Constructor Detail

Acceleration

public Acceleration(double value,
                    int unit)

Acceleration constructor.

Parameters:

value - the acceleration in the specified unit.

unit - the measurement unit being used.

Throws:

ArrayIndexOutOfBoundsException - unknown measurement unit

Acceleration

public Acceleration(Composite c)

Acceleration constructor from Composite quantity.

Parameters:

c - the quantity to convert.

Throws:

UnitDimensionException - composite is not an acceleration.

See Also:

Composite

Method Detail

getValue

public double getValue(int unit)

Gets the acceleration in the specified unit.

Parameters:

unit - the measurement unit being used.

Returns:

acceleration in the specified measurement unit.

Throws:

ArrayIndexOutOfBoundsException - unknown measurement unit

setValue

public void setValue(double value,
                     int unit)

Sets this Acceleration using the specified unit.

Parameters:

value - the new acceleration in the specified unit.

unit - the measurement unit being used.

Throws:

ArrayIndexOutOfBoundsException - unknown measurement unit

add

public Acceleration add(Acceleration x)

Returns an Acceleration whose value is (this + x).

Parameters:

x - the Acceleration to be added.

Returns:

(this + x)

substract

public Acceleration substract(Acceleration x)

Returns an Acceleration whose value is (this - x).

Parameters:

x - the Acceleration to be substracted.

Returns:

(this - x)

multiply

public Acceleration multiply(double coefficient)

Returns an Acceleration whose value is (this * coefficient).

Parameters:

coefficient - the dimensionless multiplier.

Returns:

(this * coefficient)

divide

public Acceleration divide(double coefficient)

Returns an Acceleration whose value is (this / coefficient).

Parameters:

coefficient - the dimensionless divisor.

Returns:

(this / coefficient)

Throws:

ArithmeticException - coefficient == 0.0

multiply

public Speed multiply(Duration d)

Returns a Speed whose value is (this * d).

Parameters:

d - the duration multiplier.

Returns:

(this * d)

compareTo

public int compareTo(Acceleration x)

Compares this Acceleration with the specified Acceleration. 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 - Acceleration to which this Acceleration is to be compared.

Returns:

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

compareTo

public int compareTo(Object o)

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

Specified by:

compareTo in interface Comparable

Parameters:

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

Returns:

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

Throws:

ClassCastException - o is not a Acceleration.

compareTo(Acceleration), Comparable

getValueSI

protected double getValueSI()

Gets the acceleration in SI units.

Specified by:

getValueSI in class AbstractQuantity

Returns:

acceleration in SI units.

getDimensionSI

protected int getDimensionSI()

Gets the SI dimension of this Acceleration.

Specified by:

getDimensionSI in class AbstractQuantity

Returns:

LENGTH - 2 * TIME
