C++ API: ICU TimeZone base class.
BasicTimeZone is an abstract class extending TimeZone.
InitialTimeZoneRule represents a time zone rule representing a time zone effective from the beginning...
"Smart pointer" base class; do not use directly: use LocalPointer etc.
a BasicTimeZone subclass implemented in terms of InitialTimeZoneRule and TimeZoneRule instances
virtual ~RuleBasedTimeZone()
Destructor.
virtual UBool useDaylightTime(void) const override
Queries if this time zone uses daylight savings time.
virtual int32_t countTransitionRules(UErrorCode &status) const override
Returns the number of TimeZoneRules which represents time transitions, for this time zone,...
virtual UBool getPreviousTransition(UDate base, UBool inclusive, TimeZoneTransition &result) const override
Gets the most recent time zone transition before the base time.
void complete(UErrorCode &status)
Makes the TimeZoneRule ready to handle actual timezone calculation APIs.
virtual int32_t getOffset(uint8_t era, int32_t year, int32_t month, int32_t day, uint8_t dayOfWeek, int32_t millis, int32_t monthLength, UErrorCode &status) const override
Gets the time zone offset, for current date, modified in case of daylight savings.

virtual int32_t getOffset(uint8_t era, int32_t year, int32_t month, int32_t day, uint8_t dayOfWeek, int32_t millis, UErrorCode &status) const override
Returns the TimeZone's adjusted GMT offset (i.e., the number of milliseconds to add to GMT to get loc...
virtual void setRawOffset(int32_t offsetMillis) override
Sets the TimeZone's raw GMT offset (i.e., the number of milliseconds to add to GMT to get local time,...
virtual int32_t getRawOffset(void) const override
Returns the TimeZone's raw GMT offset (i.e., the number of milliseconds to add to GMT to get local ti...
virtual void getTimeZoneRules(const InitialTimeZoneRule *&initial, const TimeZoneRule *trsrules[], int32_t &trscount, UErrorCode &status) const override
Gets the InitialTimeZoneRule and the set of TimeZoneRule which represent time transitions for this ti...
virtual void getOffset(UDate date, UBool local, int32_t &rawOffset, int32_t &dstOffset, UErrorCode &ec) const override
Returns the time zone raw and GMT offset for the given moment in time.
void addTransitionRule(TimeZoneRule *rule, UErrorCode &status)
Adds the TimeZoneRule which represents time transitions.
virtual UBool getNextTransition(UDate base, UBool inclusive, TimeZoneTransition &result) const override
Gets the first time zone transition after the base time.
virtual UClassID getDynamicClassID(void) const override
Returns a unique class ID POLYMORPHICALLY.

static UClassID getStaticClassID(void)
Return the class ID for this class.
RuleBasedTimeZone & operator=(const RuleBasedTimeZone &right)
Assignment operator.
virtual UBool hasSameRules(const TimeZone &other) const override
