java.util.Set<H> handles()
```

```
    Retrieves a list of all known objects for which there is a handle.
    
    Type Parameters:
    
    T - As of convenience, the type of the reference returned. CAUTION: The type T being a sub-type of REF has the drawback that in case you specify a sub-type of REF (T), you may end up with a class cast exception in case you do not make sure that the handle references the expected type T.

    The list of the objects managed by a handle.
