## Detailed Description

Abstract base class for all the concrete implementation classes that provide different implementations for the ACE_Asynch_Operation.

## Constructor & Destructor Documentation

ACE_Asynch_Operation_Impl::~ACE_Asynch_Operation_Impl | ( | void |  | ) | `[virtual]`

ACE_INLINE ACE_Asynch_Operation_Impl::ACE_Asynch_Operation_Impl | ( | void |  | ) | `[protected]`

| Do-nothing constructor.

## Member Function Documentation

virtual int ACE_Asynch_Operation_Impl::cancel | ( | void |  | ) | `[pure virtual]`

This cancels all pending accepts operations that were issued by the calling thread. The function does not cancel asynchronous operations issued by other threads.

Implemented in ACE_POSIX_Asynch_Operation, ACE_POSIX_Asynch_Accept, ACE_POSIX_Asynch_Connect, ACE_WIN32_Asynch_Operation, ACE_WIN32_Asynch_Read_Stream, ACE_WIN32_Asynch_Write_Stream, ACE_WIN32_Asynch_Read_File, ACE_WIN32_Asynch_Write_File, ACE_WIN32_Asynch_Accept, ACE_WIN32_Asynch_Connect, ACE_WIN32_Asynch_Transmit_File, ACE_WIN32_Asynch_Read_Dgram, and ACE_WIN32_Asynch_Write_Dgram.

virtual int ACE_Asynch_Operation_Impl::open | ( | const ACE_Handler::Proxy_Ptr & | handler_proxy,
|  | ACE_HANDLE | handle,
|  | const void * | completion_key,
|  | ACE_Proactor * | proactor
| ) | `[pure virtual]`

Initializes the factory with information which will be used with each asynchronous call. If handle == ACE_INVALID_HANDLE, ACE_Handler::handle() will be called on the proxied handler to get the correct handle.

Implemented in ACE_POSIX_Asynch_Operation, ACE_POSIX_Asynch_Accept, ACE_POSIX_Asynch_Connect, ACE_WIN32_Asynch_Operation, ACE_WIN32_Asynch_Read_Stream, ACE_WIN32_Asynch_Write_Stream, ACE_WIN32_Asynch_Read_File, ACE_WIN32_Asynch_Write_File, ACE_WIN32_Asynch_Accept, ACE_WIN32_Asynch_Connect, ACE_WIN32_Asynch_Transmit_File, ACE_WIN32_Asynch_Read_Dgram, and ACE_WIN32_Asynch_Write_Dgram.

virtual ACE_Proactor* ACE_Asynch_Operation_Impl::proactor | ( | void |  | ) | const`[pure virtual]`

| Return the underlying proactor. Implemented in ACE_POSIX_Asynch_Operation, ACE_WIN32_Asynch_Operation, ACE_WIN32_Asynch_Read_Stream, ACE_WIN32_Asynch_Write_Stream, ACE_WIN32_Asynch_Read_File, ACE_WIN32_Asynch_Write_File, ACE_WIN32_Asynch_Accept, ACE_WIN32_Asynch_Connect, ACE_WIN32_Asynch_Transmit_File, ACE_WIN32_Asynch_Read_Dgram, and ACE_WIN32_Asynch_Write_Dgram.
