public class LinearDensity
extends TypedDoubleScalarRel<LinearDensityUnit,LinearDensity>

Easy access methods for the LinearDensity DoubleScalar, which is relative by definition. Instead of:

 DoubleScalar.Rel<LinearDensityUnit> value = new DoubleScalar.Rel<LinearDensityUnit>(100.0, LinearDensityUnit.SI);
 

we can now write:

 LinearDensity value = new LinearDensity(100.0, LinearDensityUnit.SI);
 

The compiler will automatically recognize which units belong to which quantity, and whether the quantity type and the unit used are compatible.
