public static class IntSets.EmptySet extends IntCollections.EmptyCollection implements IntSet, java.io.Serializable, java.lang.Cloneable
An immutable class representing the empty set and implementing a type-specific set interface.This class may be useful to implement your own in case you subclass a type-specific set.

Method Detail

remove
public boolean remove(int ok)
Description copied from interface:IntSet
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 theList
interface.

rem
@Deprecated public boolean rem(int k)
Deprecated.Description copied from class:AbstractIntCollection
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 theList
interface forces us to use a distinguished name. For simplicity, the set interfaces reinstatesremove()
.This implementation iterates over the elements in the collection, looking for the specified element and tries to remove it.
