java.lang.Objectcom.sleepycat.collections.StoredContainer
com.sleepycat.collections.StoredCollection<Map.Entry<K,V>>
com.sleepycat.collections.StoredEntrySet<K,V>
public class StoredEntrySet<K,V>
The Set returned by Map.entrySet(). This class may not be instantiated
directly. Contrary to what is stated by Map.entrySet()
this class
does support the 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.
