public abstract class AbstractObjectSet<K>
extends AbstractObjectCollection<K>
implements 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()).

Method Summary

int	hashCode()	Returns a hash code for this set.
abstract ObjectIterator<K>	iterator()	Returns a type-specific iterator on the elements of this collection.

Method Details

iterator

public abstract ObjectIterator<K> iterator()

Description copied from interface: ObjectCollection

Returns a type-specific iterator on the elements of this collection.

Note that this specification strengthens the one given in Iterable.iterator(), which was already strengthened in the corresponding type-specific class, but was weakened by the fact that this interface extends Collection.

Specified by:

iterator in interface Collection<K>

Specified by:

iterator in interface Iterable<K>

Specified by:

iterator in interface ObjectCollection<K>

Specified by:

iterator in interface ObjectIterable<K>

Specified by:

iterator in interface ObjectSet<K>

Specified by:

iterator in interface Set<K>

Specified by:

iterator in class AbstractObjectCollection<K>

Returns:

a type-specific iterator on the elements of this collection.

Iterable.iterator()

equals

public boolean equals(Object o)

Specified by:

equals in interface Collection<K>

Specified by:

equals in interface Set<K>

Overrides:

equals in class Object

hashCode

public int hashCode()

Returns a hash code for this set. The hash code of a set is computed by summing the hash codes of its elements.

Specified by:

hashCode in interface Collection<K>

Specified by:

hashCode in interface Set<K>

Overrides:

hashCode in class Object

Returns:

a hash code for this set.
