Interface CompositeSet.SetMutator<E>

All Superinterfaces:

CompositeCollection.CollectionMutator<E>

Enclosing class:

CompositeSet<E>

public static interface CompositeSet.SetMutator<E>
extends CompositeCollection.CollectionMutator<E>

Define callbacks for mutation operations.

Defining remove() on implementations of SetMutator is pointless as they are never called by CompositeSet.
