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, TAO_Reply_Dispatcher *    rd )  [virtual]

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

int TAO_Exclusive_TMS::idle_after_reply (  void    )  [virtual]

Request is sent and the reply is received. Idle the transport now. Reimplemented from TAO_Transport_Mux_Strategy.

int TAO_Exclusive_TMS::idle_after_send (  void    )  [virtual]

Request has been just sent, but the reply is not received. Idle the transport now. Reimplemented from TAO_Transport_Mux_Strategy.

CORBA::ULong TAO_Exclusive_TMS::request_id (  void    )  [virtual]

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

void 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 timedout. The strategy can (must) cleanup any resources associated with the request. A later reply for that request should be ignored. Reimplemented from TAO_Transport_Mux_Strategy.
