Method Detail

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 ObjectCollection<K>

Specified by:

iterator in interface ObjectIterable<K>

Specified by:

iterator in interface ObjectSet<K>

Specified by:

iterator in interface Iterable<K>

Specified by:

iterator in interface Collection<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.

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.

remove

public boolean remove(Object k)

Description copied from interface: ObjectSet

Removes an element from this set.

Note that the corresponding method of the type-specific collection is rem(). This unfortunate situation is caused by the clash with the similarly named index-based method in the List interface.

Specified by:

remove in interface ObjectSet<K>

Specified by:

remove in interface Collection<K>

Specified by:

remove in interface Set<K>

Overrides:

remove in class AbstractCollection<K>
