@Beta @GwtIncompatible(value="NavigableMap") 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.
| 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>. |
Map<Range<K>,V> |
asMapOfRanges()
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> |
create() |
boolean |
equals(Object o)
|
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. |
int |
hashCode()
Returns
asMapOfRanges().hashCode(). |
void |
put(Range<K> range,
V value)
Maps a range to a specified value (optional operation).
|
void |
putAll(RangeMap<K,V> rangeMap)
Puts all the associations from
rangeMap into this range map (optional operation). |
void |
remove(Range<K> rangeToRemove)
Removes all associations from this range map in the specified range (optional operation).
|
Range<K> |
span()
Returns the minimal range enclosing the ranges in this
RangeMap. |
RangeMap<K,V> |
subRangeMap(Range<K> subRange)
Returns a view of the part of this range map that intersects with
range. |
String |
toString()
Returns a readable string representation of this range map.

public static <K extends Comparable,V> TreeRangeMap<K,V> create()
@Nullable public V get(K key)
RangeMapReturns 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.
get in interface RangeMap<K extends Comparable,V>@Nullable public Map.Entry<Range<K>,V> getEntry(K key)
RangeMapReturns the range containing this key and its associated value, if such a range is present in the range map, or null otherwise.
getEntry in interface RangeMap<K extends Comparable,V>public void put(Range<K> range, V value)
RangeMapMaps 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.
put in interface RangeMap<K extends Comparable,V>public void putAll(RangeMap<K,V> rangeMap)
RangeMapPuts all the associations from rangeMap into this range map (optional operation).
putAll in interface RangeMap<K extends Comparable,V>public void clear()
RangeMapRemoves all associations from this range map (optional operation).
clear in interface RangeMap<K extends Comparable,V>public Range<K> span()
RangeMapReturns the minimal range enclosing the ranges in this RangeMap.
span in interface RangeMap<K extends Comparable,V>public void remove(Range<K> rangeToRemove)
RangeMapRemoves 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.
remove in interface RangeMap<K extends Comparable,V>public Map<Range<K>,V> asMapOfRanges()
RangeMapReturns 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.
asMapOfRanges in interface RangeMap<K extends Comparable,V>public Map<Range<K>,V> asDescendingMapOfRanges()
RangeMapReturns 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.
asDescendingMapOfRanges in interface RangeMap<K extends Comparable,V>public RangeMap<K,V> subRangeMap(Range<K> subRange)
RangeMapReturns 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.
subRangeMap in interface RangeMap<K extends Comparable,V>public boolean equals(@Nullable Object o)
RangeMapReturns true if obj is another RangeMap that has an equivalent RangeMap.asMapOfRanges().
public int hashCode()
RangeMapReturns asMapOfRanges().hashCode().
