public class MapAdapter<K,V> extends AbstractMutableMap<K,V> implements java.io.Serializable
This class provides a MutableMap wrapper around a JDK Collections Map interface instance. All the MutableMap interface methods are supported in addition to the JDK Map interface methods.To create a new wrapper around an existing Map instance, use the
adapt(Map)
factory method.- See Also:
