public class StoredSortedMap extends StoredMap implements SortedMap
In addition to the standard SortedMap methods, this class provides the following methods for stored sorted maps only. Note that the use of these methods is not compatible with the standard Java collections interface.
Constructor Summary | |
---|---|
StoredSortedMap(Database database, EntryBinding keyBinding, EntryBinding valueBinding, boolean writeAllowed)
Creates a sorted map view of a Database.
| |
StoredSortedMap(Database database, EntryBinding keyBinding, EntryBinding valueBinding, PrimaryKeyAssigner keyAssigner)
Creates a sorted map view of a Database with a PrimaryKeyAssigner. | |
StoredSortedMap(Database database, EntryBinding keyBinding, EntityBinding valueEntityBinding, boolean writeAllowed)
Creates a sorted map entity view of a Database.
| |
StoredSortedMap(Database database, EntryBinding keyBinding, EntityBinding valueEntityBinding, PrimaryKeyAssigner keyAssigner)
Creates a sorted map entity view of a Database with a PrimaryKeyAssigner. |
Method Summary | |
---|---|
Comparator | comparator()
Returns null since comparators are not supported. |
Object | firstKey()
Returns the first (lowest) key currently in this sorted map.
|
SortedMap | headMap(Object toKey)
Returns a view of the portion of this sorted set whose keys are
strictly less than toKey.
|
SortedMap | headMap(Object toKey, boolean toInclusive)
Returns a view of the portion of this sorted map whose elements are
strictly less than toKey, optionally including toKey.
|
Object | lastKey()
Returns the last (highest) element currently in this sorted map.
|
SortedMap | subMap(Object fromKey, Object toKey)
Returns a view of the portion of this sorted map whose elements range
from fromKey, inclusive, to toKey, exclusive.
|
SortedMap | subMap(Object fromKey, boolean fromInclusive, Object toKey, boolean toInclusive)
Returns a view of the portion of this sorted map whose elements are
strictly greater than fromKey and strictly less than toKey,
optionally including fromKey and toKey.
|
SortedMap | tailMap(Object fromKey)
Returns a view of the portion of this sorted map whose elements are
greater than or equal to fromKey.
|
SortedMap | tailMap(Object fromKey, boolean fromInclusive)
Returns a view of the portion of this sorted map 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. valueBinding is the binding used to translate between value buffers and value 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.
Parameters: database is the Database underlying the new collection. keyBinding is the binding used to translate between key buffers and key objects. valueBinding is the binding used to translate between value buffers and value objects. keyAssigner is used by the StoredSortedMap method to assign primary keys.
Throws: IllegalArgumentException if formats are not consistently defined or a parameter is invalid. RuntimeExceptionWrapper if a DatabaseException is thrown.
Parameters: database is the Database underlying the new collection. keyBinding is the binding used to translate between key buffers and key objects. valueEntityBinding is the binding used to translate between key/value buffers and entity value 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.
Parameters: database is the Database underlying the new collection. keyBinding is the binding used to translate between key buffers and key objects. valueEntityBinding is the binding used to translate between key/value buffers and entity value objects. keyAssigner is used by the StoredSortedMap method to assign primary keys.
Throws: IllegalArgumentException if formats are not consistently defined or a parameter is invalid. RuntimeExceptionWrapper if a DatabaseException is thrown.
Returns: null.
Returns: the first key.
Throws: RuntimeExceptionWrapper if a DatabaseException is thrown.
Note that the return value is a StoredStoredMap and must be treated as such; for example, its iterators must be explicitly closed.
Parameters: toKey is the upper bound.
Returns: the submap.
