Detailed Description

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.

Stable:

ICU 3.8

Definition at line 31 of file tztrans.h.

Constructor & Destructor Documentation

icu::TimeZoneTransition::TimeZoneTransition	(	UDate	time,
		const TimeZoneRule &	from,
		const TimeZoneRule &	to
	)

Constructs a TimeZoneTransition with the time and the rules before/after the transition.

Parameters

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.

Stable:

ICU 3.8

icu::TimeZoneTransition::TimeZoneTransition

(

)

Constructs an empty TimeZoneTransition

Stable:

ICU 3.8

icu::TimeZoneTransition::TimeZoneTransition

(

const TimeZoneTransition &

source

)

Copy constructor.

Parameters

source

The TimeZoneTransition object to be copied.

Stable:

ICU 3.8

icu::TimeZoneTransition::~TimeZoneTransition

(

)

Destructor.

Stable:

ICU 3.8

Member Function Documentation

void icu::TimeZoneTransition::adoptFrom

(

TimeZoneRule *

from

)

Adopts the rule used before the transition.

The caller must not delete the TimeZoneRule object passed in.

Parameters

from	The time zone rule used before the transition.

Stable:

ICU 3.8

void icu::TimeZoneTransition::adoptTo

(

TimeZoneRule *

to

)

Adopts the rule used after the transition.

The caller must not delete the TimeZoneRule object passed in.

Parameters

to	The time zone rule used after the transition.

Stable:

ICU 3.8

TimeZoneTransition* icu::TimeZoneTransition::clone

(

void

)

const

Clone this TimeZoneTransition object polymorphically.

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

Returns

A copy of the object.

Stable:

ICU 3.8

virtual UClassID icu::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.

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.

const TimeZoneRule* icu::TimeZoneTransition::getFrom

(

void

)

const

Returns the rule used before the transition.

Returns

The time zone rule used after the transition.

Stable:

ICU 3.8

static UClassID icu::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()) ...

Returns

The class ID for all objects of this class.

Stable:

ICU 3.8

UDate icu::TimeZoneTransition::getTime

(

void

)

const

Returns the time of transition in milliseconds.

Returns

The time of the transition in milliseconds since the 1970 Jan 1 epoch time.

Stable:

ICU 3.8

const TimeZoneRule* icu::TimeZoneTransition::getTo

(

void

)

const

Returns the rule used after the transition.

Returns

The time zone rule used after the transition.

Stable:

ICU 3.8

UBool icu::TimeZoneTransition::operator!=

(

const TimeZoneTransition &

that

)

const

Return true if the given TimeZoneTransition objects are semantically unequal.

Objects of different subclasses are considered unequal.

Parameters

that	The object to be compared with.

Returns

true if the given TimeZoneTransition objects are semantically unequal.

Stable:

ICU 3.8

TimeZoneTransition& icu::TimeZoneTransition::operator=

(

const TimeZoneTransition &

right

)

Assignment operator.

Parameters

right

The object to be copied.

Stable:

ICU 3.8

UBool icu::TimeZoneTransition::operator==

(

const TimeZoneTransition &

that

)

const

Return true if the given TimeZoneTransition objects are semantically equal.

Objects of different subclasses are considered unequal.

Parameters

that	The object to be compared with.

Returns

true if the given TimeZoneTransition objects are semantically equal.

Stable:

ICU 3.8

void icu::TimeZoneTransition::setFrom

(

const TimeZoneRule &

from

)

Sets the rule used before the transition.

The caller remains responsible for deleting the TimeZoneRule object.

Parameters

from	The time zone rule used before the transition.

Stable:

ICU 3.8

void icu::TimeZoneTransition::setTime

(

UDate

time

)

Sets the time of transition in milliseconds.

Parameters

time	The time of the transition in milliseconds since the 1970 Jan 1 epoch time.

Stable:

ICU 3.8

void icu::TimeZoneTransition::setTo

(

const TimeZoneRule &

to

)

Sets the rule used after the transition.

The caller remains responsible for deleting the TimeZoneRule object.

Parameters

to	The time zone rule used after the transition.
