Type Parameters
- T
 The type of items stored in the set.
The IReadOnlyObservableSet<T> type exposes the following members.

Methods
| Name | Description | |
|---|---|---|
| .gif) | Contains(Object) | Determines whether the IReadOnlyObservableSet contains a specific value. (Inherited from IReadOnlyObservableSet.) | 
| .gif) | Contains(T) | Determines whether the IReadOnlyObservableSet<T> contains a specific value. | 
| .gif) | GetEnumerator | Returns an enumerator that iterates through the collection. (Inherited from IEnumerable<T>.) |

Remarks
This interface is used by the ReadOnlyObservableSet<T> base class to specifically filter hierarchy items (not progressive nodes) in a solution filter. If you are creating a solution filter from scratch, use IReadOnlyObservableSet.
