      • asRanges

        public ImmutableSet<Range<C>> asRanges()
        Description copied from interface: RangeSet
        Returns a view of the disconnected ranges that make up this range set. The returned set may be empty. The iterators returned by its Iterable.iterator() method return the ranges in increasing order of lower bound (equivalently, of upper bound).
        Specified by:
        asRanges in interface RangeSet<C extends java.lang.Comparable>

      • asDescendingSetOfRanges

        public ImmutableSet<Range<C>> asDescendingSetOfRanges()
        Description copied from interface: RangeSet
        Returns a descending view of the disconnected ranges that make up this range set. The returned set may be empty. The iterators returned by its Iterable.iterator() method return the ranges in decreasing order of lower bound (equivalently, of upper bound).
        Specified by:
        asDescendingSetOfRanges in interface RangeSet<C extends java.lang.Comparable>

      • subRangeSet

        public ImmutableRangeSet<C> subRangeSet​(Range<C> range)
        Returns a view of the intersection of this range set with the given range.
        Specified by:
        subRangeSet in interface RangeSet<C extends java.lang.Comparable>

      • asSet

        public ImmutableSortedSet<C> asSet​(DiscreteDomain<C> domain)
        Returns an ImmutableSortedSet containing the same values in the given domain contained by this range set.

        Note: a.asSet(d).equals(b.asSet(d)) does not imply a.equals(b)! For example, a and b could be [2..4] and (1..5), or the empty ranges [3..3) and [4..4).

        Warning: Be extremely careful what you do with the asSet view of a large range set (such as ImmutableRangeSet.of(Range.greaterThan(0))). Certain operations on such a set can be performed efficiently, but others (such as Set.hashCode() or Collections.frequency(java.util.Collection<?>, java.lang.Object)) can cause major performance problems.

        The returned set's Object.toString() method returns a short-hand form of the set's contents, such as "[1..100]"}.

        Throws:
        java.lang.IllegalArgumentException - if neither this range nor the domain has a lower bound, or if neither has an upper bound

      • builder

        public static <C extends java.lang.Comparable<?>> ImmutableRangeSet.Builder<C> builder()
        Returns a new builder for an immutable range set.

      • contains

        public boolean contains​(C value)
        Description copied from interface: RangeSet
        Determines whether any of this range set's member ranges contains value.
        Specified by:
        contains in interface RangeSet<C extends java.lang.Comparable>

      • clear

        public void clear()
        Description copied from interface: RangeSet
        Removes all ranges from this RangeSet (optional operation). After this operation, this.contains(c) will return false for all c.

        This is equivalent to remove(Range.all()).

        Specified by:
        clear in interface RangeSet<C extends java.lang.Comparable>

      • enclosesAll

        public boolean enclosesAll​(RangeSet<C> other)
        Description copied from interface: RangeSet
        Returns true if for each member range in other there exists a member range in this range set which encloses it. It follows that this.contains(value) whenever other.contains(value). Returns true if other is empty.

        This is equivalent to checking if this range set RangeSet.encloses(com.google.common.collect.Range<C>) each of the ranges in other.

        Specified by:
        enclosesAll in interface RangeSet<C extends java.lang.Comparable>

        Returns true if obj is another RangeSet that contains the same ranges according to Range.equals(Object).
        Specified by:
        equals in interface RangeSet<C extends java.lang.Comparable>
        Overrides:
        equals in class java.lang.Object

        Overrides:
        hashCode in class java.lang.Object

      • toString

        public final java.lang.String toString()
        Description copied from interface: RangeSet
        Returns a readable string representation of this range set. For example, if this RangeSet consisted of Range.closed(1, 3) and Range.greaterThan(4), this might return " [1..3](4..+∞)"}.
        Specified by:
        toString in interface RangeSet<C extends java.lang.Comparable>
        Overrides:
        toString in class java.lang.Object
