@Beta @GwtIncompatible(value="NavigableMap") public class ImmutableRangeMap<K extends Comparable<?>,V> extends Object implements RangeMap<K,V>
RangeMap
, supporting all query operations efficiently.
Like all RangeMap
implementations, this supports neither null keys nor null values.

ImmutableRangeMap.Builder<K extends Comparable<?>,V>
A builder for immutable range maps.
|
Modifier and Type | Method and Description |
---|---|
ImmutableMap<Range<K>,V> |
asMapOfRanges()
Returns a view of this range map as an unmodifiable
Map<Range<K>, V> . |
static <K extends Comparable<?>,V> |
builder()
Returns a new builder for an immutable range map.
|
void |
clear()
Removes all associations from this range map (optional operation).
|
static <K extends Comparable<?>,V> |
copyOf(RangeMap<K,? extends V> rangeMap) |
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() . |
static <K extends Comparable<?>,V> |
of()
Returns an empty immutable range map.
|
static <K extends Comparable<?>,V> |
of(Range<K> range,
V value)
Returns an immutable range map mapping a single range to a single value.
|
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> range)
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 . |
ImmutableRangeMap<K,V> |
subRangeMap(Range<K> range)
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.

RangeMap
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.

public void put(Range<K> range, V value)
RangeMap
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.

public void remove(Range<K> range)
RangeMap
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
.

in interface RangeMap<K extends Comparable<?>,V>
public ImmutableMap<Range<K>,V> asMapOfRanges()
RangeMap
Map<Range<K>, V>
.
Modifications to this range map are guaranteed to read through to the returned Map
.
It is guaranteed that no empty ranges will be in the returned Map
.
asMapOfRanges
in interface RangeMap<K extends Comparable<?>,V>
public ImmutableRangeMap<K,V> subRangeMap(Range<K> range)
RangeMap
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
.
