@Beta @GwtIncompatible(value="NavigableMap") public final class TreeRangeMap<K extends Comparable,V> extends Object implements RangeMap<K,V>
RangeMapbased on a
TreeMap, supporting all optional operations.
RangeMap implementations, this supports neither null
keys nor null values.
|Modifier and Type||Method and Description|
Returns a view of this range map as an unmodifiable
Removes all associations from this range map (optional operation).
Indicates whether some other object is "equal to" this one.
Returns the value associated with the specified key, or
Returns the range containing this key and its associated value, if such a range is present in the range map, or
Returns a hash code value for the object.
Maps a range to a specified value (optional operation).
Puts all the associations from

Returns the minimal range enclosing the ranges in this
Returns a view of the part of this range map that intersects with
Returns a string representation of the object.

Specifically, if any range in this range map contains the specified key, the value associated with that range is returned.

public Map<Range<K>,V> asMapOfRanges()
Map<Range<K>, V>. Modifications to this range map are guaranteed to read through to the returned
It is guaranteed that no empty ranges will be in the returned
For example, if
rangeMap had the entries
[1, 5] => "foo", (6, 8) => "bar", (10, ‥) => "baz"
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,

Note that it is generally necessary to override the
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.

equals(Object)method, then calling the
hashCodemethod on each of the two objects must produce the same integer result.
Object.equals(java.lang.Object)method, then calling the
hashCodemethod 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
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
JavaTM programming language.)
toStringmethod 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.
toString method for class
returns a string consisting of the name of the class of which the
object is an instance, the at-sign character `
the unsigned hexadecimal representation of the hash code of the
object. In other words, this method returns a string equal to the
getClass().getName() + '@' + Integer.toHexString(hashCode())
