#define U_NAMESPACE_END
This is used to end a declaration of a public ICU C++ API.
Selector for short display name derived from the time zone's fallback name.
USystemTimeZoneType
System time zone type constants used by filtering zones in ucal_openTimeZoneIDEnumeration.
UErrorCode
Error code to replace exception handling, so that the code is compatible with all C++ compilers...
Basic definitions for ICU, for both C and C++ APIs.
UnicodeString is a string class that stores Unicode characters directly and provides similar function...
struct UResourceBundle UResourceBundle
UObject is the common ICU "boilerplate" class.
