public abstract class DynValueBoxHelper
extends java.lang.Object
```
DynValueBox objects support the manipulation of IDL boxed value types. The DynValueBox interface can represent both null and non-null value types. For a DynValueBox representing a non-null value type, the DynValueBox has a single component of the boxed type. A DynValueBox representing a null value type has no components and a current position of -1.
