* Trait to make enumerations serializable |

|
|
|

|
13
|
|
|
* This trait is a workaround to make enumerations serializable. |
|
14
|
|
|
* |
|
15
|
|
|
* Please note that this feature breaks singleton behaviour of your enumerations |
|
16
|
|
|
* if an enumeration will be unserialized after it was instantiated already. |
