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
(comparator())
.
The expression
m.descendingMap().descendingMap()
returns a
view of
m
essentially equivalent to
m
.
Returns a view of the portion of this map whose keys are less than (or
equal to, if
inclusive
is true)
toKey
. The returned
map is backed by this map, so changes in the returned map are reflected
in this map, and vice-versa. The returned map supports all optional
map operations that this map supports.
The returned map will throw an
IllegalArgumentException
on an attempt to insert a key outside its range.

toKey
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.

Returns a

The set's iterator returns the keys in ascending order.
The set is backed by the map, so changes to the map are

Returns a view of the portion of this map whose keys range from
fromKey
to
toKey
. If
fromKey
and
toKey
are equal, the returned map is empty unless
fromExclusive
and
toExclusive
are both true. The
returned map is backed by this map, so changes in the returned map are
reflected in this map, and vice-versa. The returned map supports all
optional map operations that this map supports.
The returned map will throw an
IllegalArgumentException
on an attempt to insert a key outside of its range, or to construct a
submap either of whose endpoints lie outside its range.

toKey
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.
Equivalent to

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.
Equivalent to
