class row_handle
row_handle is the way to access data stored in rows
Public Functions
-
inline bool empty() const
Return true if the row is empty or uninitialised.
-
inline item_handle operator[](uint16_t column_ix)
return a cif::item_handle to the item in column column_ix
-
inline const item_handle operator[](uint16_t column_ix) const
return a const cif::item_handle to the item in column column_ix
-
inline item_handle operator[](std::string_view column_name)
return a cif::item_handle to the item in the column named column_name
-
inline const item_handle operator[](std::string_view column_name) const
return a const cif::item_handle to the item in the column named column_name
-
template<typename ...C>
inline auto get(C... columns) const Return an object that can be used in combination with cif::tie to assign the values for the columns columns.
-
template<typename ...Ts, typename ...C, std::enable_if_t<sizeof...(Ts) == sizeof...(C) and sizeof...(C) != 1, int> = 0>
inline std::tuple<Ts...> get(C... columns) const Return a tuple of values of types Ts for the columns columns.
-
template<typename T>
inline T get(const char *column) const Get the value of column column cast to type T.
-
inline void assign(const std::vector<item> &values)
assign each of the columns named in values to their respective value
-
inline void assign(std::string_view name, std::string_view value, bool updateLinked, bool validate = true)
assign the value value to the column named name
If updateLinked it true, linked records are updated as well. That means that if column name is part of the link definition and the link results in a linked record in another category this record in the linked category is updated as well.
If validate is true, which is default, the assigned value is checked to see if it conforms to the rules defined in the dictionary
-
void assign(uint16_t column, std::string_view value, bool updateLinked, bool validate = true)
assign the value value to column at index column
If updateLinked it true, linked records are updated as well. That means that if column column is part of the link definition and the link results in a linked record in another category this record in the linked category is updated as well.
If validate is true, which is default, the assigned value is checked to see if it conforms to the rules defined in the dictionary
-
inline bool operator==(const row_handle &rhs) const
compare two rows
-
inline bool operator!=(const row_handle &rhs) const
compare two rows
-
inline bool empty() const
