## 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.

## Member Function Documentation

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::TimeUnitAmount, and icu::CurrencyAmount.

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::TimeUnitAmount, and icu::CurrencyAmount.

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.

Stable:
  ICU 3.0

Definition at line 150 of file measure.h.

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()) ...

Returns
  The class ID for all objects of this class.

Stable:
  ICU 53

const MeasureUnit & icu::Measure::getUnit | ( |  | ) | const
| inline

Return a reference to the unit of this object.

Stable:
  ICU 3.0

Definition at line 154 of file measure.h.

Measure& icu::Measure::operator= | ( | const Measure & | other | ) |

Assignment operator.

Stable:
  ICU 3.0

UBool icu::Measure::operator== | ( | const UObject & | other | ) | const

Equality operator.

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