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}\\

236
237 \membersection{wxZipEntry::GetCrc}\label{wxzipentrygetcrc}
238
239 \constfunc{wxUint32}{GetCrc}{\void}

245
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}
284
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.

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.

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).

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

427 Input stream for reading zip files.

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().

530
531 If you need to know when a \helpref{wxZipInputStream}{wxzipinputstream}
532 updates a \helpref{wxZipEntry}{wxzipentry},
533 you can create a notifier by deriving from this abstract base class,
534 overriding \helpref{OnEntryUpdated()}{wxzipnotifieronentryupdated}.
535 An instance of your notifier class can then be assigned to wxZipEntry
536 objects, using \helpref{wxZipEntry::SetNotifier()}{wxzipentrynotifier}.
537
538 Setting a notifier is not usually necessary. It is used to handle
539 certain cases when modifying an zip in a pipeline (i.e. between
540 non-seekable streams).

576 Output stream for writing zip files.
577
578 \helpref{PutNextEntry()}{wxzipoutputstreamputnextentry} is used to create
579 a new entry in the output zip, then the entry's data is written to the

601
602 \func{}{wxZipOutputStream}{\param{wxOutputStream\& }{stream}, \param{int }{level = -1}, \param{wxMBConv\& }{conv = wxConvLocal}}
603
604 Constructor. {\tt level} is the compression level to use.
605 It can be a value between 0 and 9 or -1 to use the default value
606 which currently is equivalent to 6.
607
608 In a Unicode build the third parameter {\tt conv} is used to translate
609 the filename and comment fields to Unicode. It has no effect on the
610 stream's data.

612
613 \membersection{wxZipOutputStream::\destruct{wxZipOutputStream}}\label{wxzipoutputstreamdtor}
614
615 \func{}{\destruct{wxZipOutputStream}}{\void}
616
617 The destructor calls \helpref{Close()}{wxzipoutputstreamclose} to finish
618 writing the zip if it has not been called already.
619
620
621 \membersection{wxZipOutputStream::Close}\label{wxzipoutputstreamclose}
622
623 \func{bool}{Close}{\void}
624
625 Finishes writing the zip, returning true if successfully.
626 Called by the destructor if not called explicitly.
627
628
629 \membersection{wxZipOutputStream::CloseEntry}\label{wxzipoutputstreamcloseentry}
630
631 \func{bool}{CloseEntry}{\void}
632
633 Close the current entry. It is called implicitly whenever another new
634 entry is created with \helpref{CopyEntry()}{wxzipoutputstreamcopyentry}
635 or \helpref{PutNextEntry()}{wxzipoutputstreamputnextentry}, or
636 when the zip is closed.

638
639 \membersection{wxZipOutputStream::CopyArchiveMetaData}\label{wxzipoutputstreamcopyarchivemetadata}
640
641 \func{bool}{CopyArchiveMetaData}{\param{wxZipInputStream\& }{inputStream}}
642
643 Transfers the zip comment from the \helpref{wxZipInputStream}{wxzipinputstream}
644 to this output stream.
645
646
647 \membersection{wxZipOutputStream::CopyEntry}\label{wxzipoutputstreamcopyentry}
648
649 \func{bool}{CopyEntry}{\param{wxZipEntry* }{entry}, \param{wxZipInputStream\& }{inputStream}}
650
651 Takes ownership of {\tt entry} and uses it to create a new entry
652 in the zip. {\tt entry} is then opened in {\tt inputStream} and its contents
653 copied to this stream.
654
655 CopyEntry() is much more efficient than transferring the data using
656 Read() and Write() since it will copy them without decompressing and
657 recompressing them.
658
659 For zips on seekable streams, {\tt entry} must be from the same zip file
660 as {\tt stream}. For non-seekable streams, {\tt entry} must also be the
661 last thing read from {\tt inputStream}.

665
666 \constfunc{int}{GetLevel}{\void}
667
668 \func{void}{SetLevel}{\param{int }{level}}
669
670 Set the compression level that will be used the next time an entry is
671 created. It can be a value between 0 and 9 or -1 to use the default value
672 which currently is equivalent to 6.
673
674
675 \membersection{wxZipOutputStream::PutNextDirEntry}\label{wxzipoutputstreamputnextdirentry}
676
677 \func{bool}{PutNextDirEntry}{\param{const wxString\& }{name}, \param{const wxDateTime\& }{dt = wxDateTime::Now()}}
678
679 Create a new directory entry
680 (see \helpref{wxArchiveEntry::IsDir()}{wxarchiveentryisdir})
681 with the given name and timestamp.
682
683 \helpref{PutNextEntry()}{wxzipoutputstreamputnextentry} can
684 also be used to create directory entries, by supplying a name with
685 a trailing path separator.
686
687
688 \membersection{wxZipOutputStream::PutNextEntry}\label{wxzipoutputstreamputnextentry}
689
690 \func{bool}{PutNextEntry}{\param{wxZipEntry* }{entry}}
691
692 Takes ownership of {\tt entry} and uses it to create a new entry
693 in the zip.
694
695 \func{bool}{PutNextEntry}{\param{const wxString\& }{name}, \param{const wxDateTime\& }{dt = wxDateTime::Now()}, \param{off\_t }{size = wxInvalidOffset}}
696
697 Create a new entry with the given name, timestamp and size.
698
699
700 \membersection{wxZipOutputStream::SetComment}\label{wxzipoutputstreamsetcomment}
701
702 \func{void}{SetComment}{\param{const wxString\& }{comment}}
703
704 Sets a comment for the zip as a whole. It is written at the end of the
705 zip.
