Detailed Description

 KTarBase ()

[protected]

~ KTarBase ()

[protected virtual]

bool  open ( int mode )

[virtual]

Opens the tar file/data for reading or writing.

Parameters:
modemay be IO_ReadOnly or IO_WriteOnly

void  close ()

[virtual]

Closes the tar file/data.

bool  isOpened ()

[const]

Returns: true if the file is opened

void  writeDir ( const QString& name, const QString& user, const QString& group )

If a tar file is opened for writing then you can add new directories using this function. KTar won't write one directory twice.

void  writeFile ( const QString& name, const QString& user, const QString& group, uint size, const char* data )

If a tar file is opened for writing then you can add a new file using this function. If the file name is for example "mydir/test1" then the directory "mydir" is automatically appended first if that did not happen yet.

const KTarDirectory*  directory ()

[const]

If a tar file is opened for reading, then the contents of the file can be accessed via this function.

int  read ( char * buffer, int len )

[protected pure virtual]

Read len data into buffer - reimplemented

Returns: length read

void  write ( const char * buffer, int len )

[protected pure virtual]

Write len data from buffer - reimplemented

int  position ()

[protected pure virtual]

Returns: the current position - reimplemented

KTarDirectory *  findOrCreate ( const QString & path )

[protected]

Ensure path exists, create otherwise. This handles tar files missing directory entries, like mico-2.3.0.tar.gz :)

void  fillBuffer ( char * buffer, const char * mode, int size, char typeflag, const char * uname, const char * gname )

[protected]

Fills buffer for writing a file as required by the tar format Has to be called LAST, since it does the checksum (normally, only the name has to be filled in before)

Parameters:
modeis expected to be 6 chars long, [uname and gname 31].

KTarDirectory* m_dir
