All Implemented Interfaces:: ShortCollection, ShortIterable, ShortSet, Serializable, Cloneable, Iterable<Short>, Collection<Short>, Set<Short>

Direct Known Subclasses:: ShortSortedSets.EmptySet

Enclosing class:: ShortSets

public static class ShortSets.EmptySet
extends ShortCollections.EmptyCollection
implements ShortSet, Serializable, Cloneable

An immutable class representing the empty set and implementing a type-specific set interface.

Method Details
- remove
  
  public boolean remove(short ok)
  
  Description copied from interface: ShortSet
  
  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.
  
  Specified by:
  
  remove in interface ShortSet

  Specified by:
  
  equals in interface Set<Short>
  
  Overrides:
  
  equals in class ShortCollections.EmptyCollection
- rem
  
  @Deprecated public boolean rem(short k)
  
  Deprecated.
  
  Description copied from class: AbstractShortCollection
  
  Removes a single instance of the specified element from this collection, if it is present (optional operation).
  Note that this method should be called remove(), but the clash with the similarly named index-based method in the List interface forces us to use a distinguished name. For simplicity, the set interfaces reinstates remove().
  This implementation iterates over the elements in the collection, looking for the specified element and tries to remove it.
