All Known Implementing Classes:

Enclosing class:
Dimension
public static interface Dimension.Model
This interface represents the mapping between 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)); } > 1.7826617302520883E-27[/code]
