Description
| Class Summary | |
| HighEnergyModel | This class represents the high-energy model. |
| NaturalModel | This class represents the natural model. |
| PhysicalModel | This abstract class represents a physical model. |
| QuantumModel | This class represents the quantum model. |
| RelativisticModel | This class represents the relativistic model. |
| StandardModel | This class represents the standard model. |
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:
| Model | Class | Defining Characteristics | Default Output Units |
