com.sleepycat.collections.StoredEntrySet
com.sleepycat.collections.StoredSortedEntrySet
public class StoredSortedEntrySet
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.lang.Object) and StoredCollection.addAll(java.util.Collection) methods.
The Map.Entry.setValue(java.lang.Object) method of the Map.Entry objects
that are returned by this class and its iterators behaves just as the StoredIterator.set(java.lang.Object) 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.

public Comparator comparator()
Comparable interface or not.
This method does not conform to the SortedSet.comparator()
interface.
comparator in interface SortedSetpublic Object first()
SortedSet.first() interface.
first in interface SortedSetRuntimeExceptionWrapper - if a DatabaseException is thrown.public Object last()

SortedSet.headSet(java.lang.Object) interface.
Note that the return value is a StoredCollection and must be treated as such; for example, its iterators must be explicitly closed.
