Detailed Description

ServiceManager allows you to control services installed by PackageManager.

Each std::string name given by user are processed. The best form is PackageName.ServiceName. The function checking the name throws if package or service does not exist. The other form allowed for compatibility, is ServiceName only. It is dangerous to use that because it may conflict. And you could have launch an other service. It throws if the service cannot be found in any package.

Signals Documentation

qi::Signal<std::string, qi::ServiceEventReason> qi::ServiceManager::serviceStarted

Reason is always ProcessStartRequest.

qi::Signal<std::string, qi::ServiceEventReason> qi::ServiceManager::serviceStopped

Reason can be ProcessStopRequest when the stop is regular. Or ProcessCrashed if an error occurred.

qi::Signal<std::string> qi::ServiceManager::serviceAdded

Signal sent when a new service is handled by ServiceManager.

qi::Signal<std::string> qi::ServiceManager::serviceRemoved

Signal sent when a service is removed from serviceManager.

Function Documentation

qi::ServiceManager::ServiceManager(qi::SessionPtr session)

As soon as package manager is available, launch asynchronously autorun-services.

qi::ServiceManager::ServiceManager(qi::SessionPtr session, const std::vector<std::string>& coreServices)

As soon as package manager is available, launch asynchronously autorun-services.

qi::ServiceManager::~ServiceManager()

Stop all services.

qi::Future<void> qi::ServiceManager::start(const std::string& name)

Brief: Start a service with his name.

Returns:false on error, true on success

Send signal qi::ServiceManager::serviceStarted if service is successfully launched.

qi::Future<void> qi::ServiceManager::stop(const std::string& name)

Brief: Stop service with his name.

Returns:false on error, true on success

Try to kill with sigTerm. After 15 second, kill with sigKill.

Send signal qi::ServiceManager::serviceStopped if service is successfully stopped. If service is sigTermed reason of the signal is proccessStopped, if it is sigKilled the reason is processCrashed.

qi::Future<void> qi::ServiceManager::stopAllServices()

Try to kill with sigTerm. After 15 second, kill with sigKill.

Send signal qi::ServiceManager::serviceStopped if service is successfully stopped. If service is sigTermed reason of the signal is proccessStopped, if it is sigKilled the reason is processCrashed.

qi::Future<void> qi::ServiceManager::restart(const std::string& name)

In fact, call stop and start.

If service is not already started, it is the same as qi::ServiceManager::startService.

qi::Future<bool> qi::ServiceManager::isServiceRunning(const std::string& name) const

Brief: Check that the service named name is started or not.

Returns:True if service is running, False otherwise.
std::vector<qi::ServiceProcessInfo> qi::ServiceManager::services()

Get the list of all services.

qi::ServiceProcessInfo qi::ServiceManager::service(const std::string& name)
qi::Future<size_t> qi::ServiceManager::serviceMemoryUsage(const std::string& name)
qi::Future<bool> qi::ServiceManager::startService(const std::string& name)

Send signal qi::ServiceManager::serviceStarted if service is successfully launched. DeprecatedSince 2.5.0 use ‘start’ instead false on error, true on success

qi::Future<bool> qi::ServiceManager::stopService(const std::string& name)

Brief: Stop service with his name.

Returns:false on error, true on success

Try to kill with sigTerm. After 15 second, kill with sigKill.

Send signal qi::ServiceManager::serviceStopped if service is successfully stopped. If service is sigTermed reason of the signal is proccessStopped, if it is sigKilled the reason is processCrashed. DeprecatedSince 2.5.0 use ‘stop’ instead

qi::Future<bool> qi::ServiceManager::restartService(const std::string& name)

In fact, call stop and start. DeprecatedSince 2.5.0 use ‘restart’ instead

If service is not already started, it is the same as qi::ServiceManager::startService.
