TimeZoneTransition
is a class representing a time zone transition.
An instance has a time of transition and rules for both before and after the transition.
Definition at line 31 of file tztrans.h.
TimeZoneTransition::TimeZoneTransition | ( | UDate | time, | |
const TimeZoneRule & | from, | |||
const TimeZoneRule & | to | |||
) |
Constructs a TimeZoneTransition
with the time and the rules before/after the transition.
time | The time of transition in milliseconds since the base time. | |
from | The time zone rule used before the transition. | |
to | The time zone rule used after the transition. |
TimeZoneTransition::TimeZoneTransition | ( | ) |
Constructs an empty TimeZoneTransition
.
TimeZoneTransition::TimeZoneTransition | ( | const TimeZoneTransition & | source | ) |
TimeZoneTransition::~TimeZoneTransition | ( | ) |
Destructor.
void TimeZoneTransition::adoptFrom | ( | TimeZoneRule * | from | ) |
Adopts the rule used before the transition.
The caller must not delete the TimeZoneRule
object passed in.
from | The time zone rule used before the transition. |
void TimeZoneTransition::adoptTo | ( | TimeZoneRule * | to | ) |
Adopts the rule used after the transition.
The caller must not delete the TimeZoneRule
object passed in.
to | The time zone rule used after the transition. |
TimeZoneTransition* TimeZoneTransition::clone | ( | void | ) | const |
Clone this TimeZoneTransition object polymorphically.
The caller owns the result and should delete it when done.
virtual UClassID TimeZoneTransition::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.
Implements UObject.
const TimeZoneRule* TimeZoneTransition::getFrom | ( | void | ) | const |
Returns the rule used before the transition.
static UClassID TimeZoneTransition::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()) ...
UDate TimeZoneTransition::getTime | ( | void | ) | const |
Returns the time of transition in milliseconds.
const TimeZoneRule* TimeZoneTransition::getTo | ( | void | ) | const |
Returns the rule used after the transition.
UBool TimeZoneTransition::operator!= | ( | const TimeZoneTransition & | that | ) | const |
Return true if the given TimeZoneTransition objects are semantically unequal.
Objects of different subclasses are considered unequal.
that | The object to be compared with. |
TimeZoneTransition& TimeZoneTransition::operator= | ( | const TimeZoneTransition & | right | ) |
UBool TimeZoneTransition::operator== | ( | const TimeZoneTransition & | that | ) | const |
Return true if the given TimeZoneTransition objects are semantically equal.
Objects of different subclasses are considered unequal.
that | The object to be compared with. |
void TimeZoneTransition::setFrom | ( | const TimeZoneRule & | from | ) |
Sets the rule used before the transition.
The caller remains responsible for deleting the TimeZoneRule
object.
from | The time zone rule used before the transition. |
void TimeZoneTransition::setTime | ( | UDate | time | ) |
Sets the time of transition in milliseconds.
time | The time of the transition in milliseconds since the 1970 Jan 1 epoch time. |
void TimeZoneTransition::setTo | ( | const TimeZoneRule & | to | ) |
Sets the rule used after the transition.
The caller remains responsible for deleting the TimeZoneRule
object.
to | The time zone rule used after the transition. |
