        public boolean[] optionals()
        Description copied from class: BaseType
        Implementing this method allows sub-classes to specify which JSON Properties may be absent or null. When binding a JsonObject to a Java-Object, if some of the expected fields for the Java-Object map to Properties which might be left-out or omitted, then that may be indicated by setting that fields array position TRUE.

        NOTE: This array should have a length equal to the number of fields contained by the Java Object. The first boolean in the array should specify whether the first Object Field may by absent. The second boolean should specify whether the second Object Field is optional in the JSON - and so on and so forth...
        Specified by:
        optionals in class BaseType
        Returns:
        A boolean[] array whose length is precisely equal to the number of fields in the Java Object.
