Definition fmtable.h:63
icu::MeasureUnit
A unit such as length, mass, volume, currency, etc.
Definition measunit.h:405
icu::Measure::clone
virtual Measure * clone() const
Return a polymorphic clone of this object.
icu::Measure::getStaticClassID
static UClassID getStaticClassID()
Return the class ID for this class.
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:98
icu::Measure::~Measure
virtual ~Measure()
Destructor.
icu::Measure::Measure
Measure()
Default constructor.
icu::Measure::getUnit
const MeasureUnit & getUnit() const

icu::UObject
UObject is the common ICU "boilerplate" class.
Definition uobject.h:222
fmtable.h
C++ API: Formattable is a thin wrapper for primitive types used for formatting and parsing.
