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: + List services: If the string "help" is sent, return a list of all the services supported by the Service Configurator. + Reconfigure: If the string "reconfigure" is sent trigger a reconfiguration, which will re-read the local <svc.conf> file. + Process directive: If neither "help" nor "reconfigure" is sent, simply treat the incoming string as a process directive and pass it along to <ACE_Service_Config::process_directive>. This allows remote configuration via command-line instructions like % echo suspend My_Remote_Service | telnet hostname 3911

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.

Member Function Documentation

void ACE_Service_Manager::dump void   )  const [protected]
 

Dump the state of an object.

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

Terminates object when dynamic unlinking occurs.

Reimplemented from ACE_Shared_Object.

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_close ACE_HANDLE  fd,
ACE_Reactor_Mask

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_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.

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::init int  argc,
ACE_TCHAR argv[]
[protected, virtual]
 

Initializes object when dynamic linking occurs.

Reimplemented from ACE_Shared_Object.

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::open const ACE_INET_Addr sia  )  [protected]
 

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

Handle one request.

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::resume void   )  [protected, virtual]
 

Re-enable a previously suspended service.

Reimplemented from ACE_Service_Object.

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

Temporarily disable a service without removing it completely.

Reimplemented from ACE_Service_Object.
