public class MapAdapter<K,V>
extends AbstractMutableMap<K,V>
implements 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.
