Class ArrayMap4<K,V>

java.lang.Object

com.db4o.collections.ArrayMap4<K,V>

All Implemented Interfaces:

Activatable, java.io.Serializable, java.lang.Cloneable, java.util.Map<K,V>

public class ArrayMap4<K,V>
extends java.lang.Object
implements java.util.Map<K,V>, java.io.Serializable, java.lang.Cloneable, Activatable

Transparent activatable Map implementation. Implements Map interface using two arrays to store keys and values.

When instantiated as a result of a query, all the internal members are NOT activated at all. When internal members are required to perform an operation, the instance transparently activates all the members.
