void TAO_ServerRequest::is_dsi ( void  )

Set the boolean member to true.

bool TAO_ServerRequest::is_forwarded ( void  ) const

Since forward location is allowed to be nil then this is a proper method to check if the request is being forwarded.

Set the reply status.

CORBA::ULong TAO_ServerRequest::request_id ( void  )

To handle System Exceptions at the lowest level, a method returning the request_id_ is needed.

void TAO_ServerRequest::request_id ( CORBA::ULong  req)

To handle System Exceptions at the lowest level, a method returning the request_id_ is needed.

Return a reference to the "request scope" PICurrent object.

void TAO_ServerRequest::send_cached_reply ( CORBA::OctetSeq ocs)

Send cached reply. Used in scenarios where the FTORB thinks that this request is a duplicate

Append reply here....

void TAO_ServerRequest::send_no_exception_reply ( void  )

Used with reliable oneway requests.

void TAO_ServerRequest::sync_after_dispatch ( void  )

Send a sync reply if needed after _dispatch is called.

Send a sync reply if needed before _dispatch is called to avoid possible queuing first.

CORBA::Boolean TAO_ServerRequest::sync_with_server ( void  ) const

Should we return before dispatching the servant?

Friends And Related Function Documentation

friend class TAO::CSD::FW_Server_Request_Wrapper

Declare FW_Server_Request_Wrapper a friend This friendship makes the FW_Server_Request_Wrapper be able to clone the TAO_ServerRequest.

friend class TAO_AMH_Response_Handler

Declare TAO_AMH_Response_Handler a friend.

The TAO_AMH_Response_Handler class needs to copy part of the state in a TAO_ServerRequest, however, we do not want to expose that state as public members of this class, neither do we want to add modifiers to the TAO_AMH_Response_Handler class that would allow us (the TAO_ServerRequest class) to set the state.

Lucky for us, C++ is a language for adult developers, and allow us to use the evil "friend" declaration.
