Implementsicu::Format.

Formats a plural message for a number taken from aFormattable object.

Parameters

obj	The object containing a number for which the plural message should be formatted. The object must be of a numeric type.
appendTo	output parameter to receive result. Result is appended to existing contents.
pos	On input: an alignment field, if desired. On output: the offsets of the alignment field.
status	output param filled with success/failure status.

Returns

Reference to 'appendTo' parameter.

ICU 4.0

Implementsicu::Format.

Format an object to produce a string.

This is a pure virtual method which subclasses must implement. This method allows polymorphic formatting ofFormattable objects. If a subclass ofFormat receives aFormattable object type it doesn't handle (e.g., if a numericFormattable is passed to aDateFormat object) then it returns a failing UErrorCode.

Parameters

obj	The object to format.
appendTo	Output parameter to receive result. Result is appended to existing contents.
pos	On input: an alignment field, if desired. On output: the offsets of the alignment field.
status	Output param filled with success/failure status.

Returns

Reference to 'appendTo' parameter.

Stable:

ICU 2.0

Format an object to produce a string.

Subclasses should override this method. This method allows polymorphic formatting ofFormattable objects. If a subclass ofFormat receives aFormattable object type it doesn't handle (e.g., if a numericFormattable is passed to aDateFormat object) then it returns a failing UErrorCode.

Parameters

obj	The object to format.
appendTo	Output parameter to receive result. Result is appended to existing contents.
posIter	On return, can be used to iterate over positions of fields generated by this format call.
status	Output param filled with success/failure status.

Returns

Reference to 'appendTo' parameter.

Stable:

ICU 4.4

Formats an object to produce a string.

Parameters

obj	The object to format.
appendTo	Output parameter to receive result. Result is appended to existing contents.
status	Output parameter filled in with success or failure status.

Returns

Reference to 'appendTo' parameter.

Stable:

ICU 2.0

Formats a plural message for a given number.

Parameters

Returns

the string containing the formatted plural message.

Stable:

Implementsicu::Format.

This method is not yet supported byPluralFormat.

Before calling, set parse_pos.index to the offset you want to start parsing at in the source. After calling, parse_pos.index is the end of the text you parsed. If error occurs, index is unchanged.

When parsing, leading whitespace is discarded (with a successful parse), while trailing whitespace is left as is.

SeeFormat::parseObject() for more.

Parameters

source	The string to be parsed into an object.
result	Formattable to be set to the parse result. If parse fails, return contents are undefined.
parse_pos	The position to start parsing at. Upon return this param is set to the position after the last character successfully parsed. If the source is not parsed successfully, this param will remain unchanged.

Stable:

ICU 4.0

Implementsicu::Format.

Sets the locale used by thisPluraFormat object.

Note: Calling this method resets thisPluraFormat object, i.e., a pattern that was applied previously will be removed, and theNumberFormat is set to the default number format for the locale. The resulting format behaves the same as one constructed fromPluralFormat(const Locale& locale, UPluralType type, UErrorCode& status) with UPLURAL_TYPE_CARDINAL.

Parameters

locale	thelocale to use to configure the formatter.
status	output param set to success/failure code on exit, which must not indicate a failure before the function call.

Deprecated:

ICU 50 This method clears the pattern and might create a different kind ofPluralRules instance; use one of the constructors to create a new instance instead.

Sets the number format used by this formatter.

You only need to call this if you want a different number format than the default formatter for the locale.

Parameters

format	the number format to use.
status	output param set to success/failure code on exit, which must not indicate a failure before the function call.

Stable:

ICU 4.0

Returns the pattern fromapplyPattern() or constructor().

Parameters

appendTo

output parameter to receive result. Result is appended to existing contents.

Returns

theUnicodeString with inserted pattern.
