Iterates over each of the cells in CXlOper instances that contain arrays.
class CXlArrayCellIterator<T> |
The CXlArrayCellIterator<T> class is a utility class to help you iterate across CXlOper instances that contain large arrays. The iterator traverses across all cells in the array row-wise, starting at the top row and moving to the bottom row. Within each row it traverses from left to right.
The class is normally accessed through a typedef of the container class: CXlArrayContainer<T>::cell_iterator
.
These iterators can be used to iterate through a CXlOper containing an array with minimum performance overhead. Compared with standard CXlOper programming, using these classes is harder work.
Use the class with the following pattern:
double total = 0.0; if (input->HasOper12()) { CXlArrayContainer<XLOPER12> cont(*input); for (CXlArrayContainer<XLOPER12>::cell_iterator i = cont.begin(); i != cont.end(); i++) { // Look at the value in each cell if (i->xltype == xltypeNum) total += i->val.num; } } else if (input->HasOper4()) { // Provide this section only if you wish to provide support for Excel 2003 and below CXlArrayContainer<XLOPER4> cont(*input); // ... }
