| * <p> | |
| * The difference between dimensional models lies in the assumptions each makes and, in consequence,the operations each permits. For example, the | |
| * summation of a {@link javax.measure.quantity.Length length} and a {@link org.unitsofmeasurement.quantity.Duration duration} is not allowed | |
| * by the standard model, but is quite valid in a relativistic context. | |
| * </p> | |
| * | |
| * <p> | |
| * Models are {@link javolution.context.LocalContext context-local}, allowing multiple models to be used concurrently. For example:[code] | |
| * LocalContext.enter(); try { RelativisticModel.select(); // Affects the current thread only. ... } finally { LocalContext.exit(); }[/code] | |
| * </p> | |
