13     * DynValue objects support the manipulation of IDL non-boxed value types.
14     * The DynValue interface can represent both null and non-null value types.
15     * For a DynValue representing a non-null value type, the DynValue's components comprise
16     * the public and private members of the value type, including those inherited from concrete base value types,
17     * in the order of definition. A DynValue representing a null value type has no components
18     * and a current position of -1.
19     * <P>Warning: Indiscriminantly changing the contents of private value type members can cause the value type
20     * implementation to break by violating internal constraints. Access to private members is provided to support
21     * such activities as ORB bridging and debugging and should not be used to arbitrarily violate
22     * the encapsulation of the value type.
