/**
 * The abstract class AbstractPropertiesKeysListResolver provides the properties key for every value
 * in the given list. Derived classes can get Properties that have a properties key prefix and
 * suffix for instance: properties key prefix='infringement.list.entry' and the properties key
 * suffix='label'. The values list contains the String object '1' and '2'. The properties file for
 * Locale.ENGLISH could look something like this: infringement.list.entry.1.label = foo
 * infringement.list.entry.2.label = bar And the properties file for Locale.GERMANY could look
 * something like this: infringement.list.entry.1.label = bla infringement.list.entry.2.label =
 * fasel And so on for other Locale objects.
 *
 * @param 
 *            the generic type of the values list
 * @deprecated use instead {@link PropertiesKeysListResolver} from project resourcebundle-core.
