    • 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 Comparable>
    • rangeContaining

      @CheckForNull public abstract Range<C> rangeContaining(C value)
      Description copied from interface: RangeSet
      Returns the unique range from this range set that contains value, or null if this range set does not contain value.
      Specified by:
      rangeContaining in interface RangeSet<C extends 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 Comparable>
    • add

      public void add(Range<C> range)
      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.

      Specified by:
      add in interface RangeSet<C extends Comparable>
    • remove

      public void remove(Range<C> range)
      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.

      Specified by:
      remove in interface RangeSet<C extends 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 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 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 Comparable>
    • removeAll

      public void removeAll(RangeSet<C> other)
      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.

      Specified by:
      removeAll in interface RangeSet<C extends Comparable>
    • intersects

      public boolean intersects(Range<C> otherRange)
      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.
      Specified by:
      intersects in interface RangeSet<C extends Comparable>
    • encloses

      public abstract boolean encloses(Range<C> otherRange)
      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 Comparable>
    • equals

      public boolean equals(@CheckForNull Object obj)
      Description copied from interface: RangeSet
      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 Comparable>
      Overrides:
      equals in class Object
    • hashCode

      public final int hashCode()
      Description copied from interface: RangeSet
      Returns asRanges().hashCode().
      Specified by:
      hashCode in interface RangeSet<C extends Comparable>
      Overrides:
      hashCode in class Object
    • toString

      public final 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 Comparable>
      Overrides:
      toString in class Object
