get a const ptr to the data from column _ci in row _ri.second of table _ri.first. The data stored in the column must be of type _TR. In this function no data copying is done. Note that this function returns a pointer to the columns raw data, so it can only be used to refer to constant columns.

get a const pointer to the data from column _ci in row _ri of table _ti. The data stored in the column must be of type _TR. This only works if the column's data is constant. There is no implicit copying performed.

clone operation clone destructor return the column information for column _C_n. the return value is a reference to the type_info of the column's value type. The reference _r contains upon returning whether the function was successful, the column id, and the column flags. return a reference to the type_info of the column's value type. insert a new row of specification _row into the table, and return the row id of the newly created row in _r. The function returns true, if inserting was successful. remove the row with it _ri from the table return whether the column _C_n is defined in the table return table id and column id of column _C_n return column name of column _C_n return a const reference to the column with column id _ci in row _ri.second of table ri.first. If successful, set error to false, and to true otherwise. Note that in this function the context for the column is NOT set. This method adds the row ids in _rs to the visible part of the view. This method removes the row ids in _rs from the visible part of the view. print the contents of the column with column id _ci in row _ri.second of table ri.first. If the row is empty and no default is defined, print nothing. return a const reference to the row with row id _ri.second of table ri.first. If successful, set error to false, and to true otherwise. return a const reference to the default column with column id _ri.second of table ri.first. If successful, set error to false, and to true otherwise. return iterator to first default column return iterator beyond last default column return iterator to first row return iterator beyond last row return iterator to first column return iterator beyond last column return the type of this view
