\subsection{Detailed Description}
A file inside ZIP archive. 

This is the most interesting class. Not only it provides C++ interface to the ZIP/UNZIP package, but also integrates it with Qt by subclassing QIODevice. This makes possible to access files inside ZIP archive using QTextStream or QDataStream, for example. Actually, this is the main purpose of the whole QuaZIP library.

You can either use existing \doxyref{QuaZip}{p.}{classQuaZip} instance to create instance of this class or pass ZIP archive file name to this class, in which case it will create internal \doxyref{QuaZip}{p.}{classQuaZip} object. See constructors' descriptions for details. Writing is only possible with the existing instance.

Note that due to the underlying library's limitation it is not possible to use multiple \doxyref{QuaZipFile}{p.}{classQuaZipFile} instances to open several files in the same archive at the same time. If you need to write to multiple files in parallel, then you should write to temporary files first, then pack them all at once when you have finished writing. If you need to read multiple files inside the same archive in parallel, you should extract them all into a temporary directory first.\subsection{Sequential or random-\/access?}\label{classQuaZipFile_quazipfile-sequential}
At the first thought, \doxyref{QuaZipFile}{p.}{classQuaZipFile} has fixed size, the start and the end and should be therefore considered random-\/access device. But there is one major obstacle to making it random-\/access: ZIP/UNZIP API does not support seek() operation and the only way to implement it is through reopening the file and re-\/reading to the required position, but this is prohibitively slow.

Therefore, \doxyref{QuaZipFile}{p.}{classQuaZipFile} is considered to be a sequential device. This has advantage of availability of the ungetChar() operation (QIODevice does not implement it properly for non-\/sequential devices unless they support seek()). Disadvantage is a somewhat strange behaviour of the \doxyref{size()}{p.}{classQuaZipFile_ad1a17cc690a01c3edfb82984c3a4c8f0} and \doxyref{pos()}{p.}{classQuaZipFile_a90fd55dab83eca7f95df50b2c41b7f22} functions. This should be kept in mind while using this class.

Constructs a \doxyref{QuaZipFile}{p.}{classQuaZipFile} instance. 

{\itshape parent\/} argument specifies this object's parent object.

{\itshape zip\/} is the pointer to the existing \doxyref{QuaZip}{p.}{classQuaZip} object. This \doxyref{QuaZipFile}{p.}{classQuaZipFile} object then can be used to read current file in the {\itshape zip\/} or to write to the file inside it.

\begin{DoxyWarning}{Warning}
Using this constructor for reading current file can be tricky. Let's take the following example: 
\begin{DoxyCode}
 QuaZip zip("archive.zip");
 zip.open(QuaZip::mdUnzip);
 zip.setCurrentFile("file-in-archive");
 QuaZipFile file(&zip);
 file.open(QIODevice::ReadOnly);
 // ok, now we can read from the file
 file.read(somewhere, some);
 zip.setCurrentFile("another-file-in-archive"); // oops...
 QuaZipFile anotherFile(&zip);
 anotherFile.open(QIODevice::ReadOnly);
 anotherFile.read(somewhere, some); // this is still ok...
 file.read(somewhere, some); // and this is NOT
\end{DoxyCode}
 So, what exactly happens here? When we change current file in the {\ttfamily zip} archive, {\ttfamily file} that references it becomes invalid (actually, as far as I understand ZIP/UNZIP sources, it becomes closed, but \doxyref{QuaZipFile}{p.}{classQuaZipFile} has no means to detect it).
\end{DoxyWarning}
Summary: do not close {\ttfamily zip} object or change its current file as long as \doxyref{QuaZipFile}{p.}{classQuaZipFile} is open. Even better -\/ use another constructors which create internal \doxyref{QuaZip}{p.}{classQuaZip} instances, one per object, and therefore do not cause unnecessary trouble. This constructor may be useful, though, if you already have a \doxyref{QuaZip}{p.}{classQuaZip} instance and do not want to access several files at once. Good example: 
\begin{DoxyCode}
 QuaZip zip("archive.zip");
 zip.open(QuaZip::mdUnzip);
 // first, we need some information about archive itself
 QByteArray comment=zip.getComment();
 // and now we are going to access files inside it
 QuaZipFile file(&zip);
 for(bool more=zip.goToFirstFile(); more; more=zip.goToNextFile()) {
   file.open(QIODevice::ReadOnly);
   // do something cool with file here
   file.close(); // do not forget to close!
 }
 zip.close();

Returns the actual file name in the archive. 

This is {\itshape not\/} a ZIP archive file name, but a name of file inside archive. It is not necessary the same name that you have passed to the \doxyref{QuaZipFile(const QString\&,const QString\&,QuaZip::CaseSensitivity,QObject$\ast$)}{p.}{classQuaZipFile_ac6e883b5a5d3a58c9c56eb497dd91220}, \doxyref{setFileName()}{p.}{classQuaZipFile_a3732ca7704379d457b6a27db8837de95} or \doxyref{QuaZip::setCurrentFile()}{p.}{classQuaZip_a6c657bfcfccb59d728e0da24c677d899} -\/ this is the real file name inside archive, so it may differ in case if the file name search was case-\/insensitive.

Equivalent to calling getCurrentFileName() on the associated \doxyref{QuaZip}{p.}{classQuaZip} object. Returns null string if there is no associated \doxyref{QuaZip}{p.}{classQuaZip} object or if it does not have a current file yet. And this is the case if you called \doxyref{setFileName()}{p.}{classQuaZipFile_a3732ca7704379d457b6a27db8837de95} but did not open the file yet. So this is perfectly fine: 
\begin{DoxyCode}
 QuaZipFile file("somezip.zip");
 file.setFileName("somefile");
 QString name=file.getName(); // name=="somefile"
 QString actual=file.getActualFileName(); // actual is null string
 file.open(QIODevice::ReadOnly);
 QString actual=file.getActualFileName(); // actual can be "SoMeFiLe" on Windows
\end{DoxyCode}

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Argument {\itshape password\/} specifies a password to decrypt the file.

An integers pointed by {\itshape method\/} and {\itshape level\/} will receive codes of the compression method and level used. See unzip.h.

If raw is {\ttfamily true} then no decompression is performed.

{\itshape method\/} should not be {\ttfamily NULL}. {\itshape level\/} can be {\ttfamily NULL} if you don't want to know the compression level.

Opens a file for writing. 

{\itshape info\/} argument specifies information about file. It should at least specify a correct file name. Also, it is a good idea to specify correct timestamp (by default, current time will be used). See \doxyref{QuaZipNewInfo}{p.}{structQuaZipNewInfo}.

The {\itshape password\/} argument specifies the password for crypting. Pass NULL if you don't need any crypting. The {\itshape crc\/} argument was supposed to be used for crypting too, but then it turned out that it's false information, so you need to set it to 0 unless you want to use the raw mode (see below).

Arguments {\itshape method\/} and {\itshape level\/} specify compression method and level. The only method supported is Z\_\-DEFLATED, but you may also specify 0 for no compression. If all of the files in the archive use both method 0 and either level 0 is explicitly specified or data descriptor writing is disabled with \doxyref{QuaZip::setDataDescriptorWritingEnabled()}{p.}{classQuaZip_a6c23a12af88f7ea5edd4f9c0a24b9453}, then the resulting archive is supposed to be compatible with the 1.0 ZIP format version, should you need that. Except for this, {\itshape level\/} has no other effects with method 0.

If {\itshape raw\/} is {\ttfamily true}, no compression is performed. In this case, {\itshape crc\/} and uncompressedSize field of the {\itshape info\/} are required.

Arguments {\itshape windowBits\/}, {\itshape memLevel\/}, {\itshape strategy\/} provide zlib algorithms tuning. See deflateInit2() in zlib.

Returns current position in the file. 

Implementation of the QIODevice::pos(). When reading, this function is a wrapper to the ZIP/UNZIP unztell(), therefore it is unable to keep track of the ungetChar() calls (which is non-\/virtual and therefore is dangerous to reimplement). So if you are using ungetChar() feature of the QIODevice, this function reports incorrect value until you get back characters which you ungot.

When writing, \doxyref{pos()}{p.}{classQuaZipFile_a90fd55dab83eca7f95df50b2c41b7f22} returns number of bytes already written (uncompressed unless you use raw mode).

\begin{DoxyNote}{Note}
Although \doxyref{QuaZipFile is a sequential device}{p.}{classQuaZipFile_quazipfile-sequential} and therefore \doxyref{pos()}{p.}{classQuaZipFile_a90fd55dab83eca7f95df50b2c41b7f22} should always return zero, it does not, because it would be misguiding. Keep this in mind.
\end{DoxyNote}
This function returns -\/1 if the file or archive is not open.

Error code returned by \doxyref{getZipError()}{p.}{classQuaZipFile_a26d2ee56aad947193b73052f80597ef0} is not affected by this function call.

Returns {\ttfamily true} if the end of file was reached. 

This function returns {\ttfamily false} in the case of error. This means that you called this function on either not open file, or a file in the not open archive or even on a \doxyref{QuaZipFile}{p.}{classQuaZipFile} instance that does not even have \doxyref{QuaZip}{p.}{classQuaZip} instance associated. Do not do that because there is no means to determine whether {\ttfamily false} is returned because of error or because end of file was reached. Well, on the other side you may interpret {\ttfamily false} return value as \char`\"{}there is no file open to check for end of file and there is
 no end of file therefore\char`\"{}.

When writing, this function always returns {\ttfamily true} (because you are always writing to the end of file).
