This class is an example of the Connector pattern. This class will establish new connections and create new HANDLER objects to handle the new connections.
Unlike the ACE_Connector, however, this class is designed to be used asynchronously with the ACE Proactor framework.

Reimplemented from ACE_Handler.

This is the template method used to create new handler. Subclasses must overwrite this method if a new handler creation strategy is required.

This parses the address from read buffer.

Set and get flag that indicates if parsing and passing of addresses to the service_handler is necessary.

virtual |
Template method to validate peer before service is opened. This method is called when the connection attempt completes, whether it succeeded or failed, if the validate_connection argument to open()
was non-zero or the validate_new_connection()
method is called to turn this feature on. The default implementation returns 0. Users can (and probably should) reimplement this method to learn about the success or failure of the connection attempt. If the connection completed successfully, this method can be used to perform validation of the peer using it's address, running an authentication procedure (such as SSL) or anything else necessary or desireable. The return value from this method determines whether or not ACE will continue opening the service or abort the connection.
result | Result of the connection acceptance. Use result.success() to determine success or failure of the connection attempt. |
remote | Peer's address. If the connection failed, this object is undefined. |
local | Local address connection was completed from. If the connection failed, this object is undefined. |
-1 | ACE_Asynch_Connector will close the connection, and the service will not be opened. |
0 | Service opening will proceeed. |
