Process Lifecycle

React to the running process evolution and events.

`process::init`

Triggered when the process is started. Used primarily by modules to initialise or register features with the system.

Registering an handler

Registering a process::init handler is a special task because the registration must occur during static initialisation, a phase where the initialisation order is … fuzzy.

To help with that the sf::core::lifecycle::Process::Initialiser template can be used to register the process::init handler. In one of the component’s source files, add the following code:

using sf::core::interface::BaseLifecycleHandler;
using sf::core::interface::BaseLifecycleArg;

class MyModuleInitialiser : public BaseLifecycleHandler {
 public:
  void handle(std::string event, BaseLifecycleArg* arg) {
    // Initialisation code here ...
  }
}
LifecycleStaticOn("process::init", MyModuleInitialiser);

Keep in mind that static order initialisation is non-deterministic. As such, it is not possible to know in which order process::init handlers run!

`process::exit`

Triggered when the SnowFox process is terminated.
