## 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.

## Member Function Documentation

void ACE_Handler::handle | ( | ACE_HANDLE |  | ) | `[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.

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.

ACE_Proactor* ACE_Handler::proactor_`[protected]`

| The proactor associated with this handler.

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

| Refers to proxy for this handler.
