int ACE_Stream_Tail< ACE_SYNCH_DECL >::canonical_flush ( ACE_Message_Block mb) [private]
template<ACE_SYNCH_DECL >
int ACE_Stream_Tail< ACE_SYNCH_DECL >::close ( u_long  flags = 0) [virtual]

Hook called from ACE_Thread_Exit when during thread exit and from the default implementation of module_closed(). In general, this method shouldn't be called directly by an application, particularly if the Task is running as an Active Object. Instead, a special message should be passed into the Task via the put() method defined below, and the svc() method should interpret this as a flag to shut down the Task.

Reimplemented from ACE_Task_Base.

template<ACE_SYNCH_DECL >
int ACE_Stream_Tail< ACE_SYNCH_DECL >::control ( ACE_Message_Block mb) [private]

Performs canonical flushing at the ACE_Stream tail.

template<ACE_SYNCH_DECL >
void ACE_Stream_Tail< ACE_SYNCH_DECL >::dump ( void  ) const

Dump the state of an object.

Reimplemented from ACE_Task< ACE_SYNCH_USE >.

template<ACE_SYNCH_DECL >
int ACE_Stream_Tail< ACE_SYNCH_DECL >::fini ( void  ) [virtual]

Terminates object when dynamic unlinking occurs.

Reimplemented from ACE_Shared_Object.

template<ACE_SYNCH_DECL >
int ACE_Stream_Tail< ACE_SYNCH_DECL >::info ( ACE_TCHAR **  info_string,
size_t  length 
) const [virtual]

Returns information on a service object.

Reimplemented from ACE_Shared_Object.

template<ACE_SYNCH_DECL >
int ACE_Stream_Tail< ACE_SYNCH_DECL >::init ( int  argc,
ACE_TCHAR argv[] 
) [virtual]

Initializes object when dynamic linking occurs.

Reimplemented from ACE_Shared_Object.

template<ACE_SYNCH_DECL >
int ACE_Stream_Tail< ACE_SYNCH_DECL >::open ( void *  args = 0) [virtual]

Hook called to initialize a task and prepare it for execution. args can be used to pass arbitrary information into <open>.

Reimplemented from ACE_Task_Base.

template<ACE_SYNCH_DECL >
int ACE_Stream_Tail< ACE_SYNCH_DECL >::put ( ACE_Message_Block ,
ACE_Time_Value = 0 
) [virtual]

A hook method that can be used to pass a message to a task, where it can be processed immediately or queued for subsequent processing in the svc() hook method.

Reimplemented from ACE_Task_Base.

template<ACE_SYNCH_DECL >
int ACE_Stream_Tail< ACE_SYNCH_DECL >::svc ( void  ) [virtual]

Run by a daemon thread to handle deferred processing.

Reimplemented from ACE_Task_Base.
