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

Parameters: 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.
Throws: IllegalArgumentException if formats are not consistently defined or a parameter is invalid. RuntimeExceptionWrapper if a DatabaseException is thrown.
Returns: null.
Returns: the first element.
Throws: RuntimeExceptionWrapper if a DatabaseException is thrown.
Note that the return value is a StoredCollection and must be treated as such; for example, its iterators must be explicitly closed.
Parameters: toKey is the upper bound.
Returns: the subset.
