```
boolean isPrivate()
```
    Returns true if this is a private data object with a explicit and specific set of permissions other than its parent (source).

```
boolean isSticky()
```
    Returns true if this is a sticky data object, false (or null for a default, regular data object, most likely ordered around the value or update timestamp. This is an optional flag and defaults to false if not provided explicitly.
