$ b& s/ [; \9 h+ p1.Create an instance of the builder object for the desired feature type providing a null object as input.
创建一个builder实例，null作为输入
2.Edit the properties of the builder object to set the feature parameters and options.
$ {; V9 S4 @! j$ U, W编辑创建的builder，设置一些参数或者选项
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.
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
