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

Measure() [1/3]

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.

Member Function Documentation

clone()

virtual UObject* 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 TimeUnitAmount, and CurrencyAmount.

getDynamicClassID()

virtual UClassID 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 UObject.

Reimplemented in TimeUnitAmount, and CurrencyAmount.

getNumber()

const Formattable & 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.

Stable:

ICU 3.0

Definition at line 148 of file measure.h.

getStaticClassID()

static UClassID 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()) ...

Returns

The class ID for all objects of this class.

Stable:

ICU 53

getUnit()

const MeasureUnit & Measure::getUnit ( ) const

inline

Return a reference to the unit of this object.

Stable:

ICU 3.0

Definition at line 152 of file measure.h.

Referenced by CurrencyAmount::getCurrency().

operator=()

Measure& Measure::operator=

(

const Measure &

other

)

Assignment operator.

Stable:

ICU 3.0

operator==()

UBool Measure::operator==

(

const UObject &

other

)

const

Equality operator.

Return true if this object is equal to the given object.
