Classes

class  Proxy
 The Proxy class acts as a proxy for dispatch of completions to operations issued for the associated handler. It allows the handler to be deleted while operations are outstanding. The proxy must be used to get the ACE_Handler pointer for dispatching, and if it's 0, the handler is no longer valid and the result should not be dispatched. More...

Member Typedef Documentation


Constructor & Destructor Documentation

ACE_Handler::ACE_Handler ( void   ) 

A do nothing constructor.

ACE_Handler::ACE_Handler ( ACE_Proactor p  ) 

A do nothing constructor which allows proactor to be set to <p>.

ACE_Handler::~ACE_Handler ( void   )  [virtual]

Virtual destruction.

ACE_Handler::ACE_Handler ( const ACE_Handler  )  [protected]

Member Function Documentation

void ACE_Handler::handle ( ACE_HANDLE  h  )  [virtual]

Set the ACE_HANDLE value for this Handler.

Reimplemented in ACE_Asynch_Acceptor< HANDLER >.

ACE_HANDLE ACE_Handler::handle ( void   )  const [virtual]

Get the I/O handle used by this {handler}. This method will be called by the ACE_Asynch_* classes when an ACE_INVALID_HANDLE is passed to {open}.

Reimplemented in ACE_Asynch_Acceptor< HANDLER >.

void ACE_Handler::handle_accept ( const ACE_Asynch_Accept::Result result  )  [virtual]

This method will be called when an asynchronous accept completes.

Reimplemented in ACE_Asynch_Acceptor< HANDLER >.

void ACE_Handler::handle_connect ( const ACE_Asynch_Connect::Result result  )  [virtual]

This method will be called when an asynchronous connect completes.

Reimplemented in ACE_Asynch_Connector< HANDLER >.

void ACE_Handler::handle_read_dgram ( const ACE_Asynch_Read_Dgram::Result result  )  [virtual]

This method will be called when an asynchronous read completes on a UDP socket.

void ACE_Handler::handle_read_file ( const ACE_Asynch_Read_File::Result result  )  [virtual]

This method will be called when an asynchronous read completes on a file.

Reimplemented in ACE_POSIX_Asynch_Transmit_Handler.

void ACE_Handler::handle_read_stream ( const ACE_Asynch_Read_Stream::Result result  )  [virtual]

This method will be called when an asynchronous read completes on a stream.

Reimplemented in ACE_AIOCB_Notify_Pipe_Manager.

void ACE_Handler::handle_time_out ( const ACE_Time_Value tv,
const void *  act = 0 
) [virtual]

Called when timer expires. {tv} was the requested time value and {act} is the ACT passed when scheduling the timer.

void ACE_Handler::handle_transmit_file ( const ACE_Asynch_Transmit_File::Result result  )  [virtual]

This method will be called when an asynchronous transmit file completes.

void ACE_Handler::handle_wakeup ( void   )  [virtual]

This is method works with the {run_event_loop} of the ACE_Proactor. A special {Wake_Up_Completion} is used to wake up all the threads that are blocking for completions.

void ACE_Handler::handle_write_dgram ( const ACE_Asynch_Write_Dgram::Result result  )  [virtual]

This method will be called when an asynchronous write completes on a UDP socket.

void ACE_Handler::handle_write_file ( const ACE_Asynch_Write_File::Result result  )  [virtual]

This method will be called when an asynchronous write completes on a file.

void ACE_Handler::handle_write_stream ( const ACE_Asynch_Write_Stream::Result result  )  [virtual]

This method will be called when an asynchronous write completes on a stream.

Reimplemented in ACE_POSIX_Asynch_Transmit_Handler.

ACE_Handler ACE_Handler::operator= ( const ACE_Handler  )  [protected]
void ACE_Handler::proactor ( ACE_Proactor p  ) 

Set the proactor.

ACE_Proactor * ACE_Handler::proactor ( void   ) 

Get the proactor associated with this handler.

ACE_Refcounted_Auto_Ptr< ACE_Handler::Proxy, ACE_SYNCH_MUTEX > & ACE_Handler::proxy ( void   ) 

Member Data Documentation

ACE_HANDLE ACE_Handler::handle_ [protected]

The ACE_HANDLE in use with this handler.

The proactor associated with this handler.

ACE_Refcounted_Auto_Ptr<Proxy, ACE_SYNCH_MUTEX> ACE_Handler::proxy_ [protected]

Refers to proxy for this handler.
