Class 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.
