Method Detail

add

public Composite add(Composite x)

Returns a Composite whose value is (this + x).

Parameters:

x - the Composite to be added.

Returns:

(this + x)

Throws:

UnitDimensionException - different unit dimensions

subtract

public Composite subtract(Composite x)

Returns a Composite whose value is (this - x).

Parameters:

x - the Composite to be subtracted.

Returns:

(this - x)

Throws:

UnitDimensionException - different unit dimensions

multiply

public Composite multiply(double coefficient)

Returns a Composite whose value is (this * coefficient).

Parameters:

coefficient - the dimensionless multiplier.

Returns:

(this * coefficient)

divide

public Composite divide(double coefficient)

Returns a Composite whose value is (this / coefficient).

Parameters:

coefficient - the dimensionless divisor.

Returns:

(this / coefficient)

Throws:

ArithmeticException - coefficient == 0.0

inverse

public Composite inverse()

Returns the Composite whose value is (1 / this).

Returns:

(1 / this)

Throws:

ArithmeticException - this.getValueSI() == 0.0

compareTo

public int compareTo(Composite x)

Compares this Composite with the specified Composite. This method is provided in preference to individual methods for each of the six boolean comparison operators (<, ==, >, >=, !=, <=). The suggested idiom for performing these comparisons is: (x.compareTo(y) <op> 0), where <op> is one of the six comparison operators.

Parameters:

x - Composite to which this Composite is to be compared.

Returns:

-1, 0 or 1 as this Composite is numerically less than, equal to, or greater than x.

Throws:

UnitDimensionException - different unit dimensions

compareTo

public int compareTo(Object o)

Compares this Composite with the specified Object. If the Object is a Composite, this method behaves like compareTo(Composite). Otherwise, it throws a ClassCastException (as Composites are comparable only to other Composites).

Specified by:

compareTo in interface Comparable

Parameters:

o - Object to which this Composite is to be compared.

Returns:

a negative number, zero, or a positive number as this Composite is numerically less than, equal to, or greater than o, which must be a Composite.

Throws:

ClassCastException - o is not a Composite.

compareTo(Composite), Comparable

getValueSI

public double getValueSI()

Gets the quantity in SI units.

Returns:

quantity in SI units.
