ConcurrentNavigableMap

public interface ConcurrentNavigableMap
implements ConcurrentMap<K, V>, NavigableMap<K, V>

java.util.concurrent.ConcurrentNavigableMap<K, V>

Known indirect subclasses

ConcurrentSkipListMap<K, V>

ConcurrentSkipListMap<K, V> A scalable concurrent ConcurrentNavigableMap implementation.

A ConcurrentMap supporting NavigableMap operations, and recursively so for its navigable sub-maps.

This interface is a member of the Java Collections Framework.

Summary

Public methods
`abstract NavigableSet<K>`	`descendingKeySet()` Returns a reverse order `NavigableSet` view of the keys contained in this map.
`abstract ConcurrentNavigableMap<K, V>`	`descendingMap()` Returns a reverse order view of the mappings contained in this map.
`abstract ConcurrentNavigableMap<K, V>`	`headMap(K toKey)` Returns a view of the portion of this map whose keys are strictly less than `toKey`. Equivalent to `headMap(toKey, false)`.
`abstract ConcurrentNavigableMap<K, V>`	`headMap(K toKey, boolean inclusive)` Returns a view of the portion of this map whose keys are less than (or equal to, if `inclusive` is true) `toKey`.
`abstract NavigableSet<K>`	`keySet()` Returns a `NavigableSet` view of the keys contained in this map.
`abstract NavigableSet<K>`	`navigableKeySet()` Returns a `NavigableSet` view of the keys contained in this map.
`abstract ConcurrentNavigableMap<K, V>`	`subMap(K fromKey, K toKey)` Returns a view of the portion of this map whose keys range from `fromKey`, inclusive, to `toKey`, exclusive. Equivalent to `subMap(fromKey, true, toKey, false)`.
`abstract ConcurrentNavigableMap<K, V>`	`subMap(K fromKey, boolean fromInclusive, K toKey, boolean toInclusive)` Returns a view of the portion of this map whose keys range from `fromKey` to `toKey`.
`abstract ConcurrentNavigableMap<K, V>`	`tailMap(K fromKey, boolean inclusive)` Returns a view of the portion of this map whose keys are greater than (or equal to, if `inclusive` is true) `fromKey`.
`abstract ConcurrentNavigableMap<K, V>`	`tailMap(K fromKey)` Returns a view of the portion of this map whose keys are greater than or equal to `fromKey`. Equivalent to `tailMap(fromKey, true)`.
