public abstract class AbstractObjectSet<K>
extends AbstractObjectCollection<K>
implements java.lang.Cloneable, ObjectSet<K>
An abstract class providing basic methods for sets implementing a type-specific interface.

Note that the type-specific Set interface adds a type-specific remove() method, as it is no longer harmful for subclasses. Thus, concrete subclasses of this class must implement remove() (the rem() implementation of this class just delegates to remove()).
