java.lang.Objectcom.sleepycat.bdb.collection.MapEntry
public class MapEntry
A simple Map.Entry implementation.
Warning: Use of this interface violates the Java Collections
interface contract since these state that Map.Entry objects should only be
obtained from Map.entrySet() sets, while this class allows constructing them
directly. However, it is useful for performing operations on an entry set
such as add(), contains(), etc. For restrictions see getValue()
and
setValue(java.lang.Object)
.
