类 FieldAccessBCW

java.lang.Object

org.beetl.core.om.FieldAccessBCW

所有已实现的接口:

BCW

public class FieldAccessBCW
extends Object
implements BCW

生成一个方法调用的字节码,如对User对象name属性，则生成如下代码

 public User$_name implements AttributeAccess{
        public Object value(Object o, Object name){
      return ((User)o).getName();
        }
 }
