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.

| icu::Measure::Measure | ( | const Formattable & | number, |
| MeasureUnit * | adoptedUnit, | ||

| ) |
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 nullptr 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()
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.
◆ getDynamicClassID()
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.
◆ getNumber()
|
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
◆ getStaticClassID()
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()
|
inline |
◆ operator!=()
Inequality operator.
Returns true if this object is not equal to the other object.
- Parameters
-
other the object to compare with
- Returns
- true if the objects are not equal
- Stable:
- ICU 74
