Constructor Detail

Scalar

public Scalar(U unit)

Construct a new Scalar.

Parameters:

unit - U; the unit of the new Scalar

Method Detail

getUnit

public final U getUnit()

Retrieve the unit of this Value.

Specified by:

getUnit in interface Value<U extends Unit<U>>

Returns:

U; the unit of this Value

expressAsSIUnit

public final double expressAsSIUnit(double value)

Convert a value to the standard SI unit.

Specified by:

expressAsSIUnit in interface Value<U extends Unit<U>>

Parameters:

value - double; the value to convert to the standard SI unit

Returns:

double; the value in the standard SI unit

expressAsSpecifiedUnit

protected final double expressAsSpecifiedUnit(double value)

Convert a value from the standard SI unit into the unit of this Scalar.

Parameters:

value - double; the value to convert

Returns:

double; the value in the unit of this Scalar

setDisplayUnit

public void setDisplayUnit(U newUnit)

Set a new display unit for the value. Internally, the value will stay stored in the default or SI unit.
