io.enoa.toolkit.map

Class OKv

java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap<K,V>

java.util.LinkedHashMap<String,Object>

io.enoa.toolkit.map.OKv

All Implemented Interfaces:

FastKv<OKv>, Serializable, Cloneable, Map<String,Object>

public class OKv
extends LinkedHashMap<String,Object>
implements FastKv<OKv>

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));
