Class AlternateUnit<Q extends Quantity>

  • All Implemented Interfaces:

    public final class AlternateUnit<Q extends Quantity>extends DerivedUnit<Q>

    This class represents the units used in expressions to distinguish between quantities of a different nature but of the same dimensions.

    Instances of this class are created through the Unit.alternate(String) method.

      • getSymbol

        public final String getSymbol()
        Returns the symbol for this alternate unit.
        this alternate unit symbol.
      • getParent

        public final Unit<? super Q> getParent()
        Returns the parent unit from which this alternate unit is derived (a system unit itself).
        the parent of the alternate unit.
      • getStandardUnit

        public final Unit<? super Q> getStandardUnit()
        Description copied from class: Unit
        Returns the 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. \xc2\xb0C/m and K/m).

        Specified by:
        getStandardUnit in class Unit<Q extends Quantity>
        the system unit this unit is derived from.
      • toStandardUnit

        public final UnitConverter toStandardUnit()
        Description copied from class: Unit
        Returns the converter from this unit to its system unit.
        Specified by:
        toStandardUnit in class Unit<Q extends Quantity>
      • equals

        public boolean equals(Object that)
        Indicates if this alternate unit is considered equals to the specified object (both are alternate units with equal symbol, equal base units and equal converter to base units).
        Specified by:
        equals in class Unit<Q extends Quantity>
        that - the object to compare for equality.
        true if this and that are considered equals; falseotherwise.
      • hashCode

        public int hashCode()
        Description copied from class: Unit
        Returns the hash code for this unit.
        Specified by:
        hashCode in class Unit<Q extends Quantity>
        this unit hashcode value.
