◆ FormattedRelativeDateTime() [2/3]
| icu::FormattedRelativeDateTime::FormattedRelativeDateTime | ( | FormattedRelativeDateTime && | src | ) |
Move constructor: Leaves the source FormattedRelativeDateTime in an undefined state.
- Draft:
- This API may be changed in the future versions and was introduced in ICU 64
◆ ~FormattedRelativeDateTime()
|
virtual |
Destruct an instance of FormattedRelativeDateTime.

Member Function Documentation
◆ appendTo()
|
virtual |
Appends the formatted string to an Appendable.
- Parameters
-
appendable The Appendable to which to append the string output. status Set if an error occurs.
- Returns
- The same Appendable, for chaining.
- Draft:
- This API may be changed in the future versions and was introduced in ICU 64

Implements icu::FormattedValue.
◆ nextPosition()
|
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
-
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.

◆ operator=() [1/2]
|
delete |
Copying not supported; use move assignment instead.
◆ operator=() [2/2]
| FormattedRelativeDateTime& icu::FormattedRelativeDateTime::operator= | ( | FormattedRelativeDateTime && | src | ) |
Move assignment: Leaves the source FormattedRelativeDateTime in an undefined state.

◆ toString()
|
virtual |
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.
- Draft:
- This API may be changed in the future versions and was introduced in ICU 64
Implements icu::FormattedValue.
◆ toTempString()
|
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
-
status Set if an error occurs.
- Returns
- a temporary UnicodeString containing the formatted string.
