      • copy

        public IntSet copy()
        Description copied from class: IntSet
        Create a copy of this IntSet that leaves the original unchanged.
        Specified by:
        copy in class IntSet
        Returns:
        an IntSet containing the same integers. The result will not necessarily be the same class as the original. It will either be an immutable object, or a newly constructed object.

        public IntSet mutableCopy()
        Description copied from class: IntSet
        Create a copy of this IntSet that contains the same set of integers.

        mutableCopy in class IntSet
        Returns:
        an IntSet containing the same integers. The result will not necessarily be the same class as the original. It will always be a mutable object

      • isMutable

        public boolean isMutable()

        isMutable in class IntSet
        Returns:
        true if the set permits in-situ modifications

        Specified by:
        clear in class IntSet

      • size

        public int size()
        Description copied from class: IntSet
        Get the number of integers in the set

        Description copied from class: IntSet
        Determine if the set is empty
        Specified by:
        isEmpty in class IntSet
        Returns:
        true if the set is empty, false if not

      • contains

        public boolean contains​(int value)
        Description copied from class: IntSet
        Determine whether a particular integer is present in the set
        Specified by:
