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

65          * In all cases, a DynAny constructed from a TypeCode has an initial default value.

67          * <UL>
68          * <LI>false for boolean
69          * <LI>zero for numeric types
70          * <LI>zero for types octet, char, and wchar

75          * </UL>
76          * For complex types, creation of the corresponding DynAny assigns a default value as follows:
77          * <UL>
78          * <LI>For DynSequence it sets the current position to -1 and creates an empty sequence.
79          * <LI>For DynEnum it sets the current position to -1 and sets the value of the enumerator
80          *     to the first enumerator value indicated by the TypeCode.
81          * <LI>For DynFixed it sets the current position to -1 and sets the value zero.
82          * <LI>For DynStruct it sets the current position to -1 for empty exceptions
83          *     and to zero for all other TypeCodes. The members (if any) are (recursively) initialized
84          *     to their default values.
85          * <LI>For DynArray sets the current position to zero and (recursively) initializes elements
86          *     to their default value.
87          * <LI>For DynUnion sets the current position to zero. The discriminator value is set
88          *     to a value consistent with the first named member of the union. That member is activated and (recursively)
89          *     initialized to its default value.
90          * <LI>For DynValue and DynValueBox it initializes to a null value.
