Implemented in icu::FormattedRelativeDateTime, icu::number::FormattedNumberRange, icu::message2::FormattedMessage, icu::FormattedList, icu::number::FormattedNumber, and icu::FormattedDateInterval.

Iterates over field positions in the FormattedValue.

This lets you determine the position of specific types of substrings, like a month or a decimal separator.

To loop over all field positions:

ConstrainedFieldPosition cfpos;
while (fmtval.nextPosition(cfpos, status)) {
    // handle the field position; get information from cfpos
}

Parameters

cfpos	The object used for iteration state. This can provide constraints to iterate over only one specific category or field; see ConstrainedFieldPosition::constrainCategory and ConstrainedFieldPosition::constrainField.
status	Set if an error occurs.

Returns

true if a new occurrence of the field was found; false otherwise or if an error was set.

Implemented in icu::FormattedRelativeDateTime, icu::number::FormattedNumberRange, icu::message2::FormattedMessage, icu::FormattedList, icu::number::FormattedNumber, and icu::FormattedDateInterval.

Returns the formatted string as a self-contained UnicodeString.

If you need the string within the current scope only, consider toTempString.

Parameters

status

Set if an error occurs.

Returns

a UnicodeString containing the formatted string.

Implemented in icu::FormattedRelativeDateTime, icu::number::FormattedNumberRange, icu::message2::FormattedMessage, icu::FormattedList, icu::number::FormattedNumber, and icu::FormattedDateInterval.

Returns the formatted string as a read-only alias to memory owned by the FormattedValue.

The return value is valid only as long as this FormattedValue is present and unchanged in memory. If you need the string outside the current scope, consider toString.

The buffer returned by calling UnicodeString::getBuffer() on the return value is guaranteed to be NUL-terminated.

Parameters

status

Set if an error occurs.

Returns

a temporary UnicodeString containing the formatted string.
