      • copy

        public abstract IntSet copy()
        Create a copy of this IntSet that leaves the original unchanged.
        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.

      • mutableCopy

        public abstract IntSet mutableCopy()
        Create a copy of this IntSet that contains the same set of integers.
        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()
        Ask whether the set permits in-situ modifications using add() and remove()
        Returns:
        true if the set permits in-situ modifications

      • clear

        public abstract void clear()
        Clear the contents of the IntSet (making it an empty set)

      • size

        public abstract int size()
        Get the number of integers in the set
        Returns:
        the size of the set

      • isEmpty

        public abstract boolean isEmpty()
        Determine if the set is empty
        Returns:
        true if the set is empty, false if not

      • contains

        public abstract boolean contains​(int value)
        Determine whether a particular integer is present in the set
        Parameters:
        value - the integer under test
        Returns:
        true if value is present in the set, false if not

      • remove

        public abstract boolean remove​(int value)
        Remove an integer from the set
        Parameters:
        value - the integer to be removed
        Returns:
        true if the integer was present in the set, false if it was not present

      • add

        public abstract boolean add​(int value)
        Add an integer to the set
        Parameters:
        value - the integer to be added
        Returns:
        true if the integer was added, false if it was already present

      • iterator

        public abstract IntIterator iterator()
        Get an iterator over the values
        Returns:
        an iterator over the integers in the set

      • containsAll

        public boolean containsAll​(IntSet other)
        Test if this set is a superset of another set
        Parameters:
        other - the other set
        Returns:
        true if every item in the other set is also in this set

      • union

        public IntSet union​(IntSet other)
        Form a new set that is the union of two IntSets.
        Parameters:
        other - the second set
        Returns:
        the union of the two sets

      • intersect

        public IntSet intersect​(IntSet other)
        Form a new set that is the intersection of two IntSets.
        Parameters:
        other - the second set
        Returns:
        the intersection of the two sets

      • except

        public IntSet except​(IntSet other)
        Form a new set that is the difference of this set and another set. The result will either be an immutable object, or a newly constructed object.
        Parameters:
        other - the second set
