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 & getFallbackIntervalPattern(UnicodeString &result) const
Get the fallback interval pattern.
virtual DateIntervalInfo * clone() const
Clone this object polymorphically.
DateIntervalInfo & operator=(const DateIntervalInfo &)
Assignment operator.
UBool getDefaultOrder() const
Get default order – whether the first date in pattern is later date or not.
virtual ~DateIntervalInfo()
Destructor.
void setFallbackIntervalPattern(const UnicodeString &fallbackPattern, UErrorCode &status)
Re-set the fallback interval pattern.
DateIntervalInfo(const DateIntervalInfo &)
Copy constructor.
UnicodeString & getIntervalPattern(const UnicodeString &skeleton, UCalendarDateFields field, UnicodeString &result, UErrorCode &status) const
Get the interval pattern given skeleton and the largest different calendar field.
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

virtual bool operator==(const DateIntervalInfo &other) const
Return true if another object is semantically equal to this one.
DateIntervalInfo(UErrorCode &status)
Default constructor.
