Detailed Description

An amount of a specified unit, consisting of a number and a Unit.

For example, a length measure consists of a number and a length unit, such as feet or meters.

Measure objects are formatted by MeasureFormat.

Measure objects are immutable.

Constructor & Destructor Documentation

icu::Measure::Measure	(	const Formattable &	number,
		MeasureUnit *	adoptedUnit,
		UErrorCode &	ec
	)

Construct an object with the given numeric amount and the given unit.

After this call, the caller must not delete the given unit object.

Parameters:

	number	a numeric object; amount.isNumeric() must be TRUE
	adoptedUnit	the unit object, which must not be NULL
	ec	input-output error code. If the amount or the unit is invalid, then this will be set to a failing value.

virtual UObject* icu::Measure::clone ( ) const [virtual]

Return a polymorphic clone of this object.

The result will have the same class as returned by getDynamicClassID().

Stable:: ICU 3.0

Reimplemented in icu::CurrencyAmount, and icu::TimeUnitAmount.

virtual UClassID icu::Measure::getDynamicClassID ( void ) const [virtual]

Returns a unique class ID POLYMORPHICALLY.

Pure virtual override. This method is to implement a simple version of RTTI, since not all C++ compilers support genuine RTTI. Polymorphic operator==() and clone() methods call this method.

Returns:: The class ID for this object. All objects of a given class have the same class ID. Objects of other classes have different class IDs.

Stable:: ICU 53

Reimplemented from icu::UObject.

Reimplemented in icu::CurrencyAmount, and icu::TimeUnitAmount.

const Formattable & icu::Measure::getNumber ( ) const [inline]

Return a reference to the numeric value of this object.

The numeric value may be of any numeric type supported by Formattable.

static UClassID icu::Measure::getStaticClassID ( void ) [static]

Return the class ID for this class.

This is useful only for comparing to a return value from getDynamicClassID(). For example:

 .   Base* polymorphic_pointer = createPolymorphicObject();
 .   if (polymorphic_pointer->getDynamicClassID() ==
 .       erived::getStaticClassID()) ...
