I am a Struts2 beginner. I saw the scopedModelDriven and ScopedModelDrivenInterceptor mentioned in chapter 14 "Migration from Struts Classic" in the "Struts 2 in Action" book by "Donald Brown, ...".
The Struts2 documentation said: "public interface ScopedModelDriven<T> extends ModelDriven <https://struts.apache.org/maven/struts2-core/apidocs/com/opensymphony/xwork2/ModelDriven.html><T> Adds the ability to set a model, probably retrieved from a given state." Are scopedModelDriven and ScopedModelDrivenInterceptor used for mainly for "Migration from Struts Classic"? If not, please provide more explanation and source code examples. Thanks.
