Package com.dautelle.physics.models Description

Provides models for physical quantities.

The difference between models lies in the assumptions each makes and, in consequence,the operations each permits. For example, the summation of a Length and a Duration is not allowed by the standard model, but is quite valid in a relativistic context.

Also, the current model specifies the default output units for physical quantities (Ref. Quantity.getOutputUnit()).

Note: These models are similar to the physical models from the SIunit C++ library, except that the current model is selected at run-time. In addition, models are context-local, different models can be used concurrently in LocalContext.

The names and characteristics of the models are presented in the following table:
