|
* This DateFormatSymbolsSingleSetter class is a friend of DateFormatSymbols
|
|
* solely for the purpose of avoiding to clone the array of strings
|
|
* just to modify one of them and then setting all of them back.
|
|
* For example, the old code looked like this:
|
|
* case UDAT_MONTHS:
|
|
* res = syms->getMonths(count);
|
|
* array = new UnicodeString[count];
|
|
* if(array == 0) {
|
|
* *status = U_MEMORY_ALLOCATION_ERROR;
|
|
* return;
|
|
* }
|
|
* uprv_arrayCopy(res, array, count);
|
|
* if(index < count)
|
|
* array[index] = val;
|
|
* syms->setMonths(array, count);
|
|
* break;
|
|
*
|
|
* Even worse, the old code actually cloned the entire DateFormatSymbols object,
|
|
* cloned one value array, changed one value, and then made the SimpleDateFormat
|
|
* replace its DateFormatSymbols object with the new one.
