Implements TimeZone. |
|
Makes the This method collects time zone rules specified by the caller via the constructor and addTransitionRule() and builds internal structure for making the object ready to support time zone APIs such as getOffset(), getNextTransition() and others.
|
|
Returns the number of The return value range is 0 or any positive value.
Implements BasicTimeZone. |
|
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 TimeZone. |
|
Gets the first time zone transition after the base time.
Implements BasicTimeZone. |
|
Returns the time zone raw and GMT offset for the given moment in time. Upon return, local-millis = GMT-millis + rawOffset + dstOffset. All computations are performed in the proleptic Gregorian calendar. The default implementation in the TimeZone class delegates to the 8-argument getOffset().
Reimplemented from TimeZone. |
|
Gets the time zone offset, for current date, modified in case of daylight savings. This is the offset to add *to* UTC to get local time. Note: Don't call this method. Instead, call the getOffset(UDate...) overload, which returns both the raw and the DST offset for a given time. This method is retained only for backward compatibility.
Implements TimeZone. |
|
Returns the TimeZone's adjusted GMT offset (i.e., the number of milliseconds to add to GMT to get local time in this time zone, taking daylight savings time into account) as of a particular reference date. The reference date is used to determine whether daylight savings time is in effect and needs to be figured into the offset that is returned (in other words, what is the adjusted GMT offset in this time zone at this particular date and time?). For the time zones produced by createTimeZone(), the reference data is specified according to the Gregorian calendar, and the date and time fields are local standard time. Note: Don't call this method. Instead, call the getOffset(UDate...) overload, which returns both the raw and the DST offset for a given time. This method is retained only for backward compatibility.

|
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()) ...

Implements BasicTimeZone. |
|
Returns true if this zone has the same rule and offset as another zone. That is, if this zone differs only in ID, if at all.
Reimplemented from TimeZone. |
|
Queries if the given date is in daylight savings time in this time zone. This method is wasteful since it creates a new GregorianCalendar and deletes it each time it is called. This is a deprecated method and provided only for Java compatibility.
