# w6 U- i9 E6 R3.Use the Commit method of the builder object to create an instance of the feature.  The Commit method will return the new feature object.
使用commit的方法来创建这个feature的实例，这样就可以返回一个feature对象
; c& ?' M8 [9 W9 A4.Use the Destroy method of the builder object to delete the builder object.
* Y  R& \& j5 U" y/ }使用destory方法删除builder对象。
编辑特征也是同样的操作过程！
