icu::Formattable
Formattable objects can be passed to the Format class or its subclasses for formatting.
Definition: fmtable.h:64
icu::MeasureUnit
A unit such as length, mass, volume, currency, etc.
Definition: measunit.h:369
icu::Measure
An amount of a specified unit, consisting of a number and a Unit.
Definition: measure.h:45
icu::Measure::Measure
Measure(const Formattable &number, MeasureUnit *adoptedUnit, UErrorCode &ec)
Construct an object with the given numeric amount and the given unit.
icu::Measure::operator!=
bool operator!=(const UObject &other) const
Inequality operator.
Definition: measure.h:99
icu::Measure::~Measure
virtual ~Measure()
Destructor.
icu::Measure::Measure
Measure()
Default constructor.
icu::Measure::clone
virtual Measure * clone() const
Return a polymorphic clone of this object.
icu::Measure::operator=
Measure & operator=(const Measure &other)
Assignment operator.
icu::Measure::getStaticClassID
static UClassID getStaticClassID(void)
Return the class ID for this class.
icu::Measure::Measure
Measure(const Measure &other)
Copy constructor.
icu::Measure::getDynamicClassID
virtual UClassID getDynamicClassID(void) const override
Returns a unique class ID POLYMORPHICALLY.
icu::Measure::operator==
bool operator==(const UObject &other) const
Equality operator.
icu::UObject
UObject is the common ICU "boilerplate" class.
Definition: uobject.h:223
fmtable.h
C++ API: Formattable is a thin wrapper for primitive types used for formatting and parsing.
icu::operator==
U_EXPORT UBool operator==(const StringPiece &x, const StringPiece &y)
Global operator == for StringPiece.
UClassID
void * UClassID
UClassID is used to identify classes without using the compiler's RTTI.
Definition: uobject.h:96
utypes.h
Basic definitions for ICU, for both C and C++ APIs.
UErrorCode
UErrorCode
Standard ICU4C error code type, a substitute for exceptions.
Definition: utypes.h:415
U_I18N_API
