1.Create an instance of the builder object for the desired feature type providing a null object as input.
- J6 {$ Y7 S1 u) @创建一个builder实例，null作为输入
3 v: l. a; C( |; i& D9 Z2.Edit the properties of the builder object to set the feature parameters and options.
" o+ o7 u% Q! g; o4 M3 ?编辑创建的builder，设置一些参数或者选项
& Y+ G" q& o8 M/ n1 p" p# ?3.Use the Commit method of the builder object to create an instance of the feature.  The Commit method will return the new feature object.
0 J# d: i2 i. m0 g3 I2 c/ ~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
4.Use the Destroy method of the builder object to delete the builder object.
