@Deprecated
+public static interface KeeperException.CodeDeprecated
```
+
This interface contains the original static final int constants + which have now been replaced with an enumeration in Code. Do not + reference this class directly, if necessary (legacy code) continue + to access the constants through Code. + Note: an interface is used here due to the fact that enums cannot + reference constants defined within the same enum as said constants + are considered initialized _after_ the enum itself. By using an + interface as a super type this allows the deprecated constants to + be initialized first and referenced when constructing the enums. I + didn't want to have constants declared twice. This + interface should be private, but it's declared public to enable + javadoc to include in the user API spec.
