virtual UClassID getDynamicClassID() const
ICU4C "poor man's RTTI", returns a UClassID for the actual ICU class.
UCollationResult
UCOL_LESS is returned if source string is compared to be less than target string in the ucol_strcoll(...
U_EXPORT UBool operator==(const StringPiece &x, const StringPiece &y)
Global operator == for StringPiece.
void * UClassID
UClassID is used to identify classes without using the compiler's RTTI.
#define U_I18N_API
Set to export library symbols from inside the i18n library, and to import them from outside...
The RuleBasedCollator class provides the implementation of Collator, using data-driven tables...
C++ API: Collation Service.
UBool operator!=(const StringPiece &x, const StringPiece &y)
Global operator != for StringPiece.
EComparisonResult
LESS is returned if source string is compared to be less than target string in the compare() method...
Collation keys are generated by the Collator class.
C++ API: Common ICU base class UObject.
UErrorCode
Standard ICU4C error code type, a substitute for exceptions.
Basic definitions for ICU, for both C and C++ APIs.
UObject is the common ICU "boilerplate" class.
int8_t UBool
The ICU boolean type, a signed-byte integer.
