This annotation can be used in order to add static attributes to your data model classes. As static values should not
be changed once the parent node is online and are only synchronized to the cloud when the actual node goes online,
static attributes actually do not need to be instances of the CloudioAttribute class.
cloud.iO supports these Java types for static attributes:
- Boolean
- Integers (Short, Integer, Long)
- Numbers (Float, Double)
- String
Todo: Add example code.
