Detailed Description

Manages the registration, update, and shutdown of systems.

SystemManager is a singleton that dynamically registers systems using a unique identifier. It supports both systems running in the main loop and those running on dedicated threads.

Member Function Documentation

DispatchEvent()

void Raven::SystemManager::DispatchEvent

(

Event &

e

)

Dispatches an event to all registered systems' OnEvent functions.

This method will iterate over all systems and forward the event to their respective OnEvent function, allowing systems to react to events.

Parameters

e	The event to dispatch.

operator=()

SystemManager & Raven::SystemManager::operator= ( const SystemManager & )

delete

RegisterSystem()

template<typename T, typename... Args>

void Raven::SystemManager::RegisterSystem ( bool dedicated, const std::string & id, Args &&... args )

inline

Registers a new system of type T.

Dynamically allocates the system and wraps it in a SystemHolder. The system is identified by a unique string and can optionally be run on a dedicated thread.

Template Parameters

T	The system type.
Args	Constructor argument types for the system.

Parameters

dedicated	If true, the system will run on its own thread.
id	A unique string identifier for the system.
args	Arguments forwarded to the system's constructor.

ShutdownAll()

void Raven::SystemManager::ShutdownAll

(

)

Shuts down all registered systems.

Signals each system to stop running by setting Running to false, calls the system's Shutdown function, joins dedicated threads if necessary, and destroys the system instance. Finally, clears the systems map.

ShutdownSystem()

bool Raven::SystemManager::ShutdownSystem

(

const std::string &

id

)

Shuts down a specific system identified by its unique ID.

If the system is found, it stops its execution, cleans up its resources, and removes it from the systems map.

Parameters

id	The unique identifier of the system to shut down.

Returns

true if the system was found and shut down, false otherwise.

UpdateAll()

void Raven::SystemManager::UpdateAll

(

float

ts

)

Updates all non-dedicated systems.

This function should be called from the main loop to update systems that are not running on a dedicated thread.
