37 * @brief This class provides methods to manipulate in-memory table.
41 * @final This class is not intended for extension.
43 * The %DataSet class provides methods to manipulate in-memory table.
45 class _OSP_EXPORT_ DataSet
46 : public Tizen::Base::Object
51 * The object is not fully constructed after this constructor is called. For full construction,
52 * the Construct() method must be called right after calling this constructor.
59 * This destructor overrides Tizen::Base::Object::~Object().
63 virtual ~DataSet(void);
66 * Creates in-memory table.
70 * @return An error code
71 * @param[in] columnNames The list of column names to create @n
72 * The object type in the specified list should be String.
73 * @exception E_SUCCESS The method is successful.
74 * @exception E_INVALID_ARG The specified @c columnNames has no element.
76 result Construct(const Tizen::Base::Collection::IList& columnNames);
79 * Creates a row in the table.
83 * @return A pointer to the DataRow instance, @n
84 * else @c null if the memory is insufficient
85 * @remarks The column type is decided by the type of each element inserted in first row.
86 * If a specific column element on the first row is not inserted, then the column's type is @c DB_COLUMNTYPE_NULL
87 * In that case, when a new column element is added later,
88 * then the column's type will be changed according to the new element.

120 * instance of %DataSet, @n
