      • create

        public static <C extends java.lang.Comparable<?>> TreeRangeSet<C> create()
        Creates an empty TreeRangeSet instance.
      • create

        public static <C extends java.lang.Comparable<?>> TreeRangeSet<C> create​(RangeSet<C> rangeSet)
        Returns a TreeRangeSet initialized with the ranges in the specified range set.
      • create

        public static <C extends java.lang.Comparable<?>> TreeRangeSet<C> create​(java.lang.Iterable<Range<C>> ranges)
        Returns a TreeRangeSet representing the union of the specified ranges.

      • asRanges

        public java.util.Set<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 java.util.Set<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<?>>
      • intersects

        public boolean intersects​(Range<C> range)
        Description copied from interface: RangeSet
        Returns true if there exists a non-empty range enclosed by both a member range in this range set and the specified range. This is equivalent to calling subRangeSet(otherRange) and testing whether the resulting range set is non-empty.

        intersects in interface RangeSet<C extends java.lang.Comparable<?>>
      • encloses

        public boolean encloses​(Range<C> range)
        Description copied from interface: RangeSet
        Returns true if there exists a member range in this range set which encloses the specified range.
        Specified by:
        encloses in interface RangeSet<C extends java.lang.Comparable<?>>
      • span

        public Range<Cspan()
        Description copied from interface: RangeSet
        Returns the minimal range which encloses all ranges in this range set.
        Specified by:
        span in interface RangeSet<C extends java.lang.Comparable<?>>
      • add

        public void add​(Range<C> rangeToAdd)
        Description copied from interface: RangeSet
        Adds the specified range to this RangeSet (optional operation). That is, for equal range sets a and b, the result of a.add(range) is that a will be the minimal range set for which both a.enclosesAll(b) and a.encloses(range).

        Note that range will be coalesced with any ranges in the range set that are connected with it. Moreover, if range is empty, this is a no-op.

      • remove

        public void remove​(Range<C> rangeToRemove)
        Description copied from interface: RangeSet
        Removes the specified range from this RangeSet (optional operation). After this operation, if range.contains(c), this.contains(c) will return false.

        If range is empty, this is a no-op.

      • subRangeSet

        public RangeSet<CsubRangeSet​(Range<C> view)
        Description copied from interface: RangeSet
        Returns a view of the intersection of this RangeSet with the specified range.

        The returned view supports all optional operations supported by this RangeSet, with the caveat that an IllegalArgumentException is thrown on an attempt to add any range not enclosed by view.

      • 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>
      • isEmpty

        public boolean isEmpty()
        Description copied from interface: RangeSet
        Returns true if this range set contains no ranges.
        Specified by:
        isEmpty 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()).

        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>
      • addAll

        public void addAll​(RangeSet<C> other)
        Description copied from interface: RangeSet
        Adds all of the ranges from the specified range set to this range set (optional operation). After this operation, this range set is the minimal range set that encloses both the original range set and other.

        This is equivalent to calling RangeSet.add(com.google.common.collect.Range<C>) on each of the ranges in other in turn.

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

        Description copied from interface: RangeSet
        Removes all of the ranges from the specified range set from this range set (optional operation). After this operation, if other.contains(c), this.contains(c) will return false.

        This is equivalent to calling RangeSet.remove(com.google.common.collect.Range<C>) on each of the ranges in other in turn.

        Description copied from interface: RangeSet
        Returns true if obj is another RangeSet that contains the same ranges according to Range.equals(Object).

        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..+∞)"}.
