TreeRangeMap (Guava: Google Core Libraries for Java 21.0 API)

java.lang.Object
- com.google.common.collect.TreeRangeMap<K,V>

All Implemented Interfaces:

RangeMap<K,V>
```
@Beta
 @GwtIncompatible
public final class TreeRangeMap<K extends Comparable,V>
extends Object
implements RangeMap<K,V>
```
An implementation of RangeMap based on a TreeMap, supporting all optional operations.
Like all RangeMap implementations, this supports neither null keys nor null values.

Since:

14.0

Modifier and Type	Method and Description
`Map<Range<K>,V>`	`asDescendingMapOfRanges()` Returns a view of this range map as an unmodifiable `Map<Range<K>, V>`.

`void`	`clear()` Removes all associations from this range map (optional operation).
`static <K extends Comparable,V> TreeRangeMap<K,V>`	`create()`
`boolean`	`equals(Object o)` Returns `true` if `obj` is another `RangeMap` that has an equivalent `RangeMap.asMapOfRanges()`.
`V`	`get(K key)` Returns the value associated with the specified key, or `null` if there is no such value.
`Map.Entry<Range<K>,V>`	`getEntry(K key)` Returns the range containing this key and its associated value, if such a range is present in the range map, or `null` otherwise.

  - create
```
public static <K extends Comparable,V> TreeRangeMap<K,V> create()
```
  - get
```
@Nullable
public V get(K key)
```
    Description copied from interface: RangeMap
    
    Returns the value associated with the specified key, or null if there is no such value.
    Specifically, if any range in this range map contains the specified key, the value associated with that range is returned.
    
    Specified by:
    
    get in interface RangeMap<K extends Comparable,V>
  - getEntry
```
@Nullable
public Map.Entry<Range<K>,V> getEntry(K key)
```
    Description copied from interface: RangeMap
    
    Returns the range containing this key and its associated value, if such a range is present in the range map, or null otherwise.
    
    Specified by:
    
    getEntry in interface RangeMap<K extends Comparable,V>
  - put
```
public void put(Range<K> range,
                V value)
```
    Description copied from interface: RangeMap
    
    Maps a range to a specified value (optional operation).
    Specifically, after a call to put(range, value), if range.contains(k), then get(k) will return value.
    If range is empty, then this is a no-op.
    
    Specified by:
    
    put in interface RangeMap<K extends Comparable,V>
  - putAll
```
public void putAll(RangeMap<K,V> rangeMap)
```
    Description copied from interface: RangeMap
    
    Puts all the associations from rangeMap into this range map (optional operation).
    
    Specified by:
    
    putAll in interface RangeMap<K extends Comparable,V>
  - clear
```
public void clear()
```
    Description copied from interface: RangeMap
    
    Removes all associations from this range map (optional operation).
    
    Specified by:
    
    clear in interface RangeMap<K extends Comparable,V>
  - span
```
public Range<K> span()
```
    Description copied from interface: RangeMap
    
    Returns the minimal range enclosing the ranges in this RangeMap.
    
    Specified by:
    
    span in interface RangeMap<K extends Comparable,V>
  - remove
```
public void remove(Range<K> rangeToRemove)
```
    Description copied from interface: RangeMap
    
    Removes all associations from this range map in the specified range (optional operation).
    If !range.contains(k), get(k) will return the same result before and after a call to remove(range). If range.contains(k), then after a call to remove(range), get(k) will return null.
    
    Specified by:
    
    remove in interface RangeMap<K extends Comparable,V>
  - asMapOfRanges
```
public Map<Range<K>,V> asMapOfRanges()
```
    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.
    
    Specified by:
    
    asMapOfRanges in interface RangeMap<K extends Comparable,V>
  - asDescendingMapOfRanges
```
public Map<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.
    
    Specified by:
    
    asDescendingMapOfRanges in interface RangeMap<K extends Comparable,V>
  - subRangeMap
```
public RangeMap<K,V> subRangeMap(Range<K> subRange)
```
    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.
    
    Specified by:
    
    subRangeMap in interface RangeMap<K extends Comparable,V>
  - equals
```
public boolean equals(@Nullable
                      Object o)
```
    Description copied from interface: RangeMap
    
    Returns true if obj is another RangeMap that has an equivalent RangeMap.asMapOfRanges().
    
    Specified by:
    
    equals in interface RangeMap<K extends Comparable,V>
    
    Overrides:
    
    equals in class Object
  - hashCode
```
public int hashCode()
```
    Description copied from interface: RangeMap
    
    Returns asMapOfRanges().hashCode().
    
    Specified by:
    
    hashCode in interface RangeMap<K extends Comparable,V>
    
    Overrides:
    
    hashCode in class Object
  - toString
```
public String toString()
```
    Description copied from interface: RangeMap
    
    Returns a readable string representation of this range map.
    
    Specified by:
    
    toString in interface RangeMap<K extends Comparable,V>
    
    Overrides:
    
    toString in class Object
