CompositeSet.SetMutator (Commons Collections 3.2.2 API)

All Superinterfaces:

CompositeCollection.CollectionMutator

Enclosing class:

CompositeSet
```
public static interface CompositeSet.SetMutator
extends CompositeCollection.CollectionMutator
```
Define callbacks for mutation operations.
Defining remove() on implementations of SetMutator is pointless as they are never called by CompositeSet.
