Private Member Functions | |
Invocation_Status | check_reply_status (TAO_Synch_Reply_Dispatcher &rd) |
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.

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. |
Invocation_Status TAO::Synch_Twoway_Invocation::check_reply_status | ( | TAO_Synch_Reply_Dispatcher & | rd | ) | [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.
Invocation_Status TAO::Synch_Twoway_Invocation::handle_system_exception | ( | TAO_InputCDR & | cdr | ) | [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.
Invocation_Status TAO::Synch_Twoway_Invocation::handle_user_exception | ( | TAO_InputCDR & | cdr | ) | [protected, virtual] |
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
Invocation_Status TAO::Synch_Twoway_Invocation::location_forward | ( | TAO_InputCDR & | cdr | ) | [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.
