TimeZoneRule is a class representing a rule for time zone.
Definition: tzrule.h:36
TimeZoneTransition is a class representing a time zone transition.
Definition: tztrans.h:35
TimeZoneTransition(UDate time, const TimeZoneRule &from, const TimeZoneRule &to)
Constructs a TimeZoneTransition with the time and the rules before/after the transition.
const TimeZoneRule * getFrom(void) const
Returns the rule used before the transition.
const TimeZoneRule * getTo(void) const
Returns the rule used after the transition.
TimeZoneTransition()
Constructs an empty TimeZoneTransition
void setTo(const TimeZoneRule &to)
Sets the rule used after the transition.
void setFrom(const TimeZoneRule &from)
Sets the rule used before the transition.
TimeZoneTransition & operator=(const TimeZoneTransition &right)
Assignment operator.
TimeZoneTransition(const TimeZoneTransition &source)
Copy constructor.
UDate getTime(void) const
Returns the time of transition in milliseconds.
TimeZoneTransition * clone() const
Clone this TimeZoneTransition object polymorphically.
void adoptTo(TimeZoneRule *to)
Adopts the rule used after the transition.
virtual UClassID getDynamicClassID(void) const override
Returns a unique class ID POLYMORPHICALLY.
void adoptFrom(TimeZoneRule *from)
Adopts the rule used before the transition.
void setTime(UDate time)
Sets the time of transition in milliseconds.
bool operator==(const TimeZoneTransition &that) const
Return true if the given TimeZoneTransition objects are semantically equal.
~TimeZoneTransition()
Destructor.
bool operator!=(const TimeZoneTransition &that) const
Return true if the given TimeZoneTransition objects are semantically unequal.
static UClassID getStaticClassID(void)
Return the class ID for this class.
UObject is the common ICU "boilerplate" class.
Definition: uobject.h:223
C++ API: Common ICU base class UObject.
void * UClassID
UClassID is used to identify classes without using the compiler's RTTI.
Definition: uobject.h:96
Basic definitions for ICU, for both C and C++ APIs.
#define U_I18N_API
Set to export library symbols from inside the i18n library, and to import them from outside.
Definition: utypes.h:301
double UDate
Date and Time data type.
Definition: utypes.h:203
