      • add

        public boolean add​(long k)
        Description copied from interface: LongCollection
        Ensures that this collection contains the specified element (optional operation).
        Specified by:
        add in interface LongCollection

        Collection.add(Object)

      • contains

        public boolean contains​(long k)
        Description copied from interface: LongCollection
        Returns true if this collection contains the specified element.
        Specified by:
        contains in interface LongCollection
        See Also:

      • rem

        public boolean rem​(long k)
        Description copied from interface: LongCollection
        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().

        rem in interface LongCollection
