Class Okv

java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap<K,V>

java.util.LinkedHashMap

com.jfinal.kit.Okv

All Implemented Interfaces:

Serializable, Cloneable, Map

public class Okv
extends LinkedHashMap

Okv (Ordered Key Value) Okv 与 Kv 的唯一区别在于 Okv 继承自 LinkedHashMap，而 Kv 继承自 HashMap 所以对 Okv 中的数据进行迭代输出的次序与数据插入的先后次序一致 Example： Okv para = Okv.by("id", 123); User user = user.findFirst(getSqlPara("find", para));
