public class WCombinedLocalizedStrings
extends WLocalizedStrings

A localized string resolver that bundles multiple string resolvers.

This class implements the localized strings interface and delegates WString#tr() string resolution to one or more string resolvers. You will typically use this class if you want to combine different methods of string resolution (e.g. some from files, and other strings using a database).
