Class CloneHelper

java.lang.Object

com.yahoo.processing.request.CloneHelper

public class CloneHelper
extends Object

Helps to deep clone complex objects The following classes and their subclasses does have a fastpath - com.yahoo.component.provider.FreezableClass - com.yahoo.processing.request.properties.PublicCloneable BTW, this is the one you should implement too if you want the fastpath. - java.util.LinkedList - java.util.ArrayList The rest has the slow path with reflection, though using a fast thread safe method cache for speedup.
