, in which case it operates in 1.0-\/compatible mode and never writes data descriptors.

By setting this flag to false, it is possible to disable data descriptor writing, thus increasing compatibility with archive readers that don't understand this feature of the ZIP file format.

Setting this flag affects all the \doxyref{QuaZipFile}{p.}{classQuaZipFile} instances that are opened after this flag is set.

The data descriptor writing mode is enabled by default.

Note that if the ZIP archive is written into a {\bf QIODevice} for which {\bf QIODevice::isSequential()} returns {\ttfamily true}, then the data descriptor is mandatory and will be written even if this flag is set to false.

This function doesn't support zip64, but will still work with zip64 archives, converting results using \doxyref{QuaZipFileInfo64::toQuaZipFileInfo()}{p.}{structQuaZipFileInfo64_ada29945c7ee4c9df6fbe95864793aade}. If all file sizes are below 4 GB, it will work just fine.

Enables the zip64 mode. 


\begin{DoxyParams}{Parameters}
{\em zip64} & If {\ttfamily true}, the zip64 mode is enabled, disabled otherwise.\\
\hline
\end{DoxyParams}
Once this is enabled, all new files (until the mode is disabled again) will be created in the zip64 mode, thus enabling the ability to write files larger than 4 GB. By default, the zip64 mode is off due to compatibility reasons.

Note that this does not affect the ability to read zip64 archives in any way.

Sets or unsets the auto-\/close flag. 

By default, QuaZIP opens the underlying {\bf QIODevice} when \doxyref{open()}{p.}{classQuaZip_abfa4e6018b2964a3d10a4c54e5ab3962} is called, and closes it when \doxyref{close()}{p.}{classQuaZip_a7a4323b73e12f3b4470109f200728f9f} is called. In some cases, when the device is set explicitly using \doxyref{setIoDevice()}{p.}{classQuaZip_a64642948b6531ee54f5522f29e388cc6}, 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 \doxyref{open()}{p.}{classQuaZip_abfa4e6018b2964a3d10a4c54e5ab3962} call if an error is encountered after the device is opened.

If the device was not set explicitly, but rather the \doxyref{setZipName()}{p.}{classQuaZip_aa80b661de1262af905d1677dbcb008cc} 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.

Sets the default file name codec to use. 

The default codec is used by the constructors, so calling this function won't affect the \doxyref{QuaZip}{p.}{classQuaZip} instances already created at that moment.

The codec specified here can be overriden by calling \doxyref{setFileNameCodec()}{p.}{classQuaZip_a339010b5566704ba3c9cafbfe848d8fb}. If neither function is called, {\bf QTextCodec::codecForLocale()} will be used to decode or encode file names. Use this function with caution if the application uses other libraries that depend on QuaZIP. Those libraries can either call this function by themselves, thus overriding your setting or can rely on the default encoding, thus failing mysteriously if you change it. For these reasons, it isn't recommended to use this function if you are developing a library, not an application. Instead, ask your library users to call it in case they need specific encoding.

In most cases, using \doxyref{setFileNameCodec()}{p.}{classQuaZip_a339010b5566704ba3c9cafbfe848d8fb} instead is the right choice. However, if you depend on third-\/party code that uses QuaZIP, then the reasons stated above can actually become a reason to use this function in case the third-\/party code in question fails because it doesn't understand the encoding you need and doesn't provide a way to specify it. This applies to the \doxyref{JlCompress}{p.}{classJlCompress} class as well, as it was contributed and doesn't support explicit encoding parameters.

In short: use \doxyref{setFileNameCodec()}{p.}{classQuaZip_a339010b5566704ba3c9cafbfe848d8fb} when you can, resort to \doxyref{setDefaultFileNameCodec()}{p.}{classQuaZip_a317f5db89d84a80417338a3ab89770da} when you don't have access to the \doxyref{QuaZip}{p.}{classQuaZip} instance.
