Detailed Description

Base class for TAO_Asynch_Reply_Dispatcher and TAO_DII_Deferred_Reply_Dispatcher.

Constructor & Destructor Documentation

TAO_Asynch_Reply_Dispatcher_Base::TAO_Asynch_Reply_Dispatcher_Base ( TAO_ORB_Core orb_core,
ACE_Allocator allocator = 0 

Default constructor.

Member Function Documentation

void TAO_Asynch_Reply_Dispatcher_Base::operator= ( const TAO_Asynch_Reply_Dispatcher_Base )
virtual long TAO_Asynch_Reply_Dispatcher_Base::schedule_timer ( CORBA::ULong  ,
const ACE_Time_Value  
pure virtual

Install the timeout handler.

void TAO_Asynch_Reply_Dispatcher_Base::transport ( TAO_Transport t)

Sets the transport for this invocation.

bool TAO_Asynch_Reply_Dispatcher_Base::try_dispatch_reply ( void  )

A helper method that can be used by the subclasses.

The semantics of this helper method needs careful attention. A call to this method will do the following

  • If the reply has already been dispatched, the return value will be false to signify not to try.
  • If the reply has not been dispatched, this method will set the flag to be true and return a true value to signify that the caller thread can go ahead and dispatch reply.

Why are we clumping everything in one method. Answer is we need atomicity?

Member Data Documentation

char TAO_Asynch_Reply_Dispatcher_Base::buf_[ACE_CDR::DEFAULT_BUFSIZE]

The buffer that is used to initialise the data block.

ACE_Data_Block TAO_Asynch_Reply_Dispatcher_Base::db_

Datablock that is created on the stack to initialise the CDR stream underneath.

bool TAO_Asynch_Reply_Dispatcher_Base::is_reply_dispatched_

Has the reply been dispatched?

ACE_Lock* TAO_Asynch_Reply_Dispatcher_Base::lock_

Lock to protect is_reply_dispatched_ flag.

TAO_InputCDR TAO_Asynch_Reply_Dispatcher_Base::reply_cdr_

CDR stream which has the reply information that needs to be demarshalled by the stubs

IOP::ServiceContextList TAO_Asynch_Reply_Dispatcher_Base::reply_service_info_

The service context list.

Note, that this is not a reference as in the synchronous case. We own the reply_service_info because our TAO_Asynch_Invocation or TAO_DII_Deferred_Invocation will go out of scope before we are done.

TAO_Transport* TAO_Asynch_Reply_Dispatcher_Base::transport_

This invocation is using this transport, may change...
