EnvironmentOptions

java.lang.Object
- com.nomagic.magicdraw.core.options.EnvironmentOptions

```
@OpenApi
public class EnvironmentOptions
extends java.lang.Object
```
Represents application environment options.

Application-related options are referred to as environment options. They are saved in the global.opt file that is located in <USER_HOME_DIR>/.magicdraw/<VERSION_NUMBER>/data.

You can add custom environment options for MagicDraw.

To add your own environment options
- 1. Extend the AbstractPropertyOptionsGroup class.
- 2. Add the extending class to application environment options.
Example: Adding custom environment options
```
 class MyOptionsGroup extends AbstractPropertyOptionsGroup
 {
     ...
 }

 Application application = Application.getInstance();
 EnvironmentOptions options = application.getEnvironmentOptions();
 options.addGroup(new ExampleOptionsGroup());
 
```
