- // = TITLE
- // This class is an example of the Acceptor Pattern. This class
- // will accept new connections and create new HANDLER to handle
- // the new connections.
- //
- // = DESCRIPTION
- // Unlike the <ACE_Acceptor>, however, this class is designed to
- // be used asynchronously.
-public:
- ACE_Asynch_Acceptor (void);
- // A do nothing constructor.
-
- ~ACE_Asynch_Acceptor (void);

- size_t bytes_to_read = 0,
- int pass_addresses = 0,
- int backlog = 5,
- int reuse_addr = 1,
- ACE_Proactor *proactor = 0);
- // This starts the listening process at the port specified by
- // <address>. ACE_Asynch_Acceptor initiates the AcceptEx calls with
- // <bytes_to_read>. The buffer for the initial data will be created
- // by ACE_Asynch_Acceptor. This buffer will be passed to the
- // handler in the <ACE_Service_Handler::open> callback. If this
- // buffer is required past the <open> callback, the
- // ACE_Service_Handler must copy the data. If the <pass_addresses>
- // flag is set, ACE_Asynch_Acceptor will call
- // <ACE_Service_Handler::addresses> before calling
- // <ACE_Service_Handler::open>. The <backlog> parameter specifies
- // the listen backlog and the outstanding AcceptEx calls.
-
- int accept (size_t bytes_to_read = 0);
- // This initiates a new asynchronous accept through the AcceptEx call.
-
- static size_t address_size (void);
- // This is required by the AcceptEx call.
-
- int cancel (void);
- // This cancels all pending accepts operations that were issued by
- // the calling thread. The function does not cancel accept
- // operations issued by other threads.
-

-
- void parse_address (ACE_Message_Block &message_block,
- ACE_INET_Addr &remote_address,
- ACE_INET_Addr &local_address);
- // This parses the address from read buffer.
-
- virtual HANDLER *make_handler (void);
- // This is the template method used to create new handler.
- // Subclasses must overwrite this method if a new handler creation
- // strategy is required.
-

- ACE_HANDLE listen_handle_;
