Class DelayedVectorProxy

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, java.lang.Iterable, java.util.Collection, java.util.List, java.util.RandomAccess, Proxy, DelayedProxy, ProxyCollection
    public class DelayedVectorProxy
extends java.util.Vector
implements ProxyCollection, DelayedProxy
    Vector proxy with delay loading capability. Allows non-indexed add and remove operations to occur on an unloaded collection. Operations that require a load will trigger a load.
