it.unimi.dsi.fastutil.doubles.DoubleSets.Singleton

All Implemented Interfaces:: DoubleCollection, DoubleIterable, DoubleSet, Serializable, Cloneable, Iterable<Double>, Collection<Double>, Set<Double>

Direct Known Subclasses:: DoubleSortedSets.Singleton

Enclosing class:: DoubleSets

public static class DoubleSets.Singleton
extends AbstractDoubleSet
implements Serializable, Cloneable

An immutable class representing a type-specific singleton set.

This class may be useful to implement your own in case you subclass a type-specific set.

Method Details
- contains
  
  public boolean contains(double k)
  
  Description copied from class: AbstractDoubleCollection
  
  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 DoubleCollection
  
  Overrides:
  
  contains in class AbstractDoubleCollection
  
  See Also:
  
  Collection.contains(Object)
- remove
  
  public boolean remove(double k)
  
  Description copied from class: AbstractDoubleSet
  
  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 DoubleSet
  
  Overrides:
  
  remove in class AbstractDoubleSet
  
  See Also:
  
  Collection.remove(Object)
- iterator
  
  public DoubleListIterator iterator()
  
  Description copied from interface: DoubleCollection
  
  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<Double>
  
  Specified by:
  
  iterator in interface DoubleCollection
  
  Specified by:
  
  iterator in interface DoubleIterable
  
  Specified by:
  
  iterator in interface DoubleSet
  
  Specified by:
  
  iterator in interface Iterable<Double>
  
  Specified by:
  
  iterator in interface Set<Double>
  
  Specified by:
  
  iterator in class AbstractDoubleSet
  
  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<Double>
  
  Specified by:
  
  size in interface Set<Double>
  
  Specified by:
  
  size in class AbstractCollection<Double>
- addAll
  
  public boolean addAll(Collection<? extends Double> c)
  
  Specified by:
  
  addAll in interface Collection<Double>
  
  Specified by:
  
  addAll in interface Set<Double>
  
  Overrides:
  
  addAll in class AbstractCollection<Double>
- removeAll
  
  public boolean removeAll(Collection<?> c)
  
  Specified by:
  
  removeAll in interface Collection<Double>
  
  Specified by:
  
  removeAll in interface Set<Double>
  
  Overrides:
  
  removeAll in class AbstractCollection<Double>
- retainAll
  
  public boolean retainAll(Collection<?> c)
  
  Specified by:
  
  retainAll in interface Collection<Double>
  
  Specified by:
  
  retainAll in interface Set<Double>
  
  Overrides:
  
  retainAll in class AbstractCollection<Double>
- addAll
  
  public boolean addAll(DoubleCollection c)
  
  Description copied from interface: DoubleCollection
  
  Adds all elements of the given type-specific collection to this collection.
  
  Specified by:
  
  addAll in interface DoubleCollection
  
  Overrides:
  
  addAll in class AbstractDoubleCollection
  
  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(DoubleCollection c)
  
  Description copied from interface: DoubleCollection
  
  Remove from this collection all elements in the given type-specific collection.
  
  Specified by:
  
  removeAll in interface DoubleCollection
  
  Overrides:
  
  removeAll in class AbstractDoubleCollection
  
  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(DoubleCollection c)
  
  Description copied from interface: DoubleCollection
  
  Retains in this collection only elements from the given type-specific collection.
  
  Specified by:
  
  retainAll in interface DoubleCollection
  
  Overrides:
  
  retainAll in class AbstractDoubleCollection
  
  Parameters:
  
  c - a type-specific collection.
  
  Returns:
  
  true if this collection changed as a result of the call.
