javax.measure.unit
public final class CompoundUnit<Q extends Quantity> extends DerivedUnit<Q>
Unit.compound
method.
Examples of compound units:
Unit<Duration> HOUR_MINUTE_SECOND = HOUR.compound(MINUTE).compound(SECOND); Unit<Angle> DEGREE_MINUTE_ANGLE = DEGREE_ANGLE.compound(MINUTE_ANGLE);
Modifier and Type | Method and Description |
---|---|
boolean |
equals(java.lang.Object that)
Indicates if this compound unit is considered equals to the specified object (both are compound units with same
composing units in the same order).
|
Unit<Q> |
getHigher()
Returns the higher unit of this compound unit.
|
Unit<Q> |
getLower()
Returns the lower unit of this compound unit.
|
Unit<? super Q> |
getStandardUnit()
Returns the
base unit , alternate unit or product of base units and
alternate units this unit is derived from. |
int |
hashCode()
Returns the hash code for this unit.
|
UnitConverter |
toStandardUnit()
Returns the converter from this unit to its system unit.

Unit
base unit
, alternate unit
or product of base units and
alternate units this unit is derived from. The standard unit identifies the "type" of
quantity
for which this unit is employed. For example:
boolean isAngularVelocity(Unit<?> u) { return u.getStandardUnit().equals(RADIAN.divide(SECOND)); } assert(REVOLUTION.divide(MINUTE).isAngularVelocity());
Note: Having the same system unit is not sufficient to ensure that a converter exists between the two units (e.g. °C/m and K/m).
