/**
    * DynAny objects can be created by invoking operations on the DynAnyFactory object.
    * Generally there are only two ways to create a DynAny object:
    * <UL>
    * <LI>invoking an operation on an existing DynAny object
    * <LI>invoking an operation on a DynAnyFactory object
    * </UL>
    * A constructed DynAny object supports operations that enable the creation of new DynAny
    * objects encapsulating access to the value of some constituent.
    * DynAny objects also support the copy operation for creating new DynAny objects.
    * A reference to the DynAnyFactory object is obtained by calling ORB.resolve_initial_references()
    * with the identifier parameter set to the string constant "DynAnyFactory".
    * <P>Dynamic interpretation of an any usually involves creating a DynAny object using create_dyn_any()
    * as the first step. Depending on the type of the any, the resulting DynAny object reference can be narrowed
    * to a DynFixed, DynStruct, DynSequence, DynArray, DynUnion, DynEnum, or DynValue object reference.
    * <P>Dynamic creation of an any involves creating a DynAny object using create_dyn_any_from_type_code(),
    * passing the TypeCode associated with the value to be created. The returned reference is narrowed to one of
    * the complex types, such as DynStruct, if appropriate. Then, the value can be initialized by means of
    * invoking operations on the resulting object. Finally, the to_any operation can be invoked
    * to create an any value from the constructed DynAny.

          * <LI>For DynEnum it sets the current position to -1 and sets the value of the enumerator
          *     to the first enumerator value indicated by the TypeCode.
          * <LI>For DynFixed it sets the current position to -1 and sets the value zero.
          * <LI>For DynStruct it sets the current position to -1 for empty exceptions
          *     and to zero for all other TypeCodes. The members (if any) are (recursively) initialized
          *     to their default values.
          * <LI>For DynArray sets the current position to zero and (recursively) initializes elements
          *     to their default value.
          * <LI>For DynUnion sets the current position to zero. The discriminator value is set
          *     to a value consistent with the first named member of the union. That member is activated and (recursively)
          *     initialized to its default value.
          * <LI>For DynValue and DynValueBox it initializes to a null value.
          * </UL>
