43 * @class ContentManager
44 * @brief This class provides methods for local content management.
48 * The %ContentManager class manages the information stored locally on the device's content database. @n
49 * It also allows you to create, read, update, and delete specific content information in the database.
51 * For more information on managing content on the device, see <a href="../org.tizen.native.appprogramming/html/guide/content/device_content_mgmt.htm">Device Content Management</a>.
53 * The following example demonstrates how to use the %ContentManager class.
57 * MyClass::TestContentManager(void)
59 * result r = E_SUCCESS;
60 * ContentId contentId;
61 * ContentManager contentManager;
62 * r = contentManager.Construct();
63 * TryReturn(!IsFailed(r), r, "Construct failed.");
66 * ImageContentInfo imageContentInfo;
67 * r = imageContentInfo.Construct(null);
68 * TryReturn(!IsFailed(r), r, "Construct failed.");
70 * r = imageContentInfo.SetKeyword(L"platform, tizen");
76 * r = imageContentInfo.SetLocationTag(L"seoul");
82 * Tizen::Base::String sourcePath = Tizen::App::App::GetInstance()->GetAppRootPath() + L"data/flower.jpg";
83 * Tizen::Base::String destPath = Tizen::System::Environment::GetMediaPath() + L"Images/flower.jpg";
85 * contentId = contentManager.CreateContent(sourcePath, destPath, false, &imageContentInfo);
86 * TryReturn(Tizen::Base::UuId::GetInvalidUuId() != contentId, GetLastResult(), "CreateContent failed.");
89 * ImageContentInfo* pImageContentInfo = null;
90 * pImageContentInfo = dynamic_cast<ImageContentInfo*>(contentManager.GetContentInfoN(contentId));
91 * TryReturn(pImageContentInfo != null, GetLastResult(), "GetContentInfoN failed.");
93 * pImageContentInfo->GetContentPath();
96 * r = pImageContentInfo->SetKeyword(L"apple, fruit");
99 * delete pImageContentInfo;
102 * r = pImageContentInfo->SetProvider(L"kw1128");
105 * delete pImageContentInfo;
108 * r = contentManager.UpdateContent(*pImageContentInfo);
111 * delete pImageContentInfo;
116 * r = contentManager.DeleteContent(contentId);
119 * delete pImageContentInfo;
123 * delete pImageContentInfo;

269 * @section CompContentManagerCreateContentPageIssueSection Issues
270 * The content path argument of this method in OSP compatible applications has the following issues: @n
271 * -# The content path should be a path that begins with an allowed path prefix. @n
272 * For example, L"/Media/Images/flower.jpg", L"/Storagecard/Media/Images/flower.jpg".
274 * @section CompContentManagerCreateContentPageSolutionSection Resolutions
275 * This issue has been resolved in Tizen. @n
276 * -# The content path can be a path without a specific allowed path prefix. @n
277 * Application do not need to know the specific allowed path prefixes. @n
278 * To get the directory path, use the following methods: @n
279 * - For accessing the home directory, use Tizen::App::App::GetInstance()->GetAppRootPath().
280 * - For accessing the media directory, use Tizen::System::Environment::GetMediaPath().
281 * - For accessing the external storage, use Tizen::System::Environment::GetExternalStoragePath().
