public class Messages
extends BundleConfigHome

An extension of configuration file handling. The configuration file consists of lines with key-value pairs (called 'messages'). In addition to simplify the reading of configuration files, this class also handles messages in different files representing the messages in different languages. When a message is not available in the localized language, the corresponding value for the default language is returned.
The default file name is messages.properties, the file name for a different language include a language code as lowercase ISO 639 code, e.g. for english, the file name would be messages_en.properties.
