Detailed Description

TimeZoneFormat supports time zone display name formatting and parsing.

An instance of TimeZoneFormat works as a subformatter of SimpleDateFormat, but you can also directly get a new instance of TimeZoneFormat and formatting/parsing time zone display names.

ICU implements the time zone display names defined by UTS#35 Unicode Locale Data Markup Language (LDML). TimeZoneNames represents the time zone display name data model and this class implements the algorithm for actual formatting and parsing.

◆ format() [1/5]

virtual UnicodeString & icu::TimeZoneFormat::format ( const Formattable obj,
UnicodeString appendTo,
FieldPosition pos,
UErrorCode status 
) const
overridevirtual

Format an object to produce a time zone display string using localized GMT offset format.

This method handles Formattable objects with a TimeZone. If a the Formattable object type is not a TimeZone, then it returns a failing UErrorCode.

Parameters
objThe object to format. Must be a TimeZone.
appendToOutput parameter to receive result. Result is appended to existing contents.
posOn input: an alignment field, if desired. On output: the offsets of the alignment field.
statusOutput param filled with success/failure status.

Implements icu::Format.

◆ format() [2/5]

virtual UnicodeString & icu::Format::format ( const Formattable obj,
UnicodeString appendTo,
FieldPosition pos,
UErrorCode status 
) const
virtual

Format an object to produce a string.

This is a pure virtual method which subclasses must implement. This method allows polymorphic formatting of Formattable objects. If a subclass of Format receives a Formattable object type it doesn't handle (e.g., if a numeric Formattable is passed to a DateFormat object) then it returns a failing UErrorCode.

Parameters
objThe object to format.
appendToOutput parameter to receive result. Result is appended to existing contents.
posOn input: an alignment field, if desired. On output: the offsets of the alignment field.
statusOutput param filled with success/failure status.

virtual

Format an object to produce a string.

Subclasses should override this method. This method allows polymorphic formatting of Formattable objects. If a subclass of Format receives a Formattable object type it doesn't handle (e.g., if a numeric Formattable is passed to a DateFormat object) then it returns a failing UErrorCode.

Parameters
objThe object to format.
appendToOutput parameter to receive result. Result is appended to existing contents.
posIterOn return, can be used to iterate over positions of fields generated by this format call.
statusOutput param filled with success/failure status.
