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   ) 

Destructor.


Member Function Documentation

int ACE_Service_Manager::reconfigure_services ( void   )  [protected, virtual]

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

int ACE_Service_Manager::list_services ( void   )  [protected, virtual]

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

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

Initializes object when dynamic linking occurs.

Reimplemented from ACE_Shared_Object.

int ACE_Service_Manager::info ( ACE_TCHAR **  info_string,
size_t  length 
) const [protected, virtual]

Returns information on a service object.

Reimplemented from ACE_Shared_Object.

int ACE_Service_Manager::fini ( void   )  [protected, virtual]

Terminates object when dynamic unlinking occurs.

Reimplemented from ACE_Shared_Object.

int ACE_Service_Manager::suspend ( void   )  [protected, virtual]

Temporarily disable a service without removing it completely.

Reimplemented from ACE_Service_Object.

int ACE_Service_Manager::resume ( void   )  [protected, virtual]

Re-enable a previously suspended service.

Reimplemented from ACE_Service_Object.

ACE_BEGIN_VERSIONED_NAMESPACE_DECL void ACE_Service_Manager::dump ( void   )  const [protected]

Dump the state of an object.

int ACE_Service_Manager::open ( const ACE_INET_Addr sia  )  [protected]

ACE_HANDLE ACE_Service_Manager::get_handle ( void   )  const [protected, virtual]

Get the I/O handle.

Reimplemented from ACE_Event_Handler.

int ACE_Service_Manager::handle_input ( ACE_HANDLE  fd  )  [protected, virtual]

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

Reimplemented from ACE_Event_Handler.

int ACE_Service_Manager::handle_close ( ACE_HANDLE  handle,
ACE_Reactor_Mask  close_mask 
) [protected, virtual]

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_signal ( int  signum,
siginfo_t ,
ucontext_t  
) [protected, virtual]

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

Reimplemented from ACE_Event_Handler.

void ACE_Service_Manager::process_request ( ACE_TCHAR request  )  [protected, virtual]

Handle one request.


Member Data Documentation

ACE_Service_Manager::ACE_ALLOC_HOOK_DECLARE [protected]

Declare the dynamic allocation hooks.

ACE_SOCK_Stream ACE_Service_Manager::client_stream_ [protected]

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

ACE_SOCK_Acceptor ACE_Service_Manager::acceptor_ [protected]

Acceptor instance.

bool ACE_Service_Manager::debug_ [protected]

Keep track whether we debug or not.

int ACE_Service_Manager::signum_ [protected]

The signal used to trigger reconfiguration.

u_short ACE_Service_Manager::DEFAULT_PORT_ = 10000 [static, protected]

Default port for the Acceptor to listen on.
