## 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

ACE_BEGIN_VERSIONED_NAMESPACE_DECL 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 |
| ) | `[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_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.
