Detailed Description

Using this strategy only one request can be pending at a time in a connection. This improves performance because the client does not have to demux the reply, and there is less need for synchronization. On the other hand, it does not scale well when you have multiple client threads or asynchronous messaging.

Member Function Documentation

int TAO_Exclusive_TMS::bind_dispatcher	(	CORBA::ULong	request_id,
		ACE_Intrusive_Auto_Ptr< TAO_Reply_Dispatcher >	rd
	)		[virtual]

Bind the dispatcher with the request id. Commonalities in the derived class implementations is kept here.

Implements TAO_Transport_Mux_Strategy.

void TAO_Exclusive_TMS::connection_closed

(

void

)

[virtual]

The transport object has closed the connection, inform all Reply dispatchers and waiting strategies.

Implements TAO_Transport_Mux_Strategy.

int TAO_Exclusive_TMS::dispatch_reply

(

TAO_Pluggable_Reply_Params &

params

)

[virtual]

Dispatch the reply for request_id, cleanup any resources allocated for that request.

Implements TAO_Transport_Mux_Strategy.

bool TAO_Exclusive_TMS::has_request

(

void

)

[virtual]

Do we have a request pending.

Implements TAO_Transport_Mux_Strategy.

bool TAO_Exclusive_TMS::idle_after_reply

(

void

)

[virtual]

Request is sent and the reply is received. Idle the transport now. The return value indicates whether idling was successful or not.

Implements TAO_Transport_Mux_Strategy.

bool TAO_Exclusive_TMS::idle_after_send

(

void

)

[virtual]

Request has been just sent, but the reply is not received. Idle the transport now. The return value indicates whether idling was successful or not.

Implements TAO_Transport_Mux_Strategy.

int TAO_Exclusive_TMS::reply_timed_out

(

CORBA::ULong

request_id

)

[virtual]

Dispatch a reply timeout for request request_id

Implements TAO_Transport_Mux_Strategy.

CORBA::ULong TAO_Exclusive_TMS::request_id

(

void

)

[virtual]

Generate and return an unique request id for the current invocation.

Implements TAO_Transport_Mux_Strategy.

int TAO_Exclusive_TMS::unbind_dispatcher

(

CORBA::ULong

request_id

)

[virtual]

Unbind the dispatcher, the client is no longer waiting for the request, for example, because the request timed out. The strategy can (must) cleanup any resources associated with the request. A later reply for that request should be ignored.

Implements TAO_Transport_Mux_Strategy.

Member Data Documentation

ACE_Intrusive_Auto_Ptr<TAO_Reply_Dispatcher> TAO_Exclusive_TMS::rd_ [protected]

Reply Dispatcher corresponding to the request. If this is zero we don't have a reply, if it not zero we have one

CORBA::ULong TAO_Exclusive_TMS::request_id_ [protected]

Request id for the current request.

CORBA::ULong TAO_Exclusive_TMS::request_id_generator_ [protected]

Used to generate a different request_id on each call to request_id().
