- * 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.

- * Creates a DynAny from a TypeCode. Depending on the TypeCode, the created object may be of type DynAny,
- * or one of its derived types, such as DynStruct. The returned reference can be narrowed to the derived type.
- * In all cases, a DynAny constructed from a TypeCode has an initial default value.
- * The default values of basic types are:
- * <UL>
- * <LI>false for boolean
- * <LI>zero for numeric types
- * <LI>zero for types octet, char, and wchar

- * <LI>a type code with a TCKind value of tk_null for type codes
- * <LI>for any values, an any containing a type code with a TCKind value of tk_null type and no value
- * </UL>
- * For complex types, creation of the corresponding DynAny assigns a default value as follows:
- * <UL>
- * <LI>For DynSequence it sets the current position to -1 and creates an empty sequence.
- * <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>
