Interface ThemeResolver

All Known Implementing Classes:
AbstractThemeResolver, CookieThemeResolver, FixedThemeResolver, SessionThemeResolver

@Deprecated public interface ThemeResolver
Deprecated.
as of 6.0, with no direct replacement
Interface for web-based theme resolution strategies that allows for both theme resolution via the request and theme modification via request and response.

This interface allows for implementations based on session, cookies, etc. The default implementation is FixedThemeResolver, simply using a configured default theme.

Note that this resolver is only responsible for determining the current theme name. The Theme instance for the resolved theme name gets looked up by DispatcherServlet via the respective ThemeSource, i.e. the current WebApplicationContext.

Use RequestContext.getTheme() to retrieve the current theme in controllers or views, independent of the actual resolution strategy.
