22 * This header file contains the declarations of the %FileZipper class.

36 * @brief This class provides methods that compress data to a zip-archive using zlib.
40 * The %FileZipper class provides a zip operation for a simple and efficient file-based access to a zip-archive.
41 * It is possible to create a zip file, and add the file to an already existing zip-archive.
43 * For more information on the class features, see <a href="../org.tizen.native.appprogramming/html/guide/base/utility_namespace.htm">Utility</a>.
45 * The following example demonstrates how to use the %FileZipper class.
50 * using namespace Tizen::App;
51 * using namespace Tizen::Base;
52 * using namespace Tizen::Base::Utility;
55 * MyClass::FileZipperSample(void)
58 * String dataPath = App::GetInstance()->GetAppDataPath();
59 * zip.Construct(dataPath + L"sample.zip");
61 * // Adds files to the zip file-archive
62 * zip.AddToZip(dataPath + L"data1.txt");
63 * zip.AddToZip(dataPath + L"dataDir/data2.txt");
67 class _OSP_EXPORT_ FileZipper
68 : public Tizen::Base::Object
72 * The object is not fully constructed after this constructor is called. @n
73 * For full construction, the Construct() method must be called right after calling this constructor.
80 * This destructor overrides Tizen::Base::Object::~Object().
84 virtual ~FileZipper(void);
87 * Initializes this instance of %FileZipper with the specified filepath. @n
88 * This method opens an existing zip file in append mode. If the file does not exist, it creates and opens the file in
92 * @brief <i> [Compatibility] </i>
96 * @compatibility This method has compatibility issues with OSP compatible applications. @n
97 * For more information, see @ref CompIoPathPage "here".
100 * @return An error code
101 * @param [in] filePath The path of the zip file to open or create
102 * @exception E_SUCCESS The method is successful.
103 * @exception E_INVALID_ARG Either of the following conditions has occurred: @n
104 * - The length of the specified path is @c 0 or exceeds system limitations. @n
105 * - The specified path contains prohibited character(s). @n
106 * - The specified path is invalid.
107 * @exception E_ILLEGAL_ACCESS The specified path is not permitted, or
108 * access is denied due to insufficient permission.
109 * @exception E_IO An unexpected device failure has occurred.
110 * @remarks The paths for @b Tizen::App::AppManager::GetAppSharedPath(appId) + L"data" and @b Tizen::App::AppManager::GetAppSharedPath(appId) + L"trusted" are not supported.
111 * @see Tizen::Io::File
113 result Construct(const String& filePath);
116 * Adds a new file to an already opened zip file.
119 * @brief <i> [Compatibility] </i>
123 * @compatibility This method has compatibility issues with OSP compatible applications. @n
124 * For more information, see @ref CompIoPathPage "here".
127 * @return An error code
128 * @param [in] filePath The path of the file to add to the zip file
129 * @param [in] excludePath Set to @c true to exclude the path and to store only the file name, @n
130 * else @c false to insert the entire path name in the zip-archive
131 * @param [in] level Set to @c BEST_SPEED or @c BEST_COMPRESSION @n
132 * By default, it is set to @c DEFAULT_COMPRESSION.
133 * @exception E_SUCCESS The method is successful.
134 * @exception E_INVALID_ARG Either of the following conditions has occurred: @n
135 * - The length of the specified path is @c 0 or exceeds system limitations. @n
136 * - The specified path contains prohibited character(s). @n
137 * - The specified path is invalid.
138 * @exception E_ILLEGAL_ACCESS The specified path is not permitted, or
139 * access is denied due to insufficient permission.
140 * @exception E_FILE_NOT_FOUND The specified file cannot be found.
141 * @exception E_FILE_ALREADY_EXIST The specified file already exists in the zip-archive, but the
142 * flag for overwriting the file is not set.
143 * @exception E_IO An unexpected device failure has occurred.
144 * @remarks The paths for @b Tizen::App::AppManager::GetAppSharedPath(appId) + L"data" and @b Tizen::App::AppManager::GetAppSharedPath(appId) + L"trusted" are not supported.
145 * @remarks If the value of @c excludePath is set to @c false, full path name is inserted to the zip-
146 * archive. Therefore, developers should handle the path name carefully. @n
147 * For example, if you add @b '/Test/data.txt' file to the zip-archive, and if the
148 * @c excludePath parameter is set to @c false, while unzipping the file in @b '/Test'
149 * directory, then the file is extracted in @b '/Test/Test/data.txt'.
150 * @see Tizen::Io::File
152 result AddToZip(const String& filePath, bool excludePath = true, CompressionLevel level = DEFAULT_COMPRESSION);
155 * Gets the value of the overwritten flag. @n
156 * If @c true, it overwrites the existing file.
160 * @return The value of the overwrite flag for the zip file
162 bool GetOverwriteFlag(void) const;
165 * Sets the value of the overwritten flag. @n
166 * If @c true, the existing file gets overwritten during file addition.
167 * The default value of this flag is @c false.
171 * @param [in] flag The flag value to set
173 void SetOverwriteFlag(bool flag);
