ConcurrentSkipListMap<K, V>

A ConcurrentMap
supporting NavigableMap
operations,
and recursively so for its navigable sub-maps.
This interface is a member of the Java Collections Framework.

Returns a reverse order NavigableSet
view of the keys contained in this map.
The set's iterator returns the keys in descending order.
The set is backed by the map, so changes to the map are
reflected in the set, and vice-versa. The set supports element
removal, which removes the corresponding mapping from the map,
via the Iterator.remove
, Set.remove
,
removeAll
, retainAll
, and clear
operations. It does not support the add
or addAll
operations.
The view's iterator
is a "weakly consistent" iterator
that will never throw ConcurrentModificationException
,
and guarantees to traverse elements as they existed upon
construction of the iterator, and may (but is not guaranteed to)
reflect any modifications subsequent to construction.
Returns a reverse order view of the mappings contained in this map. The descending map is backed by this map, so changes to the map are reflected in the descending map, and vice-versa.
The returned map has an ordering equivalent to
Collections.reverseOrder
(comparator()).
The expression m.descendingMap().descendingMap()
returns a
view of m
essentially equivalent to m
.
Returns a view of the head of the map whose keys are smaller than (or equal to, depends on inclusive argument) endKey.
toKey | the end key |
---|---|
inclusive | true if the end key is in the returned map |
Returns a sorted map over a range of this sorted map with all keys that
are less than the specified endKey
. Changes to the returned
sorted map are reflected in this sorted map and vice versa.
Note: The returned map will not allow an insertion of a key outside the specified range.
toKey | the high boundary of the range specified. |

endKey
.Returns a NavigableSet
view of the keys contained in this map.
The set's iterator returns the keys in ascending order.

Returns a view of part of the map whose keys is from startKey to endKey.

toInclusive | true if the end key is in the returned map |
Returns a sorted map over a range of this sorted map with all keys
greater than or equal to the specified startKey
and less than the
specified endKey
. Changes to the returned sorted map are
reflected in this sorted map and vice versa.
Note: The returned map will not allow an insertion of a key outside the specified range.
fromKey | the low boundary of the range (inclusive). |
---|---|
toKey | the high boundary of the range (exclusive), |
Returns a sorted map over a range of this sorted map with all keys that
are greater than or equal to the specified startKey
. Changes to
the returned sorted map are reflected in this sorted map and vice versa.
Note: The returned map will not allow an insertion of a key outside the specified range.

.Returns a view of the tail of the map whose keys are bigger than (or equal to, depends on inclusive argument) startKey.
