Interface CompositeSet.SetMutator

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.
