```
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 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 Comparable>
  - complement
```
public ImmutableRangeSet<C> complement()
```
    Description copied from interface: RangeSet
    
    Returns a view of the complement of this RangeSet.
    The returned view supports the RangeSet.add(com.google.common.collect.Range<C>) operation if this RangeSet supports RangeSet.remove(com.google.common.collect.Range<C>), and vice versa.
    
    Specified by:
    
    complement in interface RangeSet<C extends Comparable>
  - union
```
public ImmutableRangeSet<C> union(RangeSet<C> other)
```
    Returns a new range set consisting of the union of this range set and other.
    This is essentially the same as TreeRangeSet.create(this).addAll(other) except it returns an ImmutableRangeSet.
    
    Since:
    
    21.0
  - intersection
```
public ImmutableRangeSet<C> intersection(RangeSet<C> other)
```
    Returns a new range set consisting of the intersection of this range set and other.
    This is essentially the same as TreeRangeSet.create(this).removeAll(other.complement()) except it returns an ImmutableRangeSet.
    
    Since:
    
    21.0
  - difference
```
public ImmutableRangeSet<C> difference(RangeSet<C> other)
```
    Returns a new range set consisting of the difference of this range set and other.
    This is essentially the same as TreeRangeSet.create(this).removeAll(other) except it returns an ImmutableRangeSet.
    
    Since:
    
    21.0
  - 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 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:
    
    IllegalArgumentException - if neither this range nor the domain has a lower bound, or if neither has an upper bound
  - builder
```
public static <C extends 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 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>
  - equals
```
public boolean equals(@Nullable Object obj)
```
    Description copied from class: java.lang.Object
    Indicates whether some other object is "equal to" this one.
    The equals method implements an equivalence relation on non-null object references:
    - It is reflexive: for any non-null reference value x, x.equals(x) should return true.
    - It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
    - It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
    - It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
    - For any non-null reference value x, x.equals(null) should return false.
    The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).
    Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.
    Specified by:
    
    equals in interface RangeSet<C extends Comparable>
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    obj - the reference object with which to compare.
    
    Returns:
    
    true if this object is the same as the obj argument; false otherwise.
    
    See Also:
    
    Object.hashCode(), HashMap
  - hashCode
```
public final int hashCode()
```
    Description copied from class: java.lang.Object
    Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.
    The general contract of hashCode is:
    - Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
    - If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
    - It is not required that if two objects are unequal according to the Object.equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
    As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)
    Specified by:
    
    hashCode in interface RangeSet<C extends Comparable>
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    a hash code value for this object.
    
    See Also:
    
    Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)
  - toString
```
public final String toString()
```
    Description copied from class: java.lang.Object
    Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.
    The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:
    getClass().getName() + '@' + Integer.toHexString(hashCode())
    Specified by:
    
    toString in interface RangeSet<C extends Comparable>
    
    Overrides:
    
    toString in class Object
    
    Returns:
    
    a string representation of the object.
