public class StoredSortedKeySet extends StoredKeySet implements java.util.SortedSet
In addition to the standard SortedSet methods, this class provides the following methods for stored sorted sets only. Note that the use of these methods is not compatible with the standard Java collections interface.

StoredSortedKeySet(Database database,
EntryBinding keyBinding,
boolean writeAllowed)
Creates a sorted key set view of a
Database . |
Modifier and Type | Method and Description |
---|---|
java.util.Comparator |
comparator()
Returns null since comparators are not supported.
|
java.lang.Object |
first()
Returns the first (lowest) element currently in this sorted set.
|
java.util.SortedSet |
headSet(java.lang.Object toKey)
Returns a view of the portion of this sorted set whose elements are
strictly less than toKey.
|
java.util.SortedSet |
headSet(java.lang.Object toKey,
boolean toInclusive)
Returns a view of the portion of this sorted set whose elements are
strictly less than toKey, optionally including toKey.
|
java.lang.Object |
last()
Returns the last (highest) element currently in this sorted set.
|
java.util.SortedSet |
subSet(java.lang.Object fromKey,
boolean fromInclusive,
java.lang.Object toKey,
boolean toInclusive)
Returns a view of the portion of this sorted set whose elements are
strictly greater than fromKey and strictly less than toKey,
optionally including fromKey and toKey.
|
java.util.SortedSet |
subSet(java.lang.Object fromKey,
java.lang.Object toKey)
Returns a view of the portion of this sorted set whose elements range
from fromKey, inclusive, to toKey, exclusive.
|
java.util.SortedSet |
tailSet(java.lang.Object fromKey)
Returns a view of the portion of this sorted set whose elements are
greater than or equal to fromKey.
|
java.util.SortedSet |
tailSet(java.lang.Object fromKey,
boolean fromInclusive)
Returns a view of the portion of this sorted set whose elements are
strictly greater than fromKey, optionally including fromKey.
