Throws:

IllegalArgumentException - if given quantities is null or empty or contains any null values or contains quantities of mixed scale

fromArray

@SafeVarargs
public static <Q extends javax.measure.Quantity<Q>> MixedQuantity<Q> fromArray(javax.measure.Quantity<Q>... quantities)

Type Parameters:

Q -

Parameters:

quantities -

Returns:

a MixedQuantity with the specified quantities

Throws:

IllegalArgumentException - if given quantities is null or empty or contains any null values or contains quantities of mixed scale

of

public static <Q extends javax.measure.Quantity<Q>> MixedQuantity<Q> of(List<javax.measure.Quantity<Q>> quantities)

Type Parameters:

Q -

Parameters:

quantities -

Returns:

a MixedQuantity with the specified quantities

Throws:

IllegalArgumentException - if given quantities is null or empty or contains any null values or contains quantities of mixed scale

getUnits

public List<javax.measure.Unit<Q>> getUnits()

Gets the list of units in this MixedQuantity.

This list can be used in conjunction with getQuantities() to access the entire quantity.

Returns:

a list containing the units, not null

getQuantities

public List<javax.measure.Quantity<Q>> getQuantities()

Gets quantities in this MixedQuantity.

Returns:

a list containing the quantities, not null

toString

public String toString()

Overrides:

toString in class Object

to

public javax.measure.Quantity<Q> to(javax.measure.Unit<Q> unit)

Returns the sum of all quantity values in this MixedQuantity converted into another (compatible) unit.

Specified by:

to in interface tech.uom.lib.common.function.QuantityConverter<Q extends javax.measure.Quantity<Q>>

Parameters:

unit - the Unit unit in which the returned quantity is stated.

Returns:

the sum of all quantities in this MixedQuantity or a new quantity stated in the specified unit.

Throws:

ArithmeticException - if the result is inexact and the quotient has a non-terminating decimal expansion.

equals

public boolean equals(Object obj)

Indicates if this mixed quantity is considered equal to the specified object (both are mixed units with same composing units in the same order).

Overrides:

equals in class Object

Parameters:

obj - the object to compare for equality.

Returns:

true if this and obj are considered equal; falseotherwise.

hashCode

public int hashCode()

Overrides:

hashCode in class Object
