    public static class LongSets.EmptySet
    extends LongCollections.EmptyCollection
    implements LongSet, java.io.Serializable, java.lang.Cloneable

      • rem

        @Deprecated
        public boolean rem​(long k)
        Deprecated.
        Description copied from class: AbstractLongCollection
        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().
