Constructor & Destructor Documentation

◆ TimeArrayTimeZoneRule() [1/2]

icu::TimeArrayTimeZoneRule::TimeArrayTimeZoneRule	(	const UnicodeString &	name,
		int32_t	rawOffset,
		int32_t	dstSavings,
		const UDate *	startTimes,
		int32_t	numStartTimes,
		DateTimeRule::TimeRuleType	timeRuleType
	)

Constructs a TimeArrayTimeZoneRule with the name, the GMT offset of its standard time, the amount of daylight saving offset adjustment and the array of times when this rule takes effect.

Parameters

name	The time zone name.
rawOffset	The UTC offset of its standard time in milliseconds.
dstSavings	The amount of daylight saving offset adjustment in milliseconds. If this ia a rule for standard time, the value of this argument is 0.
startTimes	The array start times in milliseconds since the base time (January 1, 1970, 00:00:00).
numStartTimes	The number of elements in the parameter "startTimes"
timeRuleType	The time type of the start times, which is one of `DataTimeRule::WALL_TIME`, `STANDARD_TIME` and `UTC_TIME`.

Stable:: ICU 3.8

◆ TimeArrayTimeZoneRule() [2/2]

icu::TimeArrayTimeZoneRule::TimeArrayTimeZoneRule ( const TimeArrayTimeZoneRule & source )

Copy constructor.

Parameters

source The TimeArrayTimeZoneRule object to be copied.

Stable:: ICU 3.8

◆ ~TimeArrayTimeZoneRule()

virtual icu::TimeArrayTimeZoneRule::~TimeArrayTimeZoneRule ( )

virtual

Destructor.

Member Function Documentation

◆ clone()

virtual TimeArrayTimeZoneRule * icu::TimeArrayTimeZoneRule::clone ( ) const

overridevirtual

Clone this TimeArrayTimeZoneRule object polymorphically.

The caller owns the result and should delete it when done.

Returns: A copy of the object.

Stable:: ICU 3.8

Implements icu::TimeZoneRule.

◆ countStartTimes()

int32_t icu::TimeArrayTimeZoneRule::countStartTimes ( void ) const

Returns the number of start times stored in this rule.

Returns: The number of start times.

Stable:: ICU 3.8

◆ getDynamicClassID()

virtual UClassID icu::TimeArrayTimeZoneRule::getDynamicClassID ( void ) const

overridevirtual

Returns a unique class ID POLYMORPHICALLY.

Pure virtual override. This method is to implement a simple version of RTTI, since not all C++ compilers support genuine RTTI. Polymorphic operator==() and clone() methods call this method.

Returns: The class ID for this object. All objects of a given class have the same class ID. Objects of other classes have different class IDs.

Stable:: ICU 3.8

Reimplemented from icu::UObject.

◆ getFinalStart()

virtual UBool icu::TimeArrayTimeZoneRule::getFinalStart	(	int32_t	prevRawOffset,
		int32_t	prevDSTSavings,
		UDate &	result
	)		const

overridevirtual

Gets the final time when this rule takes effect.

Parameters

prevRawOffset	The standard time offset from UTC before this rule takes effect in milliseconds.
prevDSTSavings	The amount of daylight saving offset from the standard time.
result	Receives the final time when this rule takes effect.

Returns: true if the start time is available. When false is returned, output parameter "result" is unchanged.

◆ getFirstStart()

virtual UBool icu::TimeArrayTimeZoneRule::getFirstStart	(	int32_t	prevRawOffset,
		int32_t	prevDSTSavings,

overridevirtual

Gets the very first time when this rule takes effect.

Parameters

prevRawOffset	The standard time offset from UTC before this rule takes effect in milliseconds.
prevDSTSavings	The amount of daylight saving offset from the standard time.
result	Receives the very first time when this rule takes effect.

Returns: true if the start time is available. When false is returned, output parameter "result" is unchanged.

Implements icu::TimeZoneRule.

◆ getNextStart()

virtual UBool icu::TimeArrayTimeZoneRule::getNextStart	(	UDate	base,
