You can move attributes, methods and events of an interface to a component interface if you have interface nesting . For more information, see Class Diagram .
If the interface is already implemented by classes, you need to make certain adjustments to the classes. The Refactoring Assistant performs these adjustments for you.
The selected components of the interface are created in the component interface and the required adjustments are made to the implementing class.
You can also split an implemented interface using the described function. For more information, see Splitting Interfaces .
