DataTable Logic With Columns, Rows & Cells (No GUI).

This should be an Xcode project done in C++ with STL dependency ONLY. The idea is to have the basic features of a DataTable with no GUI. Only requires logs to print out results of the method calls. Implementation details should be discussed beforehand. Performance is very important, so any implementation should always consider performance. The main classes would be: DataTable Column Row Cell The Column should be able to have these types of values: string; number; boolean; date & object. The DataTable contains the columns and rows. The methods that the DataTable should have are: // Adds a column at the end of any existing columns. AddColumn(type, name); //Inserts a new column to the data table, at the specifid index. All existing columns at or after the specified index are shifted to a higher index InsertColumn(columnIndex, type, name); RemoveColumn(columnIndex); // Adds row at end of rows AddRow([value, value, ..., value]); // Inserts row at specified row index InsertRow(rowIndex, [value, value, ..., value]); RemoveRow(rowIndex); //Returns an array of the unique values in a certain column, in ascending order. GetDistinctValuesFromColumn(columnIndex); // Returns the row indexes for rows that match all of the given filters // filters - An array of objects that describe an acceptable cell value GetFilteredRows(filters); // Returns the formatted value of the cell at the given row and column indexes. GetFormattedValue(rowIndex, columnIndex); // Returns a sorted version of the table without modifying the order of the underlying data. // sortColumns: array of column indexes to sort by GetSortedRows(sortColumns); SetValue(rowIndex, columnIndex, value);
