| StoredSortedMap | | public class StoredSortedMap extends StoredMap implements SortedMap(Code) | | A SortedMap view of a
Database .
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.

| Method Summary | |
| public Comparator | comparator()
Returns null since comparators are not supported. | | public Object | firstKey()
Returns the first (lowest) key currently in this sorted map. | | public SortedMap | headMap(Object toKey)
Returns a view of the portion of this sorted set whose keys are
strictly less than toKey.
This method conforms to the
SortedMap.headMap interface.
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. | | public 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.
This method does not exist in the standard
SortedMap interface.
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.
Parameters:
toInclusive - is true to include toKey. | | public Object | lastKey()
Returns the last (highest) element currently in this sorted map. | | public 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.
This method conforms to the
SortedMap.subMap interface.
Note that the return value is a StoredStoredMap and must be treated
as such; for example, its iterators must be explicitly closed.
Parameters:
fromKey - is the lower bound.
Parameters:
toKey - is the upper bound. | | public 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.
This method does not exist in the standard
SortedMap interface.
Note that the return value is a StoredStoredMap and must be treated
as such; for example, its iterators must be explicitly closed.
Parameters:
fromKey - is the lower bound.
Parameters:
fromInclusive - is true to include fromKey.
Parameters:
toKey - is the upper bound.
Parameters:
toInclusive - is true to include toKey. | | public SortedMap | tailMap(Object fromKey)
Returns a view of the portion of this sorted map whose elements are
greater than or equal to fromKey.
This method conforms to the
SortedMap.tailMap interface.
Note that the return value is a StoredStoredMap and must be treated
as such; for example, its iterators must be explicitly closed.
Parameters:
fromKey - is the lower bound. | | public 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.
This method does not exist in the standard
SortedMap interface.
Note that the return value is a StoredStoredMap and must be treated
as such; for example, its iterators must be explicitly closed.
Parameters:
fromKey - is the lower bound.
Parameters:
fromInclusive - is true to include fromKey. |
