Detailed Description

Using this strategy a single connection can have multiple outstanding requests. @ Can the performance of the demuxer be made more predictable, for example, using the request id as an active demux key?

Note:
Check the OMG resolutions about bidirectional connections, it is possible that the request ids can only assume even or odd values.

TAO_Muxed_TMS::TAO_Muxed_TMS ( TAO_Transport transport)

Constructor.

TAO_Muxed_TMS::~TAO_Muxed_TMS ( void  ) [virtual]

Destructor.

TAO_Muxed_TMS::TAO_Muxed_TMS ( const TAO_Muxed_TMS ) [private]

Member Function Documentation

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

Bind the dispatcher with the request id.

Implements TAO_Transport_Mux_Strategy.

int TAO_Muxed_TMS::clear_cache_i ( void  ) [private]
void TAO_Muxed_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_Muxed_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_Muxed_TMS::has_request ( void  ) [virtual]

Do we have a request pending.

Implements TAO_Transport_Mux_Strategy.

bool TAO_Muxed_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_Muxed_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.

void TAO_Muxed_TMS::operator= ( const TAO_Muxed_TMS ) [private]
int TAO_Muxed_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_Muxed_TMS::request_id ( void  ) [virtual]

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

Implements TAO_Transport_Mux_Strategy.

int TAO_Muxed_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.

Implements TAO_Transport_Mux_Strategy.


Member Data Documentation

Table of <Request ID, Reply Dispatcher> pairs.

Lock to protect the state of the object.

Keep track of the orb core pointer. We need to this to create the Reply Dispatchers.

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