Class DeepCloneableLinkedHashMap<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap<K,V>

java.util.LinkedHashMap<K,V>

com.bstek.dorado.util.DeepCloneableLinkedHashMap<K,V>

All Implemented Interfaces:

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

public class DeepCloneableLinkedHashMap<K,V>
extends java.util.LinkedHashMap<K,V>
implements java.lang.Cloneable

支持深度克隆的LinkedHashMap。

深度克隆是指在克隆Map时同时克隆Map中引用的每一个值对象，新的Map将会引用这些克隆后得到的新的值对象。
需要注意的是，如果原Map中引用的某个值对象不支持Cloneable接口，那么在执行克隆时将跳过对该值对象的克隆， 新的Map将直接引用原先的值对象。

DeepCloneableLinkedHashMap继承自LinkedHashMap，所以在进行键值的迭代时， 键值的迭代顺序将与之前键值被put到Map中的先后顺序保持一致。
