类 CPI

java.lang.Object

com.litongjava.db.activerecord.CPI

public abstract class CPI
extends Object

Cross Package Invoking pattern for package activerecord. 为了避免开发者误用，Model、Db 中的部分方法没有完全开放出来，不能直接调用， 但可以通过 CPI 访问那些未完全开放的方法，对于扩展性开发十分有用 例如： Map attrMap = CPI.getAttrs(user); 以上代码可以获取到 User 这个 model 中的 attrs 属性
