+--com.sleepycat.bdb.collection.StoredSortedValueSet
The SortedSet returned by Map.values() and which can also be constructed directly if a Map is not needed. Although this collection is a set it may contain duplicate values. Only if an entity value binding is used are all elements guaranteed to be unique.
In addition to the standard SortedSet methods, this class provides the following methods for stored sorted value sets only. Note that the use of these methods is not compatible with the standard Java collections interface.
| Constructor Summary | |
StoredSortedValueSet(DataIndex index,
DataBinding valueBinding,
boolean writeAllowed)
Creates a sorted value set view of a DataIndex. |
|
StoredSortedValueSet(DataIndex index,
EntityBinding valueEntityBinding,
boolean writeAllowed)
Creates a sorted value set entity view of a DataIndex. |
|
StoredSortedValueSet(DataStore store,
EntityBinding valueEntityBinding,
boolean writeAllowed)
Creates a sorted value set entity view of a DataStore. |
|

SortedSet |
subSet(Object fromValue,
Object toValue)
Returns a view of the portion of this sorted set whose elements range from fromValue, inclusive, to toValue, exclusive. |
