35 * @class AudioContentInfo
36 * @brief This class provides methods to access the audio content information.
40 * @final This class is not intended for extension.
42 * The %AudioContentInfo class provides methods to access the audio content information that is extracted from a physical file. @n
43 * Before getting the audio content information, ContentManager must be used to create the content.
45 * For more information on the class features, see <a href="../org.tizen.native.appprogramming/html/guide/content/device_content_attributes.htm#media">Device Content Attributes</a>.
47 * The following example demonstrates how to use the %AudioContentInfo class.
51 * MyClass::TestAudioContentInfo(void)
53 * result r = E_SUCCESS;
55 * ContentId contentId;
56 * ContentManager contentManager;
57 * r = contentManager.Construct();
58 * TryReturn(!IsFailed(r), r, "Construct failed.");
60 * AudioContentInfo audioContentInfo;
61 * r = audioContentInfo.Construct(null);
62 * TryReturn(!IsFailed(r), r, "Construct failed.");
64 * Tizen::Base::String sourcePath = Tizen::App::App::GetInstance()->GetAppRootPath() + L"data/flower.wma";
65 * Tizen::Base::String destPath = Tizen::System::Environment::GetMediaPath() + L"Sounds/flower.wma";
67 * contentId = contentManager.CreateContent(sourcePath, destPath, false, &audioContentInfo);
68 * TryReturn(Tizen::Base::UuId::GetInvalidUuId() != contentId, GetLastResult(), "CreateContent failed.");
74 class _OSP_EXPORT_ AudioContentInfo
75 : public Tizen::Content::ContentInfo
79 * The object is not fully constructed after this constructor is called. @n
80 * For full construction, the Construct() method must be called right after calling this constructor.
84 AudioContentInfo(void);
87 * This destructor overrides Tizen::Base::Object::~Object().
91 virtual ~AudioContentInfo(void);
94 * Initializes this instance of %AudioContentInfo with the specified parameter.
97 * @brief <i> [Compatibility] </i>
101 * @compatibility This method has compatibility issues with OSP compatible applications. @n
102 * For more information, see @ref CompAudioContentInfoConstructPage "here".
105 * @return An error code
106 * @param[in] pContentPath The content path @n
107 * The path should be started with the directory path returned by
108 * either Tizen::System::Environment::GetMediaPath() or Tizen::System::Environment::GetExternalStoragePath(). @n
109 * If the path is @c null,
110 * use ContentManager::CreateContent(const Tizen::Base::ByteBuffer&, const Tizen::Base::String&, const ContentInfo*) @n
111 * or ContentManager::CreateContent(const Tizen::Base::String&, const Tizen::Base::String&, bool, const ContentInfo*),
112 * instead of this method.
113 * @exception E_SUCCESS The method is successful.
114 * @exception E_FILE_NOT_FOUND The specified file cannot be found or accessed.
115 * @exception E_INVALID_ARG The specified input parameter is invalid.
116 * @exception E_OUT_OF_MEMORY The memory is insufficient.
117 * @exception E_IO An I/O error has occurred.
118 * @exception E_SYSTEM An internal error has occurred.

125 * @section CompAudioContentInfoConstructPageIssueSection Issues
126 * The content path argument of this method in OSP compatible applications has the following issues: @n
127 * -# The content path should be a path that begins with an allowed path prefix. @n
128 * For example, L"/Media/Images/flower.jpg", L"/Storagecard/Media/Images/flower.jpg".
130 * @section CompAudioContentInfoConstructPageSolutionSection Resolutions
131 * This issue has been resolved in Tizen. @n
132 * -# The content path can be a path without a specific allowed path prefix. @n
133 * Application do not need to know the specific allowed path prefixes. @n
134 * To get the directory path, use the following methods: @n
135 * - For accessing the media directory, use Tizen::System::Environment::GetMediaPath().
136 * - For accessing the external storage, use Tizen::System::Environment::GetExternalStoragePath().
143 * Initializes this instance of %AudioContentInfo with the specified parameters.
145 * @brief <i> [Deprecated] </i>
146 * @deprecated This method is deprecated as there is a problem in managing the user-defined thumbnail and device coordinates. @n
147 * Instead of using this method, use Construct(const Tizen::Base::String*). @n
148 * To set the coordinates of the ContentInfo instance, use ContentInfo::SetCoordinates(const Tizen::Locations::Coordinates&).
151 * @return An error code
152 * @param[in] contentPath The content path
153 * @param[in] thumbnailPath The thumbnail path
154 * @param[in] setGps Set to @c true to save the device's last known coordinates of the ContentInfo instance, @n
156 * The coordinate information may be incorrect if it is outdated or has never been updated. @n
157 * To update the coordinate information or to get the exact value,
158 * use Tizen::Locations::LocationProvider::RequestLocationUpdates() before calling this method.
159 * @exception E_SUCCESS The method is successful.
160 * @exception E_FILE_NOT_FOUND The specified file cannot be found or accessed.
161 * @exception E_INVALID_ARG The specified input parameter is invalid.
162 * @exception E_OUT_OF_MEMORY The memory is insufficient.
163 * @exception E_IO An I/O error has occurred.
165 * - The content path must start with @c '/Media' or @c '/Storagecard/Media'.
166 * - The thumbnail path must start with @c '/Home', @c '/Media', or @c '/Storagecard/Media'. @n
167 * - The permitted format for a thumbnail image is bitmap (bmp).
