Examples of org.togglz.core.Feature

org.togglz.core.Feature
This interface represents a feature and is typically implemented by the feature enum.

Usually it makes sense to implement the following method which allows a very easy way to check the status of a feature.
```
 public boolean isActive() { return FeatureContext.getFeatureManager().isActive(this); } 
```
Please note that in Togglz 2.0 the isActive() method isn't defined in the interface any more. So when updating to Togglz 2.0, you will have to remove the {@link Override} annotation from your implementation of the method.
