DateIntervalFormat is a class for formatting and parsing date intervals in a language-independent man...
Definition: dtitvfmt.h:300
DateIntervalInfo is a public class for encapsulating localizable date time interval patterns.
Definition: dtitvinf.h:154
void setIntervalPattern(const UnicodeString &skeleton, UCalendarDateFields lrgDiffCalUnit, const UnicodeString &intervalPattern, UErrorCode &status)
Provides a way for client to build interval patterns.
UnicodeString & getIntervalPattern(const UnicodeString &skeleton, UCalendarDateFields field, UnicodeString &result, UErrorCode &status) const
Get the interval pattern given skeleton and the largest different calendar field.
UBool getDefaultOrder() const
Get default order – whether the first date in pattern is later date or not.
virtual ~DateIntervalInfo()
Destructor.
virtual DateIntervalInfo * clone() const
Clone this object polymorphically.
DateIntervalInfo & operator=(const DateIntervalInfo &)
Assignment operator.
void setFallbackIntervalPattern(const UnicodeString &fallbackPattern, UErrorCode &status)
Re-set the fallback interval pattern.
DateIntervalInfo(const DateIntervalInfo &)
Copy constructor.
DateIntervalInfo(const Locale &locale, UErrorCode &status)
Construct DateIntervalInfo for the given locale,.
static UClassID getStaticClassID()
ICU "poor man's RTTI", returns a UClassID for this class.
virtual UClassID getDynamicClassID() const override
ICU "poor man's RTTI", returns a UClassID for the actual class.
virtual bool operator==(const DateIntervalInfo &other) const
Return true if another object is semantically equal to this one.
DateIntervalInfo(UErrorCode &status)
Default constructor.
UnicodeString & getFallbackIntervalPattern(UnicodeString &result) const
Get the fallback interval pattern.
A Locale object represents a specific geographical, political, or cultural region.
Definition: locid.h:195
UObject is the common ICU "boilerplate" class.
Definition: uobject.h:223
UnicodeString is a string class that stores Unicode characters directly and provides similar function...

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.
UErrorCode
Standard ICU4C error code type, a substitute for exceptions.
Definition: utypes.h:415
#define U_I18N_API
Set to export library symbols from inside the i18n library, and to import them from outside.
