Detailed Description

Provide a standard ACE service for managing all the services configured in an ACE_Service_Repository.

This implementation is simple and just handles each client request one at a time. There are currently 3 types of requests:

Each request is associated with a new connection, which is closed when the request is processed. In addition, you must be using the singleton <ACE_Reactor::instance> in order to trigger reconfigurations.

Constructor & Destructor Documentation

ACE_Service_Manager::ACE_Service_Manager ( void  )

Constructor.

ACE_Service_Manager::~ACE_Service_Manager ( void  )
virtual

Destructor.

Member Function Documentation

void ACE_Service_Manager::dump ( void  ) const
protected

Dump the state of an object.

int ACE_Service_Manager::fini ( void  )
protectedvirtual

Terminates object when dynamic unlinking occurs.

Reimplemented from ACE_Shared_Object.

ACE_HANDLE ACE_Service_Manager::get_handle ( void  ) const
protectedvirtual

Get the I/O handle.

Reimplemented from ACE_Event_Handler.

int ACE_Service_Manager::handle_close ( ACE_HANDLE  handle,
ACE_Reactor_Mask  close_mask 
)
protectedvirtual

Called when a handle_*() method returns -1 or when the remove_handler() method is called on an ACE_Reactor. The close_mask indicates which event has triggered the handle_close() method callback on a particular handle.

Reimplemented from ACE_Event_Handler.

int ACE_Service_Manager::handle_input ( ACE_HANDLE  fd)
protectedvirtual

Called when input events occur (e.g., connection or data).

Reimplemented from ACE_Event_Handler.

int ACE_Service_Manager::handle_signal ( int  signum,
siginfo_t ,
ucontext_t  
)
protectedvirtual

Called when object is signaled by OS (either via UNIX signals or when a Win32 object becomes signaled).

Reimplemented from ACE_Event_Handler.

int ACE_Service_Manager::info ( ACE_TCHAR **  info_string,
size_t  length 
) const
protectedvirtual

Returns information on a service object.

Reimplemented from ACE_Shared_Object.

int ACE_Service_Manager::init ( int  argc,
ACE_TCHAR argv[] 
)
protectedvirtual

Initializes object when dynamic linking occurs.

Reimplemented from ACE_Shared_Object.

int ACE_Service_Manager::list_services ( void  )
protectedvirtual

Determine all the services offered by this daemon and return the information back to the client.

int ACE_Service_Manager::open ( const ACE_INET_Addr sia)
protected
void ACE_Service_Manager::process_request ( ACE_TCHAR request)
protectedvirtual

Handle one request.

int ACE_Service_Manager::reconfigure_services ( void  )
protectedvirtual

Trigger a reconfiguration of the Service Configurator by re-reading its local <svc.conf> file.

int ACE_Service_Manager::resume ( void  )
protectedvirtual

Re-enable a previously suspended service.

Reimplemented from ACE_Service_Object.

int ACE_Service_Manager::suspend ( void  )
protectedvirtual

Temporarily disable a service without removing it completely.

Reimplemented from ACE_Service_Object.

ACE_SOCK_Stream ACE_Service_Manager::client_stream_
protected

Connection to the client (we only support one client connection at a time).

bool ACE_Service_Manager::debug_
protected

Keep track whether we debug or not.

u_short ACE_Service_Manager::DEFAULT_PORT_ = 10000
staticprotected

Default port for the Acceptor to listen on.

int ACE_Service_Manager::signum_
protected

The signal used to trigger reconfiguration.
