|
18 | * Implementation of a property model that works off of native |
|
19 | * java enum types. |
|
20 | * |
|
21 | * <p> |
|
22 | * The enum label/values are all translated by calling Enum.toString() on your individual |
|
23 | * enum types, so it may be a good idea to provide a toString() method in your Enums if the |
|
24 | * types aren't what you would prefer to display. |
