    Description copied from interface: RangeMap
    
    Returns a view of this range map as an unmodifiable Map<Range<K>, V>. Modifications to this range map are guaranteed to read through to the returned Map.
    The returned Map iterates over entries in ascending order of the bounds of the Range entries.
    It is guaranteed that no empty ranges will be in the returned Map.

```
public ImmutableMap<Range<K>,V> asDescendingMapOfRanges()
```
    Description copied from interface: RangeMap
    
    Returns a view of this range map as an unmodifiable Map<Range<K>, V>. Modifications to this range map are guaranteed to read through to the returned Map.
    The returned Map iterates over entries in descending order of the bounds of the Range entries.
    It is guaranteed that no empty ranges will be in the returned Map.

  - subRangeMap
```
public ImmutableRangeMap<K,V> subRangeMap(Range<K> range)
```
    Description copied from interface: RangeMap
    
    Returns a view of the part of this range map that intersects with range.
    For example, if rangeMap had the entries [1, 5] => "foo", (6, 8) => "bar", (10, ∞) => "baz" then rangeMap.subRangeMap(Range.open(3, 12)) would return a range map with the entries (3, 5] => "foo", (6, 8) => "bar", (10, 12) => "baz".
    The returned range map supports all optional operations that this range map supports, except for asMapOfRanges().iterator().remove().
    The returned range map will throw an IllegalArgumentException on an attempt to insert a range not enclosed by range.

  - hashCode
```
public 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 RangeMap<K extends Comparable<?>,V>
    
    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)
  - equals
```
public boolean equals(@Nullable Object o)
```
    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 RangeMap<K extends Comparable<?>,V>
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    o - the reference object with which to compare.
    
    Returns:
    
    true if this object is the same as the obj argument; false otherwise.

  - toString
```
public 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 RangeMap<K extends Comparable<?>,V>
    
    Overrides:
    
    toString in class Object
    
    Returns:
    
    a string representation of the object.
