| icu::InitialTimeZoneRule::InitialTimeZoneRule | ( | const UnicodeString & | name, |
| int32_t | rawOffset, | ||
| int32_t | dstSavings | ||
| ) |
Constructs an InitialTimeZoneRule with the name, the GMT offset of its standard time and the amount of daylight saving offset adjustment.
| 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. |
| icu::InitialTimeZoneRule::InitialTimeZoneRule | ( | const InitialTimeZoneRule & | source | ) |
|
virtual |
Destructor.
|
overridevirtual |
Clone this InitialTimeZoneRule object polymorphically.
The caller owns the result and should delete it when done.
Implements icu::TimeZoneRule.
|
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.
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.
|
static |
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()) ...
|
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.
| that | The object to be compared with. |
TimeZoneRule objects are semantically unequal. Reimplemented from icu::TimeZoneRule.
| InitialTimeZoneRule& icu::InitialTimeZoneRule::operator= | ( | const InitialTimeZoneRule & | right | ) |
|
overridevirtual |
Return true if the given TimeZoneRule objects are semantically equal.
Objects of different subclasses are considered unequal.
| that | The object to be compared with. |
TimeZoneRule objects are semantically equal. Reimplemented from icu::TimeZoneRule.
