7. Implementing IManageState
Implementation of the IManageState interface is not required in order to claim OpenMI compliance. However, if you want to use your model in configurations where iterations are needed or you want to use calibration or optimization controllers, the implementation of the IManageState interface is required. Normally, you should put the bulk of the implementation into the engine core and save the data required in order to restore a state in memory.
7.1 The IManageState interface
Implementation of the IManageState interface is shown in Figure 20.

- In MyLinkableEngine, specify that it implements the IManageState interface.
- In MyEngineWrapper, specify that it implements the IManageState interface.
- Implement the IManageState methods in all wrapper classes. The implementation will typically be very simple code that redirects the call to the next wrapper class and finally to the engine core, where the bulk of the implementation is located.

8. The OMI file
The OMI file defines the entry point to a LinkableComponent. It contains information on the software unit to instantiate and the arguments to provide at initialization. This file makes it possible for a user interface to deploy your model.
