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

Database.database - is the Database underlying the new collection.keyBinding - is the binding used to translate between key buffers
and key objects.writeAllowed - is true to create a read-write collection or false
to create a read-only collection.java.lang.IllegalArgumentException - if formats are not consistently
defined or a parameter is invalid.RuntimeExceptionWrapper - if a checked exception is thrown,
including a DatabaseException on BDB (C edition).public java.util.Comparator<? super K> comparator()
Comparable interface or not.
