Detailed Description

An immutable class containing the result of a relative datetime formatting operation.

Instances of this class are immutable and thread-safe.

Not intended for public subclassing.

Stable:: ICU 64

Definition at line 274 of file reldatefmt.h.

Constructor & Destructor Documentation

◆ FormattedRelativeDateTime() [1/2]

icu::FormattedRelativeDateTime::FormattedRelativeDateTime ( )

inline

Default constructor; makes an empty FormattedRelativeDateTime.

Stable:: ICU 64

Definition at line 280 of file reldatefmt.h.

◆ FormattedRelativeDateTime() [2/2]

icu::FormattedRelativeDateTime::FormattedRelativeDateTime ( FormattedRelativeDateTime && src )

Move constructor: Leaves the source FormattedRelativeDateTime in an undefined state.

Stable:: ICU 64

◆ ~FormattedRelativeDateTime()

virtual icu::FormattedRelativeDateTime::~FormattedRelativeDateTime ( )

virtual

Destruct an instance of FormattedRelativeDateTime.

Stable:: ICU 64

Member Function Documentation

◆ appendTo()

Appendable & icu::FormattedRelativeDateTime::appendTo	(	Appendable &	appendable,
		UErrorCode &	status
	)		const

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.

Stable:: ICU 64

See also: Appendable

Implements icu::FormattedValue.

◆ nextPosition()

UBool icu::FormattedRelativeDateTime::nextPosition	(	ConstrainedFieldPosition &	cfpos,
		UErrorCode &	status
	)		const

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.

Stable:: ICU 64

Implements icu::FormattedValue.

◆ operator=()

FormattedRelativeDateTime & icu::FormattedRelativeDateTime::operator= ( FormattedRelativeDateTime && src )

Move assignment: Leaves the source FormattedRelativeDateTime in an undefined state.

Stable:: ICU 64

◆ toString()

UnicodeString icu::FormattedRelativeDateTime::toString ( UErrorCode & status ) const

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.

Stable:: ICU 64

Implements icu::FormattedValue.

◆ toTempString()

UnicodeString icu::FormattedRelativeDateTime::toTempString ( UErrorCode & status ) const

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.

Stable:: ICU 64

Implements icu::FormattedValue.
