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

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

272
273\func{void}{SetExtra}{\param{const char* }{extra}, \param{size\_t }{len}}
274
275The extra field from the entry's central directory record.
276
277The extra field is used to store platform or application specific
278data. See Pkware's document 'appnote.txt' for information on its format.

288\membersection{wxZipEntry::GetInternalName}\label{wxzipentrygetinternalname}
289
290\constfunc{wxString}{GetInternalName}{\void}
291
292Returns the entry's filename in the internal format used within the
293archive. The name can include directory components, i.e. it can be a
294full path.
295
296The names of directory entries are returned without any trailing path
297separator. 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
301A static member that translates a filename into the internal format used
302within the archive. If the third parameter is provided, the bool pointed
303to is set to indicate whether the name looks like a directory name
304(i.e. has a trailing path separator).

318
319The extra field from the entry's local record.

321The extra field is used to store platform or application specific
322data. 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
331The compression method. The enumeration {\tt wxZipMethod} lists the
332possible values.
333
334The default constructor sets this to wxZIP\_METHOD\_DEFAULT,
335which allows \helpref{wxZipOutputStream}{wxzipoutputstream} to
336choose the method when writing the entry.
337
338
339\membersection{wxZipEntry::Get/SetMode}\label{wxzipentrymode}
340
341\constfunc{int}{GetMode}{\void}
342
343If \helpref{IsMadeByUnix()}{wxzipentryismadebyunix} is true then
344returns the unix permission bits stored in
345 \helpref{GetExternalAttributes()}{wxzipentryexternalattributes}.
346Otherwise synthesises them from the DOS attributes.
347
348\func{void}{SetMode}{\param{int }{mode}}
349
350Sets the DOS attributes
351in \helpref{GetExternalAttributes()}{wxzipentryexternalattributes}
352to be consistent with the {\tt mode} given.
353
354If \helpref{IsMadeByUnix()}{wxzipentryismadebyunix} is true then also
355stores {\tt mode} in GetExternalAttributes().
356
357Note that the default constructor
358sets \helpref{GetSystemMadeBy()}{wxzipentrysystemmadeby} to
359wxZIP\_SYSTEM\_MSDOS by default. So to be able to store unix
360permissions when creating zips, call SetSystemMadeBy(wxZIP\_SYSTEM\_UNIX).

363\membersection{wxZipEntry::SetNotifier}\label{wxzipentrynotifier}
364
365\func{void}{SetNotifier}{\param{wxZipNotifier\& }{notifier}}
366
367\func{void}{UnsetNotifier}{\void}
368
369Sets the \helpref{notifier}{wxzipnotifier} for this entry.
370Whenever the \helpref{wxZipInputStream}{wxzipinputstream} updates
371this entry, it will then invoke the associated
372notifier's \helpref{OnEntryUpdated}{wxzipnotifieronentryupdated}
373method.
374
375Setting a notifier is not usually necessary. It is used to handle
376certain cases when modifying an zip in a pipeline (i.e. between
377non-seekable streams).

432the wxZipInputStream then returns the entry's data. Eof() becomes true
433after an attempt has been made to read past the end of the entry's data.
434When there are no more entries, GetNextEntry() returns NULL and sets Eof().

545you can create a notifier by deriving from this abstract base class,
546overriding \helpref{OnEntryUpdated()}{wxzipnotifieronentryupdated}.
547An instance of your notifier class can then be assigned to wxZipEntry
548objects, using \helpref{wxZipEntry::SetNotifier()}{wxzipentrynotifier}.
549
550Setting a notifier is not usually necessary. It is used to handle
551certain cases when modifying an zip in a pipeline (i.e. between
552non-seekable streams).
553See '\helpref{Archives on non-seekable streams}{wxarcnoseek}'.

587
588Output stream for writing zip files.
589
590\helpref{PutNextEntry()}{wxzipoutputstreamputnextentry} is used to create
591a new entry in the output zip, then the entry's data is written to the
592wxZipOutputStream. Another call to PutNextEntry() closes the current
593entry and begins the next.

VZ
618Constructor. {\tt level} is the compression level to use.
619It can be a value between 0 and 9 or -1 to use the default value
620which currently is equivalent to 6.

622If the parent stream is passed as a pointer then the new filter stream
623takes ownership of it. If it is passed by reference then it does not.
624
00375592 625In a Unicode build the third parameter {\tt conv} is used to translate
08202189 626the filename and comment fields to an 8-bit encoding. It has no effect on the
00375592

627stream's data.

632\func{}{\destruct{wxZipOutputStream}}{\void}

634The destructor calls \helpref{Close()}{wxzipoutputstreamclose} to finish
635writing the zip if it has not been called already.

646\membersection{wxZipOutputStream::CloseEntry}\label{wxzipoutputstreamcloseentry}
647
648\func{bool}{CloseEntry}{\void}
649
650Close the current entry. It is called implicitly whenever another new
651entry is created with \helpref{CopyEntry()}{wxzipoutputstreamcopyentry}
652or \helpref{PutNextEntry()}{wxzipoutputstreamputnextentry}, or
653when the zip is closed.

656\membersection{wxZipOutputStream::CopyArchiveMetaData}\label{wxzipoutputstreamcopyarchivemetadata}
657
658\func{bool}{CopyArchiveMetaData}{\param{wxZipInputStream\& }{inputStream}}
659
660Transfers the zip comment from the \helpref{wxZipInputStream}{wxzipinputstream}
661to this output stream.
662
663
664\membersection{wxZipOutputStream::CopyEntry}\label{wxzipoutputstreamcopyentry}
665
666\func{bool}{CopyEntry}{\param{wxZipEntry* }{entry}, \param{wxZipInputStream\& }{inputStream}}
667
668Takes ownership of {\tt entry} and uses it to create a new entry
669in the zip. {\tt entry} is then opened in {\tt inputStream} and its contents
670copied to this stream.
671
672CopyEntry() is much more efficient than transferring the data using
673Read() and Write() since it will copy them without decompressing and
674recompressing them.
675
676For zips on seekable streams, {\tt entry} must be from the same zip file
677as {\tt stream}. For non-seekable streams, {\tt entry} must also be the
678last thing read from {\tt inputStream}.

687Set the compression level that will be used the next time an entry is
688created. It can be a value between 0 and 9 or -1 to use the default value
689which currently is equivalent to 6.

698with the given name and timestamp.
699
700\helpref{PutNextEntry()}{wxzipoutputstreamputnextentry} can
701also be used to create directory entries, by supplying a name with
702a trailing path separator.
