Member Function Documentation

acknowledgmentConnect()

Smart::StatusCode SmartACE::QueryServerServiceHandler::acknowledgmentConnect ( int  cid, int  status  )

virtual

Implements SmartACE::SmartQueryClientInterface.

acknowledgmentDisconnect()

Smart::StatusCode SmartACE::QueryServerServiceHandler::acknowledgmentDisconnect ( )

virtual

Implements SmartACE::SmartQueryClientInterface.

answer()

Smart::StatusCode SmartACE::QueryServerServiceHandler::answer ( const SmartMessageBlock *  any, size_t  qid  )

virtual

Implements SmartACE::SmartQueryClientInterface.

open()

virtual int SmartACE::QueryServerServiceHandler::open ( void *  handler = 0 )

virtual

Initialization to create and activate an instance of this ACE_Svc_Handler class.

Here, memory allocation and ACE_Svc_Handler parameterization takes place. The default implementation just calls the same method from parent class.

Parameters

handler

A pointer to the parent controlling class (in this case ACE_Connector or ACE_Acceptor)

Returns

error-code

• A "-1" determines an error
• A "0" is returned if all goes right

Reimplemented from SmartACE::ServiceHandler.

serverInitiatedDisconnect()

Smart::StatusCode SmartACE::QueryServerServiceHandler::serverInitiatedDisconnect ( int  cid )

virtual

Implements SmartACE::SmartQueryClientInterface.
