public static class IntSets.EmptySet
extends IntCollections.EmptyCollection
implements IntSet, Serializable, 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 the 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 IntSet
