Method Details

getValue

public Short getValue()

Description copied from class: AbstractQuantity

Returns the numeric value of the quantity.

Specified by:

getValue in interface javax.measure.Quantity<Q extends javax.measure.Quantity<Q>>

Specified by:

getValue in interface tech.uom.lib.common.function.ValueSupplier<Q extends javax.measure.Quantity<Q>>

Specified by:

getValue in class AbstractQuantity<Q extends javax.measure.Quantity<Q>>

Returns:

the quantity value.

doubleValue

public double doubleValue(javax.measure.Unit<Q> unit)

Specified by:

doubleValue in class AbstractQuantity<Q extends javax.measure.Quantity<Q>>

longValue

public long longValue(javax.measure.Unit<Q> unit)

Overrides:

longValue in class AbstractQuantity<Q extends javax.measure.Quantity<Q>>

isBig

public boolean isBig()

Specified by:

isBig in class AbstractQuantity<Q extends javax.measure.Quantity<Q>>

inverse

public ComparableQuantity<?> inverse()

See Also:

equals

public boolean equals(Object obj)

Description copied from class: AbstractQuantity

Compares this quantity against the specified object for strict equality (same unit and same amount).

Similarly to the BigDecimal.equals(Object) method which consider 2.0 and 2.00 as different objects because of different internal scales, quantities such as Quantities.getQuantity(3.0, KILOGRAM) Quantities.getQuantity(3, KILOGRAM) and Quantities.getQuantity("3 kg") might not be considered equals because of possible differences in their implementations.

To compare quantities stated using different units or using different amount implementations the compareTo or

invalid reference

equals(Quantity, epsilon, epsilonUnit)

methods should be used.

Overrides:

equals in class AbstractQuantity<Q extends javax.measure.Quantity<Q>>

Parameters:

obj - the object to compare with.

Returns:

this.getUnit.equals(obj.getUnit()) invalid input: '&'invalid input: '&' this.getValue().equals(obj.getValue())
