public abstract class AbstractObjectSet<K>
extends it.unimi.dsi.fastutil.objects.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()).

iterator

public abstract it.unimi.dsi.fastutil.objects.ObjectIterator<K> iterator()

Description copied from interface: ObjectSet

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

Specified by:

iterator in interface it.unimi.dsi.fastutil.objects.ObjectCollection<K>

Specified by:

iterator in interface it.unimi.dsi.fastutil.objects.ObjectIterable<K>

Specified by:

iterator in interface ObjectSet<K>

Specified by:

iterator in interface java.lang.Iterable<K>

Specified by:

iterator in interface java.util.Collection<K>

Specified by:

iterator in interface java.util.Set<K>

Overrides:

iterator in class it.unimi.dsi.fastutil.objects.AbstractObjectCollection<K>

Returns:

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

equals

public boolean equals(java.lang.Object o)

Specified by:

equals in interface java.util.Collection<K>

Specified by:

equals in interface java.util.Set<K>

Overrides:

equals in class java.lang.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.
