Detailed Description

An abstract formatted value: a string with associated field attributes.

Many formatters format to classes implementing FormattedValue.

◆ appendTo()

virtual Appendable& icu::FormattedValue::appendTo ( Appendable appendable,
UErrorCode status 
) const
pure virtual

Appends the formatted string to an Appendable.

Parameters
appendableThe Appendable to which to append the string output.
statusSet if an error occurs.
Returns
The same Appendable, for chaining.

ICU 64

Appendable

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

◆ nextPosition()

virtual UBool icu::FormattedValue::nextPosition ( ConstrainedFieldPosition cfpos,
UErrorCode status 
) const
pure virtual

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
cfposThe object used for iteration state. This can provide constraints to iterate over only one specific category or field; see ConstrainedFieldPosition::constrainCategory and ConstrainedFieldPosition::constrainField.
statusSet if an error occurs.
Returns
true if a new occurrence of the field was found; false otherwise or if an error was set.
Stable:
ICU 64

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

◆ toString()

virtual UnicodeString icu::FormattedValue::toString ( UErrorCode status) const
pure virtual

Returns the formatted string as a self-contained UnicodeString.

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

Parameters
statusSet if an error occurs.
Returns
a UnicodeString containing the formatted string.
Stable:
ICU 64

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

◆ toTempString()

virtual UnicodeString icu::FormattedValue::toTempString ( UErrorCode status) const
pure virtual

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
statusSet if an error occurs.
Returns
a temporary UnicodeString containing the formatted string.
Stable:
ICU 64

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