Class MapWrapper<K,V>

java.lang.Object
  com.gargoylesoftware.htmlunit.util.MapWrapper<K,V>

Type Parameters:

K - the type of the map key

V - the type of the value

All Implemented Interfaces:

Serializable, Map<K,V>

public class MapWrapper<K,V>
extends Object
implements Map<K,V>, Serializable

Map implementation delegating all calls to the wrapped Map instance. This class is Serializable, but serialization will fail if the wrapped map is not itself Serializable.
