Package org.apache.wicket.util.collections

Class MiniMap<K,V>

java.lang.Object

org.apache.wicket.util.collections.MiniMap<K,V>

Type Parameters:

K - Key type

V - Value type

All Implemented Interfaces:

Serializable, Map<K,V>

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

A fixed size map implementation. Holds an array of keys and array of values which correspond by index. Null key entries are available for use. This means that null is not a valid key.
