@Retention(value=RUNTIME)
 @Target(value=TYPE)
public @interface BaseName

This annotation serves to designate the name of the resource bundle corresponding to an enum type.

Typical usage is:

 @BaseName("colors");
 @LocaleData( { @Locale("en"), @Locale("jp") } )
 public class enum Colors {
   RED, WHITE, BLUE; 
 }
 

In the above example, @BaseName("colors") means that there exists a family of resource bundle files with the base name "colors". In conjunction with the information provided in the @LocaleData annotation, we can assume that the files colors_en.properties and colors_jp.properties exist.

Verification tools such as MessageKeyVerifier can then proceed to check that the keys defined in the enum type match those in the corresponding resource bundles.
