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.
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 . |

overridevirtual |
Clone this TimeArrayTimeZoneRule object polymorphically.
The caller owns the result and should delete it when done.
Implements icu::TimeZoneRule.
int32_t icu::TimeArrayTimeZoneRule::countStartTimes | ( | ) | const |
Returns the number of start times stored in this rule.
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.
Reimplemented from icu::UObject.
|
overridevirtual |
Gets the final time when this rule takes effect.
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. |
Implements icu::TimeZoneRule.
|
overridevirtual |
Gets the very first time when this rule takes effect.
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. |
Implements icu::TimeZoneRule.
|
overridevirtual |
Gets the first time when this rule takes effect after the specified time.
base | The first start time after this base time will be returned. |
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. |
inclusive | Whether the base time is inclusive or not. |
result | Receives The first time when this rule takes effect after the specified base time. |
Implements icu::TimeZoneRule.
|
overridevirtual |
Gets the most recent time when this rule takes effect before the specified time.
base | The most recent time before this base time will be returned. |
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. |
inclusive | Whether the base time is inclusive or not. |
result | Receives The most recent time when this rule takes effect before the specified base time. |
Implements icu::TimeZoneRule.
Gets a start time at the index stored in this rule.
index | The index of start times |
result | Receives the start time at the index |
Return the class ID for this class.
This is useful only for comparing to a return value from getDynamicClassID(). For example:
. Base* polymorphic_pointer = createPolymorphicObject(); . if (polymorphic_pointer->getDynamicClassID() == . erived::getStaticClassID()) ...
DateTimeRule::TimeRuleType icu::TimeArrayTimeZoneRule::getTimeType | ( | ) | const |
Gets the time type of the start times used by this rule.
The return value is either DateTimeRule::WALL_TIME
or STANDARD_TIME
or UTC_TIME
.
|
overridevirtual |
Returns if this rule represents the same rule and offsets as another.
When two TimeZoneRule
objects differ only its names, this method returns true.
that | The TimeZoneRule object to be compared with. |
TimeZoneRule
is equivalent to this one. Reimplemented from icu::TimeZoneRule.
|
overridevirtual |
Return true if the given TimeZoneRule
objects are semantically unequal.
Objects of different subclasses are considered unequal.

TimeZoneRule
objects are semantically unequal. Reimplemented from icu::TimeZoneRule.
TimeArrayTimeZoneRule & icu::TimeArrayTimeZoneRule::operator= | ( | const TimeArrayTimeZoneRule & | right | ) |
|

Return true if the given TimeZoneRule
objects are semantically equal.
Objects of different subclasses are considered unequal.
