Detailed Description

A class for reading / writing (optionally compressed) tar archives.

KTar allows you to read and write tar archives, including those that are compressed using gzip, bzip2 or xz.

Constructor & Destructor Documentation

◆ KTar() [1/2]

KTar::KTar ( const QString &  filename,
const QString &  mimetype = QString() 
)
explicit

Creates an instance that operates on the given filename using the compression filter associated to given mimetype.

Parameters
filenameis a local path (e.g. "/home/weis/myfile.tgz")
mimetype"application/gzip" (before 5.85: "application/x-gzip"), "application/x-bzip", "application/x-xz", "application/zstd" (since 5.82) Do not use application/x-compressed-tar or similar - you only need to specify the compression layer ! If the mimetype is omitted, it will be determined from the filename.

Definition at line 69 of file ktar.cpp.

◆ KTar() [2/2]

KTar::KTar ( QIODevice *  dev)
explicit

Creates an instance that operates on the given device.

The device can be compressed (KCompressionDevice) or not (QFile, etc.).

Warning
Do not assume that giving a QFile here will decompress the file, in case it's compressed!
Parameters
devthe device to read from. If the source is compressed, the QIODevice must take care of decompression

Definition at line 84 of file ktar.cpp.

◆ ~KTar()

KTar::~KTar ( )
override

If the tar ball is still opened, then it will be closed automatically by the destructor.

Definition at line 169 of file ktar.cpp.

Member Function Documentation

◆ closeArchive()

bool KTar::closeArchive ( )
overrideprotectedvirtual

Closes the archive.

Called by close.

Implements KArchive.

Definition at line 602 of file ktar.cpp.

◆ createDevice()

bool KTar::createDevice ( QIODevice::OpenMode  mode)
overrideprotectedvirtual

Can be reimplemented in order to change the creation of the device (when using the fileName constructor).

By default this method uses QSaveFile when saving, and a simple QFile on reading. This method is called by open().

Reimplemented from KArchive.

Definition at line 91 of file ktar.cpp.

◆ doFinishWriting()

bool KTar::doFinishWriting ( qint64  size)
overrideprotectedvirtual

Reimplemented from KArchive.

Implements KArchive.

Definition at line 621 of file ktar.cpp.

◆ doPrepareWriting()

bool KTar::doPrepareWriting ( const QString &  name,
const QString &  user,
const QString &  group,
qint64  size,
mode_t  perm,
const QDateTime &  atime,
const QDateTime &  mtime,
const QDateTime &  ctime 
)
overrideprotectedvirtual

Reimplemented from KArchive.

Implements KArchive.

Definition at line 750 of file ktar.cpp.

◆ doWriteDir()

bool KTar::doWriteDir ( const QString &  name,
const QString &  user,
const QString &  group,
mode_t  perm,
const QDateTime &  atime,
const QDateTime &  mtime,
const QDateTime &  ctime 
)
overrideprotectedvirtual

Reimplemented from KArchive.

Implements KArchive.

Definition at line 834 of file ktar.cpp.

◆ doWriteSymLink()

bool KTar::doWriteSymLink ( const QString &  name,
const QString &  target,
const QString &  user,
const QString &  group,
mode_t  perm,
const QDateTime &  atime,
const QDateTime &  mtime,
const QDateTime &  ctime 
)
overrideprotectedvirtual

Reimplemented from KArchive.

Implements KArchive.

Definition at line 902 of file ktar.cpp.

◆ openArchive()

bool KTar::openArchive ( QIODevice::OpenMode  mode)
overrideprotectedvirtual

Opens the archive for reading.

Parses the directory listing of the archive and creates the KArchiveDirectory/KArchiveFile entries.

Parameters
modethe mode of the file

Implements KArchive.

Definition at line 369 of file ktar.cpp.

◆ setOrigFileName()

void KTar::setOrigFileName ( const QByteArray &  fileName)

Special function for setting the "original file name" in the gzip header, when writing a tar.gz file.

It appears when using in the "file" command, for instance. Should only be called if the underlying device is a KCompressionDevice!

Parameters
fileNamethe original file name
