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

| 180 | \helpref{GetName}{wxarchiveentryname}\\ |
| 181 | \helpref{GetOffset}{wxarchiveentrygetoffset}\\ |
| 182 | \helpref{IsDir}{wxarchiveentryisdir} |
| 183 | |
| 184 | The following fields are also usually available when GetNextEntry() |
| 185 | returns, however, if the zip was also written to a non-seekable stream |
| 186 | the zipper is permitted to store them after the entry's data. In that |
| 187 | case they become available when the entry's data has been read to Eof(), |
| 188 | or \helpref{CloseEntry()}{wxarchiveinputstreamcloseentry} has been called. |
| 189 | {\tt (GetFlags() \& wxZIP\_SUMS\_FOLLOW) != 0} indicates that one or |
| 190 | more of these come after the data: |
| 191 | |
| 192 | \helpref{GetCompressedSize}{wxzipentrygetcompressedsize}\\ |
| 193 | \helpref{GetCrc}{wxzipentrygetcrc}\\ |
| 194 | \helpref{GetSize}{wxarchiveentrysize} |
| 195 | |
| 196 | The following are stored at the end of the zip, and become available |
| 197 | when the end of the zip has been reached, i.e. after GetNextEntry() |
| 198 | returns NULL and Eof() is true: |
| 199 | |
| 200 | \helpref{GetComment}{wxzipentrycomment}\\ |

| 257 | |
| 258 | \func{void}{SetExternalAttributes}{\param{wxUint32 }{attr}} |
| 259 | |
| 260 | The low 8 bits are always the DOS/Windows file attributes for this entry. |
| 261 | The values of these attributes are given in the |
| 262 | enumeration {\tt wxZipAttributes}. |
| 263 | |
| 264 | The remaining bits can store platform specific permission bits or |
| 265 | attributes, and their meaning depends on the value |
| 266 | of \helpref{SetSystemMadeBy()}{wxzipentrysystemmadeby}. |
| 267 | If \helpref{IsMadeByUnix()}{wxzipentryismadebyunix} is true then the |
| 268 | high 16 bits are unix mode bits. |
| 269 | |
| 270 | The following other accessors access these bits: |
| 271 | |
| 272 | \helpref{IsReadOnly/SetIsReadOnly}{wxarchiveentryisreadonly}\\ |
| 273 | \helpref{IsDir/SetIsDir}{wxarchiveentryisdir}\\ |

| 284 | |
| 285 | The extra field from the entry's central directory record. |
| 286 | |
| 287 | The extra field is used to store platform or application specific |
| 288 | data. See Pkware's document 'appnote.txt' for information on its format. |

| 298 | \membersection{wxZipEntry::GetInternalName}\label{wxzipentrygetinternalname} |
| 299 | |
| 300 | \constfunc{wxString}{GetInternalName}{\void} |
| 301 | |
| 302 | Returns the entry's filename in the internal format used within the |
| 303 | archive. The name can include directory components, i.e. it can be a |
| 304 | full path. |
| 305 | |
| 306 | The names of directory entries are returned without any trailing path |
| 307 | separator. This gives a canonical name that can be used in comparisons. |
| 308 | |
| 309 | \func{wxString}{GetInternalName}{\param{const wxString\& }{name}, \param{wxPathFormat }{format = wxPATH\_NATIVE}, \param{bool* }{pIsDir = NULL}} |
| 310 | |
| 311 | A static member that translates a filename into the internal format used |
| 312 | within the archive. If the third parameter is provided, the bool pointed |
| 313 | to is set to indicate whether the name looks like a directory name |
| 314 | (i.e. has a trailing path separator). |

| 328 | |
| 329 | The extra field from the entry's local record. |
| 330 | |
| 331 | The extra field is used to store platform or application specific |
| 332 | data. See Pkware's document 'appnote.txt' for information on its format. |

| 337 | \constfunc{int}{GetMethod}{\void} |
| 338 | |
| 339 | \func{void}{SetMethod}{\param{int }{method}} |
| 340 | |
| 341 | The compression method. The enumeration {\tt wxZipMethod} lists the |
| 342 | possible values. |
| 343 | |
| 344 | The default constructor sets this to wxZIP\_METHOD\_DEFAULT, |
| 345 | which allows \helpref{wxZipOutputStream}{wxzipoutputstream} to |
| 346 | choose the method when writing the entry. |
| 347 | |
| 348 | |
| 349 | \membersection{wxZipEntry::Get/SetMode}\label{wxzipentrymode} |
| 350 | |
| 351 | \constfunc{int}{GetMode}{\void} |
| 352 | |
| 353 | If \helpref{IsMadeByUnix()}{wxzipentryismadebyunix} is true then |
| 354 | returns the unix permission bits stored in |
| 355 | \helpref{GetExternalAttributes()}{wxzipentryexternalattributes}. |
| 356 | Otherwise synthesises them from the DOS attributes. |
| 357 | |
| 358 | \func{void}{SetMode}{\param{int }{mode}} |
| 359 | |
| 360 | Sets the DOS attributes |
| 361 | in \helpref{GetExternalAttributes()}{wxzipentryexternalattributes} |
| 362 | to be consistent with the {\tt mode} given. |
| 363 | |
| 364 | If \helpref{IsMadeByUnix()}{wxzipentryismadebyunix} is true then also |
| 365 | stores {\tt mode} in GetExternalAttributes(). |
| 366 | |
| 367 | Note that the default constructor |
| 368 | sets \helpref{GetSystemMadeBy()}{wxzipentrysystemmadeby} to |
| 369 | wxZIP\_SYSTEM\_MSDOS by default. So to be able to store unix |
| 370 | permissions when creating zips, call SetSystemMadeBy(wxZIP\_SYSTEM\_UNIX). |
| 371 | |
| 372 | |
| 373 | \membersection{wxZipEntry::SetNotifier}\label{wxzipentrynotifier} |
| 374 | |
| 375 | \func{void}{SetNotifier}{\param{wxZipNotifier\& }{notifier}} |
| 376 | |
| 377 | \func{void}{UnsetNotifier}{\void} |
| 378 | |
| 379 | Sets the \helpref{notifier}{wxzipnotifier} for this entry. |
| 380 | Whenever the \helpref{wxZipInputStream}{wxzipinputstream} updates |
| 381 | this entry, it will then invoke the associated |
| 382 | notifier's \helpref{OnEntryUpdated}{wxzipnotifieronentryupdated} |
| 383 | method. |
| 384 | |
| 385 | Setting a notifier is not usually necessary. It is used to handle |
| 386 | certain cases when modifying an zip in a pipeline (i.e. between |
| 387 | non-seekable streams). |

| 398 | |
| 399 | \func{void}{SetSystemMadeBy}{\param{int }{system}} |
| 400 | |
| 401 | The originating file-system. The default constructor sets this to |
| 402 | wxZIP\_SYSTEM\_MSDOS. Set it to wxZIP\_SYSTEM\_UNIX in order to be |
| 403 | able to store unix permissions using \helpref{SetMode()}{wxzipentrymode}. |

| 437 | Input stream for reading zip files. |
| 438 | |
| 439 | \helpref{GetNextEntry()}{wxzipinputstreamgetnextentry} returns an |
| 440 | \helpref{wxZipEntry}{wxzipentry} object containing the meta-data |
| 441 | for the next entry in the zip (and gives away ownership). Reading from |
| 442 | the wxZipInputStream then returns the entry's data. Eof() becomes true |
| 443 | after an attempt has been made to read past the end of the entry's data. |
| 444 | When there are no more entries, GetNextEntry() returns NULL and sets Eof(). |
| 445 | |
| 446 | Note that in general zip entries are not seekable, and |
| 447 | wxZipInputStream::SeekI() always returns wxInvalidOffset. |

| 484 | Constructor. In a Unicode build the second parameter {\tt conv} is |
| 485 | used to translate the filename and comment fields into Unicode. It has |
| 486 | no effect on the stream's data. |
| 487 | |
| 488 | If the parent stream is passed as a pointer then the new filter stream |
| 489 | takes ownership of it. If it is passed by reference then it does not. |

| 501 | |
| 502 | \func{bool}{CloseEntry}{\void} |
| 503 | |
| 504 | Closes the current entry. On a non-seekable stream reads to the end of |

| 510 | \func{wxString}{GetComment}{\void} |
| 511 | |
| 512 | Returns the zip comment. |
| 513 | |
| 514 | This is stored at the end of the zip, therefore when reading a zip |
| 515 | from a non-seekable stream, it returns the empty string until the |
| 516 | end of the zip has been reached, i.e. when GetNextEntry() returns |
| 517 | NULL. |

| 521 | |
| 522 | \func{wxZipEntry*}{GetNextEntry}{\void} |
| 523 | |
| 524 | Closes the current entry if one is open, then reads the meta-data for |
| 525 | the next entry and returns it in a \helpref{wxZipEntry}{wxzipentry} |
| 526 | object, giving away ownership. The stream is then open and can be read. |
| 527 | |

| 529 | \membersection{wxZipInputStream::GetTotalEntries}\label{wxzipinputstreamgettotalentries} |
| 530 | |

| 532 | |
| 533 | For a zip on a seekable stream returns the total number of entries in |
| 534 | the zip. For zips on non-seekable streams returns the number of entries |
| 535 | returned so far by \helpref{GetNextEntry()}{wxzipinputstreamgetnextentry}. |

| 542 | Closes the current entry if one is open, then opens the entry specified |
| 543 | by the {\it entry} object. |
| 544 | |
| 545 | {\it entry} should be from the same zip file, and the zip should |
| 546 | be on a seekable stream. |

| 559 | |
| 560 | If you need to know when a \helpref{wxZipInputStream}{wxzipinputstream} |
| 561 | updates a \helpref{wxZipEntry}{wxzipentry}, |
| 562 | you can create a notifier by deriving from this abstract base class, |
| 563 | overriding \helpref{OnEntryUpdated()}{wxzipnotifieronentryupdated}. |
| 564 | An instance of your notifier class can then be assigned to wxZipEntry |
| 565 | objects, using \helpref{wxZipEntry::SetNotifier()}{wxzipentrynotifier}. |
| 566 | |
| 567 | Setting a notifier is not usually necessary. It is used to handle |
| 568 | certain cases when modifying an zip in a pipeline (i.e. between |
| 569 | non-seekable streams). |

| 608 | |
| 609 | Output stream for writing zip files. |
| 610 | |
| 611 | \helpref{PutNextEntry()}{wxzipoutputstreamputnextentry} is used to create |
| 612 | a new entry in the output zip, then the entry's data is written to the |
| 613 | wxZipOutputStream. Another call to PutNextEntry() closes the current |
| 614 | entry and begins the next. |

| 643 | |
| 644 | \func{}{wxZipOutputStream}{\param{wxOutputStream*}{stream}, \param{int }{level = -1}, \param{wxMBConv\& }{conv = wxConvLocal}} |
| 645 | |
| 646 | Constructor. {\tt level} is the compression level to use. |
| 647 | It can be a value between 0 and 9 or -1 to use the default value |
| 648 | which currently is equivalent to 6. |
| 649 | |
| 650 | If the parent stream is passed as a pointer then the new filter stream |
| 651 | takes ownership of it. If it is passed by reference then it does not. |
| 652 | |
| 653 | In a Unicode build the third parameter {\tt conv} is used to translate |
| 654 | the filename and comment fields to an 8-bit encoding. It has no effect on the |
| 655 | stream's data. |
| 656 | |
| 657 | |
| 658 | \membersection{wxZipOutputStream::\destruct{wxZipOutputStream}}\label{wxzipoutputstreamdtor} |
| 659 | |
| 660 | \func{}{\destruct{wxZipOutputStream}}{\void} |
| 661 | |
| 662 | The destructor calls \helpref{Close()}{wxzipoutputstreamclose} to finish |
| 663 | writing the zip if it has not been called already. |
| 664 | |
| 665 | |
| 666 | \membersection{wxZipOutputStream::Close}\label{wxzipoutputstreamclose} |
| 667 | |
| 668 | \func{bool}{Close}{\void} |
| 669 | |
| 670 | Finishes writing the zip, returning true if successful. |
| 671 | Called by the destructor if not called explicitly. |
| 672 | |
| 673 | |
| 674 | \membersection{wxZipOutputStream::CloseEntry}\label{wxzipoutputstreamcloseentry} |
| 675 | |
| 676 | \func{bool}{CloseEntry}{\void} |
| 677 | |
| 678 | Close the current entry. It is called implicitly whenever another new |
| 679 | entry is created with \helpref{CopyEntry()}{wxzipoutputstreamcopyentry} |
| 680 | or \helpref{PutNextEntry()}{wxzipoutputstreamputnextentry}, or |
| 681 | when the zip is closed. |
| 682 | |
| 683 | |
| 684 | \membersection{wxZipOutputStream::CopyArchiveMetaData}\label{wxzipoutputstreamcopyarchivemetadata} |
| 685 | |
| 686 | \func{bool}{CopyArchiveMetaData}{\param{wxZipInputStream\& }{inputStream}} |
| 687 | |
| 688 | Transfers the zip comment from the \helpref{wxZipInputStream}{wxzipinputstream} |
| 689 | to this output stream. |
| 690 | |
| 691 | |
| 692 | \membersection{wxZipOutputStream::CopyEntry}\label{wxzipoutputstreamcopyentry} |
| 693 | |
| 694 | \func{bool}{CopyEntry}{\param{wxZipEntry* }{entry}, \param{wxZipInputStream\& }{inputStream}} |
| 695 | |
| 696 | Takes ownership of {\tt entry} and uses it to create a new entry |
| 697 | in the zip. {\tt entry} is then opened in {\tt inputStream} and its contents |
| 698 | copied to this stream. |
| 699 | |
| 700 | CopyEntry() is much more efficient than transferring the data using |
| 701 | Read() and Write() since it will copy them without decompressing and |
| 702 | recompressing them. |
| 703 | |
| 704 | For zips on seekable streams, {\tt entry} must be from the same zip file |
| 705 | as {\tt stream}. For non-seekable streams, {\tt entry} must also be the |
| 706 | last thing read from {\tt inputStream}. |
| 707 | |
| 708 | |
| 709 | \membersection{wxZipOutputStream::Get/SetLevel}\label{wxzipoutputstreamlevel} |
| 710 | |
| 711 | \constfunc{int}{GetLevel}{\void} |
| 712 | |
| 713 | \func{void}{SetLevel}{\param{int }{level}} |
| 714 | |
| 715 | Set the compression level that will be used the next time an entry is |
| 716 | created. It can be a value between 0 and 9 or -1 to use the default value |
| 717 | which currently is equivalent to 6. |
| 718 | |
| 719 | |
| 720 | \membersection{wxZipOutputStream::PutNextDirEntry}\label{wxzipoutputstreamputnextdirentry} |
| 721 | |
| 722 | \func{bool}{PutNextDirEntry}{\param{const wxString\& }{name}, \param{const wxDateTime\& }{dt = wxDateTime::Now()}} |
| 723 | |
| 724 | Create a new directory entry |
| 725 | (see \helpref{wxArchiveEntry::IsDir()}{wxarchiveentryisdir}) |
| 726 | with the given name and timestamp. |
| 727 | |
| 728 | \helpref{PutNextEntry()}{wxzipoutputstreamputnextentry} can |
| 729 | also be used to create directory entries, by supplying a name with |
| 730 | a trailing path separator. |
| 731 | |
| 732 | |
| 733 | \membersection{wxZipOutputStream::PutNextEntry}\label{wxzipoutputstreamputnextentry} |
| 734 | |
| 735 | \func{bool}{PutNextEntry}{\param{wxZipEntry* }{entry}} |
| 736 | |
| 737 | Takes ownership of {\tt entry} and uses it to create a new entry |
| 738 | in the zip. |
| 739 | |
| 740 | \func{bool}{PutNextEntry}{\param{const wxString\& }{name}, \param{const wxDateTime\& }{dt = wxDateTime::Now()}, \param{off\_t }{size = wxInvalidOffset}} |
| 741 | |
| 742 | Create a new entry with the given name, timestamp and size. |
| 743 | |
| 744 | |
| 745 | \membersection{wxZipOutputStream::SetComment}\label{wxzipoutputstreamsetcomment} |
| 746 | |
| 747 | \func{void}{SetComment}{\param{const wxString\& }{comment}} |
| 748 | |
| 749 | Sets a comment for the zip as a whole. It is written at the end of the |
| 750 | zip. |
