- All Implemented Interfaces:
Streamable
public final class DynAnyFactoryHolder extends java.lang.Object implements Streamable
DynAny objects can be created by invoking operations on the DynAnyFactory object. Generally there are only two ways to create a DynAny object:- invoking an operation on an existing DynAny object
- invoking an operation on a DynAnyFactory object
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.
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.
