it.unimi.dsi.fastutil.ints.IntSets.Singleton

All Implemented Interfaces:: IntCollection, IntIterable, IntSet, Serializable, Cloneable, Iterable<Integer>, Collection<Integer>, Set<Integer>

Direct Known Subclasses:: IntSortedSets.Singleton

Enclosing class:: IntSets

public static class IntSets.Singleton
extends AbstractIntSet
implements Serializable, Cloneable

An immutable class representing a type-specific singleton set.

Method Details
- contains
  
  public boolean contains(int k)
  
  Description copied from class: AbstractIntCollection
  
  Returns true if this collection contains the specified element.
  This implementation iterates over the elements in the collection, looking for the specified element.
  
  Specified by:
  
  contains in interface IntCollection
  
  Overrides:
  
  contains in class AbstractIntCollection
  
  See Also:
  
  Collection.contains(Object)
- remove
  
  public boolean remove(int k)
  
  Description copied from class: AbstractIntSet
  
  Removes an element from this set.
  Note that the corresponding method of a type-specific collection is rem(). This unfortunate situation is caused by the clash with the similarly named index-based method in the List interface. Delegates to the type-specific rem() method implemented by type-specific abstract Collection superclass.
  
  Specified by:
  
  remove in interface IntSet
  
  Overrides:
  
  remove in class AbstractIntSet
  
  See Also:
  
  Collection.remove(Object)
- iterator
  
  public IntListIterator iterator()
  
  Description copied from interface: IntCollection
  
  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<Integer>
  
  Specified by:
  
  iterator in interface IntCollection
  
  Specified by:
  
  iterator in interface IntIterable
  
  Specified by:
  
  iterator in interface IntSet
  
  Specified by:
  
  iterator in interface Iterable<Integer>
  
  Specified by:
  
  iterator in interface Set<Integer>
  
  Specified by:
  
  iterator in class AbstractIntSet
  
  Returns:
  
  a type-specific iterator on the elements of this collection.
  
  See Also:
  
  Iterable.iterator()
- size
  
  public int size()
  
  Specified by:
  
  size in interface Collection<Integer>
  
  Specified by:
  
  size in interface Set<Integer>
  
  Specified by:
  
  size in class AbstractCollection<Integer>
- addAll
  
  public boolean addAll(Collection<? extends Integer> c)
  
  Specified by:
  
  addAll in interface Collection<Integer>
  
  Specified by:
  
  addAll in interface Set<Integer>
  
  Overrides:
  
  addAll in class AbstractCollection<Integer>
- removeAll
  
  public boolean removeAll(Collection<?> c)
  
  Specified by:
  
  removeAll in interface Collection<Integer>
  
  Specified by:
  
  removeAll in interface Set<Integer>
  
  Overrides:
  
  removeAll in class AbstractCollection<Integer>
- retainAll
  
  public boolean retainAll(Collection<?> c)
  
  Specified by:
  
  retainAll in interface Collection<Integer>
  
  Specified by:
  
  retainAll in interface Set<Integer>
  
  Overrides:
  
  retainAll in class AbstractCollection<Integer>
- addAll
  
  public boolean addAll(IntCollection c)
  
  Description copied from interface: IntCollection
  
  Adds all elements of the given type-specific collection to this collection.
  
  Specified by:
  
  addAll in interface IntCollection
  
  Overrides:
  
  addAll in class AbstractIntCollection
  
  Parameters:
  
  c - a type-specific collection.
  
  Returns:
  
  true if this collection changed as a result of the call.
  
  See Also:
  
  Collection.addAll(Collection)
- removeAll
  
  public boolean removeAll(IntCollection c)
  
  Description copied from interface: IntCollection
  
  Remove from this collection all elements in the given type-specific collection.
  
  Specified by:
  
  removeAll in interface IntCollection
  
  Overrides:
  
  removeAll in class AbstractIntCollection
  
  Parameters:
  
  c - a type-specific collection.
  
  Returns:
  
  true if this collection changed as a result of the call.
  
  See Also:
  
  Collection.removeAll(Collection)
- retainAll
  
  public boolean retainAll(IntCollection c)
  
  Description copied from interface: IntCollection
  
  Retains in this collection only elements from the given type-specific collection.
  
  Specified by:
  
  retainAll in interface IntCollection
  
  Overrides:
  
  retainAll in class AbstractIntCollection
  
  Parameters:
  
  c - a type-specific collection.
  
  Returns:
  
  true if this collection changed as a result of the call.
