24 * Enumeration for localized messages formats used in exceptions messages.
25 * <p>
26 * The constants in this enumeration represent the available
27 * formats as localized strings. These formats are intended to be
28 * localized using simple properties files, using the constant
29 * name as the key and the property value as the message format.
30 * The source English format is provided in the constants themselves
31 * to serve both as a reminder for developers to understand the parameters
32 * needed by each format, as a basis for translators to create
33 * localized properties files, and as a default format if some
34 * translation is missing.
