160
161 When reading a zip from a stream that is seekable,
162 \helpref{GetNextEntry()}{wxzipinputstreamgetnextentry} returns
163 a fully populated wxZipEntry object except for
164 \helpref{wxZipEntry::GetLocalExtra()}{wxzipentrylocalextra}. GetLocalExtra()
165 becomes available when the entry is opened, either by calling
166 \helpref{wxZipInputStream::OpenEntry}{wxzipinputstreamopenentry} or by
167 making an attempt to read the entry's data.
168
169 For zips on \helpref{non-seekable}{wxarcnoseek} streams, the following
170 fields are always available when GetNextEntry() returns:
171
172 \helpref{GetDateTime}{wxarchiveentrydatetime}\\
173 \helpref{GetInternalFormat}{wxarchiveentrygetinternalformat}\\
174 \helpref{GetInternalName}{wxzipentrygetinternalname}\\
175 \helpref{GetFlags}{wxzipentrygetflags}\\
176 \helpref{GetLocalExtra}{wxzipentrylocalextra}\\

178 \helpref{GetName}{wxarchiveentryname}\\
179 \helpref{GetOffset}{wxarchiveentrygetoffset}\\
180 \helpref{IsDir}{wxarchiveentryisdir}
181
182 The following fields are also usually available when GetNextEntry()
183 returns, however, if the zip was also written to a non-seekable stream
184 the zipper is permitted to store them after the entry's data. In that
185 case they become available when the entry's data has been read to Eof(),
186 or \helpref{CloseEntry()}{wxarchiveinputstreamcloseentry} has been called.
187 {\tt (GetFlags() \& wxZIP\_SUMS\_FOLLOW) != 0} indicates that one or
188 more of these come after the data:
189
190 \helpref{GetCompressedSize}{wxzipentrygetcompressedsize}\\
191 \helpref{GetCrc}{wxzipentrygetcrc}\\
192 \helpref{GetSize}{wxarchiveentrysize}
193
194 The following are stored at the end of the zip, and become available
195 when the end of the zip has been reached, i.e. after GetNextEntry()
196 returns NULL and Eof() is true:
197
198 \helpref{GetComment}{wxzipentrycomment}\\

244
245 \membersection{wxZipEntry::GetCrc}\label{wxzipentrygetcrc}
246

255
256 \func{void}{SetExternalAttributes}{\param{wxUint32 }{attr}}
257
258 The low 8 bits are always the DOS/Windows file attributes for this entry.
259 The values of these attributes are given in the
260 enumeration {\tt wxZipAttributes}.
261
262 The remaining bits can store platform specific permission bits or
263 attributes, and their meaning depends on the value
264 of \helpref{SetSystemMadeBy()}{wxzipentrysystemmadeby}.
265 If \helpref{IsMadeByUnix()}{wxzipentryismadebyunix} is true then the
266 high 16 bits are unix mode bits.
267
268 The following other accessors access these bits:
269
270 \helpref{IsReadOnly/SetIsReadOnly}{wxarchiveentryisreadonly}\\
271 \helpref{IsDir/SetIsDir}{wxarchiveentryisdir}\\
272 \helpref{Get/SetMode}{wxzipentrymode}

278
279 \constfunc{size\_t}{GetExtraLen}{\void}
280
281 \func{void}{SetExtra}{\param{const char* }{extra}, \param{size\_t }{len}}
282
283 The extra field from the entry's central directory record.
284
285 The extra field is used to store platform or application specific
286 data. See Pkware's document 'appnote.txt' for information on its format.
287
288
289 \membersection{wxZipEntry::GetFlags}\label{wxzipentrygetflags}
290
291 \constfunc{int}{GetFlags}{\void}
292
293 Returns a combination of the bits flags in the enumeration {\tt wxZipFlags}.

295
296 \membersection{wxZipEntry::GetInternalName}\label{wxzipentrygetinternalname}
297
298 \constfunc{wxString}{GetInternalName}{\void}
299
300 Returns the entry's filename in the internal format used within the
301 archive. The name can include directory components, i.e. it can be a
302 full path.
303
304 The names of directory entries are returned without any trailing path
305 separator. This gives a canonical name that can be used in comparisons.
306
307 \func{wxString}{GetInternalName}{\param{const wxString\& }{name}, \param{wxPathFormat }{format = wxPATH\_NATIVE}, \param{bool* }{pIsDir = NULL}}
308
309 A static member that translates a filename into the internal format used
310 within the archive. If the third parameter is provided, the bool pointed
311 to is set to indicate whether the name looks like a directory name
312 (i.e. has a trailing path separator).

326
327 The extra field from the entry's local record.
328
329 The extra field is used to store platform or application specific
330 data. See Pkware's document 'appnote.txt' for information on its format.
331

334
335 \constfunc{int}{GetMethod}{\void}
336
337 \func{void}{SetMethod}{\param{int }{method}}
338
339 The compression method. The enumeration {\tt wxZipMethod} lists the
340 possible values.
341
342 The default constructor sets this to wxZIP\_METHOD\_DEFAULT,
343 which allows \helpref{wxZipOutputStream}{wxzipoutputstream} to
344 choose the method when writing the entry.
345
346
347 \membersection{wxZipEntry::Get/SetMode}\label{wxzipentrymode}
348
349 \constfunc{int}{GetMode}{\void}
350
351 If \helpref{IsMadeByUnix()}{wxzipentryismadebyunix} is true then
352 returns the unix permission bits stored in
353 \helpref{GetExternalAttributes()}{wxzipentryexternalattributes}.
354 Otherwise synthesises them from the DOS attributes.
355
356 \func{void}{SetMode}{\param{int }{mode}}
357
358 Sets the DOS attributes
359 in \helpref{GetExternalAttributes()}{wxzipentryexternalattributes}
360 to be consistent with the {\tt mode} given.
361
362 If \helpref{IsMadeByUnix()}{wxzipentryismadebyunix} is true then also
363 stores {\tt mode} in GetExternalAttributes().
364
365 Note that the default constructor
366 sets \helpref{GetSystemMadeBy()}{wxzipentrysystemmadeby} to
367 wxZIP\_SYSTEM\_MSDOS by default. So to be able to store unix
368 permissions when creating zips, call SetSystemMadeBy(wxZIP\_SYSTEM\_UNIX).
369
370
371 \membersection{wxZipEntry::SetNotifier}\label{wxzipentrynotifier}
372
373 \func{void}{SetNotifier}{\param{wxZipNotifier\& }{notifier}}
374
375 \func{void}{UnsetNotifier}{\void}
376
377 Sets the \helpref{notifier}{wxzipnotifier} for this entry.
378 Whenever the \helpref{wxZipInputStream}{wxzipinputstream} updates
379 this entry, it will then invoke the associated
380 notifier's \helpref{OnEntryUpdated}{wxzipnotifieronentryupdated}
381 method.
382
383 Setting a notifier is not usually necessary. It is used to handle
384 certain cases when modifying an zip in a pipeline (i.e. between
385 non-seekable streams).

395 \constfunc{int}{GetSystemMadeBy}{\void}
396
397 \func{void}{SetSystemMadeBy}{\param{int }{system}}
398
399 The originating file-system. The default constructor sets this to
400 wxZIP\_SYSTEM\_MSDOS. Set it to wxZIP\_SYSTEM\_UNIX in order to be
401 able to store unix permissions using \helpref{SetMode()}{wxzipentrymode}.
402

433 \section{\class{wxZipInputStream}}\label{wxzipinputstream}
434
435 Input stream for reading zip files.
436
437 \helpref{GetNextEntry()}{wxzipinputstreamgetnextentry} returns an
438 \helpref{wxZipEntry}{wxzipentry} object containing the meta-data
439 for the next entry in the zip (and gives away ownership). Reading from
440 the wxZipInputStream then returns the entry's data. Eof() becomes true
441 after an attempt has been made to read past the end of the entry's data.
442 When there are no more entries, GetNextEntry() returns NULL and sets Eof().
443
444 Note that in general zip entries are not seekable, and
445 wxZipInputStream::SeekI() always returns wxInvalidOffset.

554
555 If you need to know when a \helpref{wxZipInputStream}{wxzipinputstream}
556 updates a \helpref{wxZipEntry}{wxzipentry},
557 you can create a notifier by deriving from this abstract base class,
558 overriding \helpref{OnEntryUpdated()}{wxzipnotifieronentryupdated}.
559 An instance of your notifier class can then be assigned to wxZipEntry
560 objects, using \helpref{wxZipEntry::SetNotifier()}{wxzipentrynotifier}.
561
562 Setting a notifier is not usually necessary. It is used to handle
563 certain cases when modifying an zip in a pipeline (i.e. between
564 non-seekable streams).

602 \section{\class{wxZipOutputStream}}\label{wxzipoutputstream}
603
604 Output stream for writing zip files.
605
606 \helpref{PutNextEntry()}{wxzipoutputstreamputnextentry} is used to create
607 a new entry in the output zip, then the entry's data is written to the
608 wxZipOutputStream. Another call to PutNextEntry() closes the current
609 entry and begins the next.

634 \func{}{wxZipOutputStream}{\param{wxOutputStream\& }{stream}, \param{int }{level = -1}, \param{wxMBConv\& }{conv = wxConvLocal}}
635
636 \func{}{wxZipOutputStream}{\param{wxOutputStream*}{stream}, \param{int }{level = -1}, \param{wxMBConv\& }{conv = wxConvLocal}}
637
638 Constructor. {\tt level} is the compression level to use.
639 It can be a value between 0 and 9 or -1 to use the default value
640 which currently is equivalent to 6.
641
642 If the parent stream is passed as a pointer then the new filter stream
643 takes ownership of it. If it is passed by reference then it does not.
644
645 In a Unicode build the third parameter {\tt conv} is used to translate
646 the filename and comment fields to an 8-bit encoding. It has no effect on the
647 stream's data.

649
650 \membersection{wxZipOutputStream::\destruct{wxZipOutputStream}}\label{wxzipoutputstreamdtor}
651
652 \func{}{\destruct{wxZipOutputStream}}{\void}
653
654 The destructor calls \helpref{Close()}{wxzipoutputstreamclose} to finish
655 writing the zip if it has not been called already.
656
657
658 \membersection{wxZipOutputStream::Close}\label{wxzipoutputstreamclose}
659
660 \func{bool}{Close}{\void}
661
662 Finishes writing the zip, returning true if successful.
663 Called by the destructor if not called explicitly.
664
665
666 \membersection{wxZipOutputStream::CloseEntry}\label{wxzipoutputstreamcloseentry}
667
668 \func{bool}{CloseEntry}{\void}
669
670 Close the current entry. It is called implicitly whenever another new
671 entry is created with \helpref{CopyEntry()}{wxzipoutputstreamcopyentry}
672 or \helpref{PutNextEntry()}{wxzipoutputstreamputnextentry}, or
673 when the zip is closed.

675
676 \membersection{wxZipOutputStream::CopyArchiveMetaData}\label{wxzipoutputstreamcopyarchivemetadata}
677
678 \func{bool}{CopyArchiveMetaData}{\param{wxZipInputStream\& }{inputStream}}
679
680 Transfers the zip comment from the \helpref{wxZipInputStream}{wxzipinputstream}
681 to this output stream.
682
683
684 \membersection{wxZipOutputStream::CopyEntry}\label{wxzipoutputstreamcopyentry}
685
686 \func{bool}{CopyEntry}{\param{wxZipEntry* }{entry}, \param{wxZipInputStream\& }{inputStream}}
687
688 Takes ownership of {\tt entry} and uses it to create a new entry
689 in the zip. {\tt entry} is then opened in {\tt inputStream} and its contents
690 copied to this stream.
691
692 CopyEntry() is much more efficient than transferring the data using
693 Read() and Write() since it will copy them without decompressing and
694 recompressing them.
695
696 For zips on seekable streams, {\tt entry} must be from the same zip file
697 as {\tt stream}. For non-seekable streams, {\tt entry} must also be the
698 last thing read from {\tt inputStream}.

702
703 \constfunc{int}{GetLevel}{\void}
704
705 \func{void}{SetLevel}{\param{int }{level}}
706
707 Set the compression level that will be used the next time an entry is
708 created. It can be a value between 0 and 9 or -1 to use the default value
709 which currently is equivalent to 6.

712 \membersection{wxZipOutputStream::PutNextDirEntry}\label{wxzipoutputstreamputnextdirentry}
713
714 \func{bool}{PutNextDirEntry}{\param{const wxString\& }{name}, \param{const wxDateTime\& }{dt = wxDateTime::Now()}}
715
716 Create a new directory entry
717 (see \helpref{wxArchiveEntry::IsDir()}{wxarchiveentryisdir})
718 with the given name and timestamp.
719
720 \helpref{PutNextEntry()}{wxzipoutputstreamputnextentry} can
721 also be used to create directory entries, by supplying a name with
722 a trailing path separator.
723
724
725 \membersection{wxZipOutputStream::PutNextEntry}\label{wxzipoutputstreamputnextentry}
726
727 \func{bool}{PutNextEntry}{\param{wxZipEntry* }{entry}}
728
729 Takes ownership of {\tt entry} and uses it to create a new entry
730 in the zip.
731
732 \func{bool}{PutNextEntry}{\param{const wxString\& }{name}, \param{const wxDateTime\& }{dt = wxDateTime::Now()}, \param{off\_t }{size = wxInvalidOffset}}
733
734 Create a new entry with the given name, timestamp and size.
735
736
737 \membersection{wxZipOutputStream::SetComment}\label{wxzipoutputstreamsetcomment}
738
739 \func{void}{SetComment}{\param{const wxString\& }{comment}}
740
741 Sets a comment for the zip as a whole. It is written at the end of the
742 zip.
