Member Function Documentation

int ACE_POSIX_Asynch_Connect::cancel void   )  [virtual]
 

Cancel all pending pseudo-asynchronus requests Behavior as usual AIO request

Reimplemented from ACE_POSIX_Asynch_Operation.

int ACE_POSIX_Asynch_Connect::cancel_uncompleted int  flg_notify,
ACE_Handle_Set set
[private]
 

Cancel uncompleted connect operations.

  • flg_notify Indicates whether or not we should send notification about canceled accepts. If this is 0, don't send notifications about canceled connects. If 1, notify user about canceled connects according POSIX standards we should receive notifications on canceled AIO requests.

int ACE_POSIX_Asynch_Connect::close void   ) 
 

Close performs cancellation of all pending requests.

int ACE_POSIX_Asynch_Connect::connect ACE_HANDLE  connect_handle,
const ACE_Addr remote_sap,
const ACE_Addr local_sap,
int  reuse_addr,
const void *  act,
int  priority,
int  signal_number = 0
[virtual]
 

This starts off an asynchronous connect.

  • connect_handle will be used for the connect call. If ACE_INVALID_HANDLE is specified, a new handle will be created.

Implements ACE_Asynch_Connect_Impl.

ACE_HANDLE ACE_POSIX_Asynch_Connect::get_handle void   )  const [virtual]
 

virtual from ACE_Event_Handler

Reimplemented from ACE_Event_Handler.

int ACE_POSIX_Asynch_Connect::handle_close ACE_HANDLE  handle,
ACE_Reactor_Mask  close_mask
[virtual]
 

virtual from ACE_Event_Handler

Reimplemented from ACE_Event_Handler.

int ACE_POSIX_Asynch_Connect::handle_exception ACE_HANDLE  handle  )  [virtual]
 

Called when an exceptional events occur (e.g., SIGURG).

Reimplemented from ACE_Event_Handler.

int ACE_POSIX_Asynch_Connect::handle_input ACE_HANDLE  handle  )  [virtual]
 

virtual from ACE_Event_Handler Called when accept event comes up on <listen_hanlde>

Reimplemented from ACE_Event_Handler.

int ACE_POSIX_Asynch_Connect::handle_output ACE_HANDLE  handle  )  [virtual]
 

Called when output events are possible (e.g., when flow control abates or non-blocking connection completes).

Reimplemented from ACE_Event_Handler.

int ACE_POSIX_Asynch_Connect::open ACE_Handler handler,
ACE_HANDLE  handle,
const void *  completion_key,
ACE_Proactor proactor = 0
[virtual]
 

This belongs to ACE_POSIX_Asynch_Operation. We forward this call to that method. We have put this here to avoid the compiler warnings.

Reimplemented from ACE_POSIX_Asynch_Operation.

int ACE_POSIX_Asynch_Connect::post_result ACE_POSIX_Asynch_Connect_Result result,
int  flg_post
[private]
 

void ACE_POSIX_Asynch_Connect::set_handle ACE_HANDLE  handle  )  [virtual]
 

virtual from ACE_Event_Handler

Reimplemented from ACE_Event_Handler.


Member Data Documentation

int ACE_POSIX_Asynch_Connect::flg_open_ [private]
 

ACE_SYNCH_MUTEX ACE_POSIX_Asynch_Connect::lock_ [private]
 

The lock to protect the result queue which is shared. The queue is updated by main thread in the register function call and through the auxillary thread in the deregister fun. So let us mutex it.

MAP_MANAGER ACE_POSIX_Asynch_Connect::result_map_ [private]
 

Map of Result pointers that correspond to all the <accept>'s pending.

int ACE_POSIX_Asynch_Connect::task_lock_count_ [private]
 

to prevent ACE_Asynch_Pseudo_Task from deletion while we make a call to the ACE_Asynch_Pseudo_Task This is extra cost !!! we could avoid them if all applications will follow the rule: Proactor should be deleted only after deletion all AsynchOperation objects connected with it
