public class CategoryAction
extends BaseAction

Struts action class that corresponds to the category page. Used for requests to "/Category.do".

The execute method of this class populates a category's information from the database and puts it in the request and session scopes for use by the view layer. Given a CategoryForm with its code property populated, it creates and initializes an instance of Category. It then invokes ProductProcessor.getCategoryFromCode(Category) to load the category's information from the database.

In the default implementation, in addition to all of the category's regular properties, its productListCollection is populated with just those Products falling on the current page being displayed. The paging parameter for the number of items to display comes from the "categoryPageSize" setting in the sscSetting database table. Which page to display is determined by the value of the firstRow request parameter (which is held by the incoming CategoryForm and copied to the Category object being populated).

This method puts the initialized Category object in the request and session scopes as an attribute with the name "currentCategory". A Map representing the category's custom settings and other settings is also placed in the request and session scopes as an attribute named "categorySettings".

The execute method next loads a Map of attribute-only SKUs and places it in the request as an attribute named "attributeSKUs" so they may be displayed on the product page. (Attribute-only SKUs are SKUs which are not tied to any particular product but which may still be relevant to the one of the category's products.)

Finally, three other request attributes are set from the category's data. Each of these variables is initialized with default values in BaseRequestProcessor.processPreprocess(HttpServletRequest, HttpServletResponse) and altered here with category-specific data:

An instance of CartDiscountProcessor is also instantiated and place in the request scope as an attribute named "cartDiscountProcessor", to help in the display of discounts applicable to the user.
