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.

Member Function Documentation

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.

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.

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 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

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().
