151 \wxheading{Field availability}
152
153 When reading a zip from a stream that is seekable,
154 \helpref{GetNextEntry()}{wxzipinputstreamgetnextentry} returns
155 a fully populated wxZipEntry object except for
156 \helpref{wxZipEntry::GetLocalExtra()}{wxzipentrylocalextra}. GetLocalExtra()
157 becomes available when the entry is opened, either by calling
158 \helpref{wxZipInputStream::OpenEntry}{wxzipinputstreamopenentry} or by
159 making an attempt to read the entry's data.
160
161 For zips on \helpref{non-seekable}{wxarcnoseek} streams, the following
162 fields are always available when GetNextEntry() returns:
163
164 \helpref{GetDateTime}{wxarchiveentrydatetime}\\
165 \helpref{GetInternalFormat}{wxarchiveentrygetinternalformat}\\
166 \helpref{GetInternalName}{wxzipentrygetinternalname}\\
167 \helpref{GetFlags}{wxzipentrygetflags}\\
168 \helpref{GetLocalExtra}{wxzipentrylocalextra}\\
169 \helpref{GetMethod}{wxzipentrymethod}\\
170 \helpref{GetName}{wxarchiveentryname}\\
171 \helpref{GetOffset}{wxarchiveentrygetoffset}\\
172 \helpref{IsDir}{wxarchiveentryisdir}
173
174 The following fields are also usually available when GetNextEntry()
175 returns, however, if the zip was also written to a non-seekable stream
176 the zipper is permitted to store them after the entry's data. In that
177 case they become available when the entry's data has been read to Eof(),
178 or \helpref{CloseEntry()}{wxarchiveinputstreamcloseentry} has been called.
179 {\tt (GetFlags() \& wxZIP\_SUMS\_FOLLOW) != 0} indicates that one or
180 more of these come after the data:
181
182 \helpref{GetCompressedSize}{wxzipentrygetcompressedsize}\\
183 \helpref{GetCrc}{wxzipentrygetcrc}\\
184 \helpref{GetSize}{wxarchiveentrysize}
185
186 The following are stored at the end of the zip, and become available
187 when the end of the zip has been reached, i.e. after GetNextEntry()
188 returns NULL and Eof() is true:
189
190 \helpref{GetComment}{wxzipentrycomment}\\

246 \constfunc{wxUint32}{GetExternalAttributes}{\void}
247
248 \func{void}{SetExternalAttributes}{\param{wxUint32 }{attr}}
249
250 The low 8 bits are always the DOS/Windows file attributes for this entry.
251 The values of these attributes are given in the
252 enumeration {\tt wxZipAttributes}.
253
254 The remaining bits can store platform specific permission bits or
255 attributes, and their meaning depends on the value
256 of \helpref{SetSystemMadeBy()}{wxzipentrysystemmadeby}.
257 If \helpref{IsMadeByUnix()}{wxzipentryismadebyunix} is true then the
258 high 16 bits are unix mode bits.
259
260 The following other accessors access these bits:
261
262 \helpref{IsReadOnly/SetIsReadOnly}{wxarchiveentryisreadonly}\\
263 \helpref{IsDir/SetIsDir}{wxarchiveentryisdir}\\
264 \helpref{Get/SetMode}{wxzipentrymode}

270
271 \constfunc{size\_t}{GetExtraLen}{\void}
272
273 \func{void}{SetExtra}{\param{const char* }{extra}, \param{size\_t }{len}}
274
275 The extra field from the entry's central directory record.
276
277 The extra field is used to store platform or application specific
278 data. See Pkware's document 'appnote.txt' for information on its format.
279
280
281 \membersection{wxZipEntry::GetFlags}\label{wxzipentrygetflags}
282
283 \constfunc{int}{GetFlags}{\void}

285 Returns a combination of the bits flags in the enumeration {\tt wxZipFlags}.
286
287
288 \membersection{wxZipEntry::GetInternalName}\label{wxzipentrygetinternalname}
289
290 \constfunc{wxString}{GetInternalName}{\void}
291
292 Returns the entry's filename in the internal format used within the
293 archive. The name can include directory components, i.e. it can be a
294 full path.
295
296 The names of directory entries are returned without any trailing path
297 separator. This gives a canonical name that can be used in comparisons.
298
299 \func{wxString}{GetInternalName}{\param{const wxString\& }{name}, \param{wxPathFormat }{format = wxPATH\_NATIVE}, \param{bool* }{pIsDir = NULL}}
300
301 A static member that translates a filename into the internal format used
302 within the archive. If the third parameter is provided, the bool pointed
303 to is set to indicate whether the name looks like a directory name
304 (i.e. has a trailing path separator).

318
319 The extra field from the entry's local record.
320
321 The extra field is used to store platform or application specific
322 data. See Pkware's document 'appnote.txt' for information on its format.
323

326
327 \constfunc{int}{GetMethod}{\void}
328
329 \func{void}{SetMethod}{\param{int }{method}}
330
331 The compression method. The enumeration {\tt wxZipMethod} lists the
332 possible values.
333
334 The default constructor sets this to wxZIP\_METHOD\_DEFAULT,
335 which allows \helpref{wxZipOutputStream}{wxzipoutputstream} to
336 choose the method when writing the entry.
337
338
339 \membersection{wxZipEntry::Get/SetMode}\label{wxzipentrymode}
340
341 \constfunc{int}{GetMode}{\void}
342
343 If \helpref{IsMadeByUnix()}{wxzipentryismadebyunix} is true then
344 returns the unix permission bits stored in
345 \helpref{GetExternalAttributes()}{wxzipentryexternalattributes}.
346 Otherwise synthesises them from the DOS attributes.
347
348 \func{void}{SetMode}{\param{int }{mode}}
349
350 Sets the DOS attributes
351 in \helpref{GetExternalAttributes()}{wxzipentryexternalattributes}
352 to be consistent with the {\tt mode} given.
353
354 If \helpref{IsMadeByUnix()}{wxzipentryismadebyunix} is true then also
355 stores {\tt mode} in GetExternalAttributes().
356
357 Note that the default constructor
358 sets \helpref{GetSystemMadeBy()}{wxzipentrysystemmadeby} to
359 wxZIP\_SYSTEM\_MSDOS by default. So to be able to store unix
360 permissions when creating zips, call SetSystemMadeBy(wxZIP\_SYSTEM\_UNIX).
361
362
363 \membersection{wxZipEntry::SetNotifier}\label{wxzipentrynotifier}
364
365 \func{void}{SetNotifier}{\param{wxZipNotifier\& }{notifier}}
366
367 \func{void}{UnsetNotifier}{\void}
368
369 Sets the \helpref{notifier}{wxzipnotifier} for this entry.
370 Whenever the \helpref{wxZipInputStream}{wxzipinputstream} updates
371 this entry, it will then invoke the associated
372 notifier's \helpref{OnEntryUpdated}{wxzipnotifieronentryupdated}
373 method.
374
375 Setting a notifier is not usually necessary. It is used to handle
376 certain cases when modifying an zip in a pipeline (i.e. between
377 non-seekable streams).

387 \constfunc{int}{GetSystemMadeBy}{\void}
388
389 \func{void}{SetSystemMadeBy}{\param{int }{system}}
390
391 The originating file-system. The default constructor sets this to
392 wxZIP\_SYSTEM\_MSDOS. Set it to wxZIP\_SYSTEM\_UNIX in order to be
393 able to store unix permissions using \helpref{SetMode()}{wxzipentrymode}.
394

426
427 Input stream for reading zip files.
428
429 \helpref{GetNextEntry()}{wxzipinputstreamgetnextentry} returns an
430 \helpref{wxZipEntry}{wxzipentry} object containing the meta-data
431 for the next entry in the zip (and gives away ownership). Reading from
432 the wxZipInputStream then returns the entry's data. Eof() becomes true
433 after an attempt has been made to read past the end of the entry's data.
434 When there are no more entries, GetNextEntry() returns NULL and sets Eof().
435
436 Note that in general zip entries are not seekable, and
437 wxZipInputStream::SeekI() always returns wxInvalidOffset.

537
538 If you need to know when a \helpref{wxZipInputStream}{wxzipinputstream}
539 updates a \helpref{wxZipEntry}{wxzipentry},
540 you can create a notifier by deriving from this abstract base class,
541 overriding \helpref{OnEntryUpdated()}{wxzipnotifieronentryupdated}.
542 An instance of your notifier class can then be assigned to wxZipEntry
543 objects, using \helpref{wxZipEntry::SetNotifier()}{wxzipentrynotifier}.
544
545 Setting a notifier is not usually necessary. It is used to handle
546 certain cases when modifying an zip in a pipeline (i.e. between
547 non-seekable streams).

585 \helpref{PutNextEntry()}{wxzipoutputstreamputnextentry} is used to create
586 a new entry in the output zip, then the entry's data is written to the
587 wxZipOutputStream. Another call to PutNextEntry() closes the current
588 entry and begins the next.

608
609 \func{}{wxZipOutputStream}{\param{wxOutputStream\& }{stream}, \param{int }{level = -1}, \param{wxMBConv\& }{conv = wxConvLocal}}
610
611 Constructor. {\tt level} is the compression level to use.
612 It can be a value between 0 and 9 or -1 to use the default value
613 which currently is equivalent to 6.
614
615 In a Unicode build the third parameter {\tt conv} is used to translate
616 the filename and comment fields to Unicode. It has no effect on the
617 stream's data.

619
620 \membersection{wxZipOutputStream::\destruct{wxZipOutputStream}}\label{wxzipoutputstreamdtor}
621
622 \func{}{\destruct{wxZipOutputStream}}{\void}
623
624 The destructor calls \helpref{Close()}{wxzipoutputstreamclose} to finish
625 writing the zip if it has not been called already.
626
627
628 \membersection{wxZipOutputStream::Close}\label{wxzipoutputstreamclose}
629
630 \func{bool}{Close}{\void}
631
632 Finishes writing the zip, returning true if successfully.
633 Called by the destructor if not called explicitly.
634
635
636 \membersection{wxZipOutputStream::CloseEntry}\label{wxzipoutputstreamcloseentry}
637
638 \func{bool}{CloseEntry}{\void}
639
640 Close the current entry. It is called implicitly whenever another new
641 entry is created with \helpref{CopyEntry()}{wxzipoutputstreamcopyentry}
642 or \helpref{PutNextEntry()}{wxzipoutputstreamputnextentry}, or
643 when the zip is closed.

645
646 \membersection{wxZipOutputStream::CopyArchiveMetaData}\label{wxzipoutputstreamcopyarchivemetadata}
647
648 \func{bool}{CopyArchiveMetaData}{\param{wxZipInputStream\& }{inputStream}}
649
650 Transfers the zip comment from the \helpref{wxZipInputStream}{wxzipinputstream}
651 to this output stream.
652
653
654 \membersection{wxZipOutputStream::CopyEntry}\label{wxzipoutputstreamcopyentry}
655
656 \func{bool}{CopyEntry}{\param{wxZipEntry* }{entry}, \param{wxZipInputStream\& }{inputStream}}
657
658 Takes ownership of {\tt entry} and uses it to create a new entry
659 in the zip. {\tt entry} is then opened in {\tt inputStream} and its contents
660 copied to this stream.
661
662 CopyEntry() is much more efficient than transferring the data using
663 Read() and Write() since it will copy them without decompressing and
664 recompressing them.
665
666 For zips on seekable streams, {\tt entry} must be from the same zip file
667 as {\tt stream}. For non-seekable streams, {\tt entry} must also be the
668 last thing read from {\tt inputStream}.

672
673 \constfunc{int}{GetLevel}{\void}
674
675 \func{void}{SetLevel}{\param{int }{level}}
676
677 Set the compression level that will be used the next time an entry is
678 created. It can be a value between 0 and 9 or -1 to use the default value
679 which currently is equivalent to 6.

682 \membersection{wxZipOutputStream::PutNextDirEntry}\label{wxzipoutputstreamputnextdirentry}
683
684 \func{bool}{PutNextDirEntry}{\param{const wxString\& }{name}, \param{const wxDateTime\& }{dt = wxDateTime::Now()}}
685
686 Create a new directory entry
687 (see \helpref{wxArchiveEntry::IsDir()}{wxarchiveentryisdir})
688 with the given name and timestamp.
689
690 \helpref{PutNextEntry()}{wxzipoutputstreamputnextentry} can
691 also be used to create directory entries, by supplying a name with
692 a trailing path separator.

694
695 \membersection{wxZipOutputStream::PutNextEntry}\label{wxzipoutputstreamputnextentry}
696
697 \func{bool}{PutNextEntry}{\param{wxZipEntry* }{entry}}
698
699 Takes ownership of {\tt entry} and uses it to create a new entry
700 in the zip.
701
702 \func{bool}{PutNextEntry}{\param{const wxString\& }{name}, \param{const wxDateTime\& }{dt = wxDateTime::Now()}, \param{off\_t }{size = wxInvalidOffset}}
703
704 Create a new entry with the given name, timestamp and size.
705
706
707 \membersection{wxZipOutputStream::SetComment}\label{wxzipoutputstreamsetcomment}
708
709 \func{void}{SetComment}{\param{const wxString\& }{comment}}
710
711 Sets a comment for the zip as a whole. It is written at the end of the
712 zip.
