All the action for a synchronous twoway invocation happen here.
An object of this type is created by TAO::Invocation_Adapter and invokes a method on this class. The method takes care of creating and sending a request, waiting for a reply and demarshalling the reply for the client.

Profile_Transport_Resolver & | resolver, | ||
TAO_Operation_Details & | detail, | ||
bool | response_expected = true |

) |
Constructor used by TAO::Invocation_Adapter.
otarget | The original target on which this invocation was started. This is there to be passed up to its parent class. |
resolver | The profile and transport holder. |
detail | Operation details of the invocation on the target |
response_expected | Flag to indicate whether the operation encapsulated by op returns a response or not. |
|
private |
Helper method that checks the reply status of the replies and takes appropriate action. This method returns an exception when there is an error.
|
protected |
Helper method used to handle system exceptions from the remote objects.
There has been a unanimous view that this is not the right way to do things. But a need to be compliant is forcing us into this.
|
protectedvirtual |
This method is selectively made virtual, so that inherited classes can overload the user exception handling type. For example the DII needs a totally different method of user exception exception handling
|
protected |
Helper method used to handle location forwarded replies.
Invocation_Status TAO::Synch_Twoway_Invocation::remote_twoway | ( | ACE_Time_Value * | max_wait_time | ) |
Method used by the adapter to kickstart an invocation to the remote object. There is a exception declaration in this method which ensures that the exceptions propogated by the remote objects are converted a CORBA exceptions for the clients. This method does a bunch of things necessary to create and send the invocation. This method is also nerve centre for the interceptor invocation points.
void TAO::Synch_Twoway_Invocation::set_retry_state | ( | Invocation_Retry_State * | retry_state | ) |
Indicate that retry state should be tracked and controlled in the presense of exceptions.
|
protected |
As the name suggests waits for a reply from the remote ORB.
This method returns an exception when there is an error.
