com.sleepycat.collections.StoredEntrySet<K,V>
com.sleepycat.collections.StoredSortedEntrySet<K,V>
public class StoredSortedEntrySet<K,V>
The SortedSet returned by Map.entrySet(). This class may not be
instantiated directly. Contrary to what is stated by Map.entrySet()
this class does support the StoredEntrySet.add(java.util.Map.Entry
and StoredCollection.addAll(java.util.Collection extends E>)
methods.
The Map.Entry.setValue(V)
method of the Map.Entry objects
that are returned by this class and its iterators behaves just as the StoredIterator.set(E)
method does.
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.
headSet(Map.Entry, boolean)
tailSet(Map.Entry, boolean)

SortedSet<Map.Entry<K,V>> |
subSet(Map.Entry<K,V> fromMapEntry,
Map.Entry<K,V> toMapEntry)
