Class DBObject

java.lang.Object

sf.core.DBObject

All Implemented Interfaces:

Serializable, AutoCloseable, IAssignValue, IDML, IEntity

Direct Known Subclasses:

AllowDataInitialize, VarObject

public abstract class DBObject
extends Object
implements IEntity

抽象类，用于实现所有Entity默认的各种方法
为了避免jackson,fastjson,gson出现不该序列化的字段,需要避免get,set,is等方法出现.
