public static interface Dimension.Model
base units
and dimensions. Custom models may allow
conversions not possible using the standard model.
For example:[code]
public static void main(String[] args) {
Dimension.Model relativistic = new Dimension.Model() {
RationalConverter meterToSecond = new RationalConverter(1, 299792458); // 1/c
public Dimension getDimension(BaseUnit unit) {
if (unit.equals(SI.METER)) return Dimension.TIME;
return Dimension.Model.STANDARD.getDimension(unit);
}
public UnitConverter getTransform(BaseUnit unit) {
if (unit.equals(SI.METER)) return meterToSecond;
return Dimension.Model.STANDARD.getTransform(unit);
}};
Dimension.setModel(relativistic);
// Converts 1.0 GeV (energy) to kg (mass).
System.out.println(Unit.valueOf("GeV").getConverterTo(KILOGRAM).convert(1.0));
}
