| 2 | mixed *transpose_array (mixed *arr); |
| 3 | |
| 4 | DESCRIPTION: |
| 5 | transpose_array ( ({ ({1,2,3}), ({a,b,c}) }) ) |
| 6 | == ({ ({1,a}), ({2,b)}, ({3,c}) }) |
| 7 | |
| 8 | transpose_array() applied to an alist results in an array of |
| 9 | ({ key, data }) pairs, useful if you want to use sort_array() |
| 10 | or filter() on the alist. |
| 11 | |
| 12 | EXAMPLE: |
| 13 | sort_array(transpose_array( ({ m_indices(map), m_values(map) }) ), |
| 14 | lambda( ({ 'a, 'b }), |
| 15 | ({ #'<, ({ #'[, 'a, 0 }), |
| 16 | ({ #'[, 'b, 0}) }) ) ) |
| 17 | |
| 18 | The given mapping 'map' is returned as an array of |
| 19 | ({ key, data }) pairs, sorted by the keys. |
