## Class ScopesHashModel

- java.lang.Object
- - freemarker.template.WrappingTemplateModel
  - - freemarker.template.SimpleHash
    - - org.apache.struts2.views.freemarker.ScopesHashModel

- All Implemented Interfaces:
    freemarker.template.TemplateHashModel, freemarker.template.TemplateHashModelEx, freemarker.template.TemplateHashModelEx2, freemarker.template.TemplateModel, Serializable

      public class ScopesHashModel
      extends freemarker.template.SimpleHash
      implements freemarker.template.TemplateModel

  Simple Hash model that also searches other scopes.

  If the key doesn't exist in this hash, this template model tries to resolve the key within the attributes of the following scopes, in the order stated: Request, Session, Servlet Context

  Updated to subclass AllHttpScopesHashModel.java to incorporate invisible scopes and compatibility with freemarker.
