```
public interface SelectionAware
```
Interface marking if a GraphProvider is "selection aware". This allows GraphProviders to filter the browser tables (e.g. alarm, node, etc) based on the current selection. In order to achieve that all selected Vertices must be converted to a list of Restrictions. The list of Restriction is represented by SelectionChangedListener.Selection.

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`boolean`	`contributesTo(ContentType type)`	Allows the `GraphProvider` to define if it contributes to a certain `ContentType`.

- Method Detail
  - getSelection
```
SelectionChangedListener.Selection getSelection(List<VertexRef> selectedVertices,
                                                ContentType type)
```
    Converts the provided selectedVertices to a Selection. The provided type represents the according browser table. This method is only invoked if contributesTo(ContentType) returns to for the provided type
    
    Parameters:
    
    selectedVertices - The vertices currently selected in the Topology UI.
    
    type - The type to filter for. Represents the according browser table.
    
    Returns:
    
    The selection containing the List of Restrictions. Must NOT be null.

  - contributesTo
```
boolean contributesTo(ContentType type)
```
    Allows the GraphProvider to define if it contributes to a certain ContentType. If false it is not shown in the browsers tab at all
    
    Parameters:
    
    type - The type to check if this contribute to
    
    Returns:
    
    true if this contributes to the provided type
