Constructor & Destructor Documentation

TimeArrayTimeZoneRule::TimeArrayTimeZoneRule (  const UnicodeString &  name,
int32_t  rawOffset,
int32_t  dstSavings,
const UDate *  startTimes,
int32_t  numStartTimes,

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.

Member Function Documentation

virtual TimeArrayTimeZoneRule* TimeArrayTimeZoneRule::clone (  void   )  const [virtual]
 

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 TimeZoneRule.

int32_t TimeArrayTimeZoneRule::countStartTimes (  void   )  const
 

Returns the number of start times stored in this rule.

Returns:
The number of start times.
Stable:
ICU 3.8

virtual UClassID TimeArrayTimeZoneRule::getDynamicClassID (  void   )  const [virtual]
 

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

Implements UObject.

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

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.
Stable:
ICU 3.8

Implements TimeZoneRule.

virtual UBool TimeArrayTimeZoneRule::getFirstStart (  int32_t  prevRawOffset,
int32_t  prevDSTSavings,
UDate &  result
)  const [virtual]
 

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.
Stable:
ICU 3.8

Implements TimeZoneRule.

virtual UBool TimeArrayTimeZoneRule::getNextStart (  UDate  base,
int32_t  prevRawOffset,
int32_t  prevDSTSavings,
UBool  inclusive,
UDate &  result
)  const [virtual]
 

Gets the first time when this rule takes effect after the specified time.

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

)  const [virtual]
 

Gets the most recent time when this rule takes effect before the specified time.

Parameters:
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 TimeZoneRule.

UBool TimeArrayTimeZoneRule::getStartTimeAt (  int32_t  index,
UDate &  result
)  const
 

Gets a start time at the index stored in this rule.

Parameters:
index The index of start times
result Receives the start time at the index
Returns:
true if the index is within the valid range and and the result is set. When false, the output parameger "result" is unchanged.
Stable:
ICU 3.8

UClassID TimeArrayTimeZoneRule::getStaticClassID (  void   )  [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()) ...
Returns:
The class ID for all objects of this class.

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.

Returns:
The time type used of the start times used by this rule.
Stable:
ICU 3.8

virtual UBool TimeArrayTimeZoneRule::isEquivalentTo (  const TimeZoneRule &  that  )  const [virtual]
 

Returns if this rule represents the same rule and offsets as another.

When two TimeZoneRule objects differ only its names, this method returns true.

Parameters:
that The TimeZoneRule object to be compared with.
Returns:
true if the other TimeZoneRule is equivalent to this one.
Stable:
ICU 3.8
