Detailed Description

Abstract base class for all Malena managers.

A Manager is responsible for driving one subsystem through the application main loop. Every concrete manager must implement the four lifecycle steps that AppManager calls each frame:

1. fireInputEvents — distribute the current SFML event to the subsystem
2. fireUpdateEvents — perform per-frame logic updates
3. run — execute any subsystem-specific per-frame work
4. draw — render the subsystem's output to the window

Managers are typically statically allocated singletons (e.g., EventsManager, ComponentsManager) rather than instances passed around by pointer, but the interface is expressed as a virtual class so that AppManager can hold a heterogeneous list of registered managers.

Member Function Documentation

draw()

virtual void ml::Manager::draw ( )

pure virtual

Render the subsystem's visual output to the window.

Called once per frame after run(). Implementations should call window.draw() on any objects this manager is responsible for drawing.

fireInputEvents()

virtual void ml::Manager::fireInputEvents ( const std::optional< sf::Event > & event )

pure virtual

Distribute an SFML input event to this subsystem.

Called once per frame for each event returned by sf::Window::pollEvent. Managers that respond to keyboard, mouse, or window events process them here.

Parameters

event

The SFML event, wrapped in std::optional. An empty optional indicates the end of the event queue (i.e., the update-only tick).

fireUpdateEvents()

virtual void ml::Manager::fireUpdateEvents ( )

pure virtual

Fire the per-frame update event across all subscribers.

Called once per frame after all input events have been processed. Use this to drive animation, polling, or any time-based logic.

run()

virtual void ml::Manager::run ( )

pure virtual

Execute subsystem-specific per-frame work.

Provides an additional hook beyond fireUpdateEvents for managers that need to perform internal bookkeeping separate from event distribution.

Implemented in ml::AppManager.
