| 549 | * solely for the purpose of avoiding to clone the array of strings | |
| 550 | * just to modify one of them and then setting all of them back. | |
| 551 | * For example, the old code looked like this: | |
| 552 | * case UDAT_MONTHS: | |
| 553 | * res = syms->getMonths(count); | |
| 554 | * array = new UnicodeString[count]; | |
| 555 | * if(array == 0) { | |

| 557 | * return; | |
| 558 | * } | |
| 559 | * uprv_arrayCopy(res, array, count); | |
| 560 | * if(index < count) | |
| 561 | * array[index] = val; | |
| 562 | * syms->setMonths(array, count); | |
| 563 | * break; | |
| 564 | * | |
| 565 | * Even worse, the old code actually cloned the entire DateFormatSymbols object, | |
| 566 | * cloned one value array, changed one value, and then made the SimpleDateFormat | |
| 567 | * replace its DateFormatSymbols object with the new one. | |
