5 | * Descr : We do a standard differential |
---|
6 | * change detection by sorting both |
---|
7 | * lists of items by their unique id, |
---|
8 | * and then traversing both arrays |
---|
9 | * of items at once. Changes can be |
---|
10 | * detected by comparing items at |
---|
11 | * the same position in both arrays. |
