Class StandardSitePreferenceHandler

java.lang.Object

org.springframework.mobile.device.site.StandardSitePreferenceHandler

All Implemented Interfaces:

SitePreferenceHandler

public class StandardSitePreferenceHandler
extends java.lang.Object
implements SitePreferenceHandler

A helper that resolves the user's site preference and makes it available as a request attribute. Primarily used to support the case where a user on a mobile device prefers to use the normal site. The site preference may be changed on behalf of a user by submitting the 'site_preference' query parameter. The preference value is saved in a repository so it can be remembered until the user decides to change it again. If no site preference is specified, preference to the mobile site will be given if the current device is a mobile device. The current user SitePreference is exported as a request attribute with the name SitePreferenceHandler.CURRENT_SITE_PREFERENCE_ATTRIBUTE. This allows handler mappings and view resolvers further down the line to vary their logic by site preference.

Description copied from interface: SitePreferenceHandler

Handle the site preference aspect of the web request. Implementations should check if the user has indicated a site preference. If so, the indicated site preference should be saved and remembered for future requests. If no site preference has been indicated, an implementation may derive a default site preference from the Device that originated the request. After handling, the resolved site preference is available as a request attribute.

Specified by:

handleSitePreference in interface SitePreferenceHandler

Returns:

the resolved site preference for the user that originated the web request
