public abstract class DynAnyFactoryPOA extends Servant implements DynAnyFactoryOperations, InvokeHandler
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.

Method Detail

_invoke
public OutputStream _invoke(java.lang.String $method, InputStream in, ResponseHandler $rh)
Description copied from interface:InvokeHandler
Invoked by the ORB to dispatch a request to the servant. ORB passes the method name, an InputStream containing the marshalled arguments, and a ResponseHandler which the servant uses to construct a proper reply. Only CORBA SystemException may be thrown by this method. The method must return an OutputStream created by the ResponseHandler which contains the marshalled reply. A servant must not retain a reference to the ResponseHandler beyond the lifetime of a method invocation. Servant behaviour is defined as follows:1. Determine correct method, and unmarshal parameters from InputStream.
2. Invoke method implementation.
3. If no user exception, create a normal reply using ResponseHandler.
4. If user exception occurred, create exception reply using ResponseHandler.
5. Marshal reply into OutputStream returned by ResponseHandler.
6. Return OutputStream to ORB.
- Specified by:

- The method name.in
- TheInputStream

- TheResponseHandler
which the servant uses to construct a proper reply- Returns:
- The
