17 | * The <code>LocaleMessageHandler</code> is essentially a merging of the Message | |
18 | * and Messages classes, since there is no good reason to have them separate. A | |
19 | * key point is that this Handler is meant to be used for application-specific | |
20 | * messages, rather than core system messages. (That's not to say it couldn't | |
21 | * eventually replace the latter, however). Note that message codes are Strings | |
22 | * here, instead of the ints in Message. | |
23 | * <p/> | |
24 | * The LocaleMessageHandler can be called directly, but is really meant to be | |
25 | * called by LocaleMessage classes as done in the examples. | |
26 | * <p/> | |
27 | * Note that this class assumes the resource bundle is in the format | |
28 | * <bundle-name>-messages and is located at the top of the jar or classes | |
29 | * directory. We can later add the ability to specify a path prefix. | |
