FMI20ContinuousStateDerivative

java.lang.Object
- org.ptolemy.fmi.FMI20ContinuousStateDerivative

```
public class FMI20ContinuousStateDerivative
extends java.lang.Object
```
An object that represents the Derivatives of a continuous state variable of an FMU for FMI-2.0.
A Functional Mock-up Unit file is a .fmu file in zip format that contains a .xml file named "modelDescription.xml". In that file, the Derivatives element may contain elements such as Unknown.

FMI documentation may be found at http://www.modelisar.com/fmi.html.
