ZFCompressOpen()

zfautoT< ZFCompressToken > ZFCompressOpen ( const ZFPathInfo & pathInfo, ZFIOOpenOptionFlags flags, ZFCompressLevel compressLevel = (v_ZFCompressLevel::EnumDefault()) )

extern

open compress file for read or write

typical usage:

zfautoT<ZFCompressToken> compress = ZFCompressOpen(pathInfo, v_ZFIOOpenOption::e_Modify);
 
// read and write file in the compress file
compress->read(ZFOutputForXxx(), "item/path/in/compress_file");
compress->write("item/path/in/compress_file", ZFInputForXxx());
 
// find files in compress file
ZFIOFindData fd;
if(compress->itemFindFirst(fd, "item/path/in/compress_file")) {
    do {
        ...
    } while(compress->itemFindNext(fd));
    compress->itemFindClose(fd);
}
 
// iterate items (files or dirs)
for(zfindex i = 0; i < compress->itemCount(); ++i) {
    zfstring itemPath = compress->itemPath(i);
}
 
// explicitly close
// would be closed automatically when compress object deallocated
compress->close();

ZFCompressDir()

zfbool ZFCompressDir ( const ZFPathInfo & outputCompress, const ZFPathInfo & inputPathInfo, const zfstring & itemPath = (zft_zfnull), ZFIOOpenOptionFlags flags = (v_ZFIOOpenOption::e_Modify), ZFCompressLevel compressLevel = (v_ZFCompressLevel::EnumDefault()) )

example of different conditions:

• itemPath is empty : inputPathInfo's file name would be used as itemPath in compress file

  some_path/dir_name/    <= inputPathInfo
      some_file
   
  compress_name.zip      <= outputCompress
      dir_name/          <= file name specified by inputPathInfo
          some_file      <= children of inputPathInfo

• itemPath is "." : all children would be added to root of the compress file

  some_path/dir_name/    <= inputPathInfo
      some_file
   
  compress_name.zip      <= outputCompress
      some_file          <= children of inputPathInfo would be added to root

• itemPath is valid path : all children would be added to specified itemPath

  some_path/dir_name/    <= inputPathInfo
      some_file
   
  compress_name.zip      <= outputCompress
      some/item/path/
          some_file      <= children of inputPathInfo would be added to specified itemPath
