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

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.
