Detailed Description

Provides static access to component pools and handles entity cleanup.

The ComponentManager is a singleton-like utility with static methods and per-type static storage (via Templates) to manage components, and versions efficiently.

Member Function Documentation

ClearRegistry()

static void FECS::Manager::ComponentManager::ClearRegistry ( )

inlinestatic

Clears all component pools and resets internal state.

Typically used in testing or to reset the ECS state.

DeleteEntity()

static void FECS::Manager::ComponentManager::DeleteEntity ( Entity e )

inlinestatic

Removes an entity from all registered component pools.

Used during entity destruction to clean up attached components.

Parameters

e	The entity to remove.

GetPool()

template<typename T>

static Container::SparseSet< T > & FECS::Manager::ComponentManager::GetPool ( EntityManager * manager )

inlinestatic

Get the component pool for a specific component type.

If the pool doesnt exist yet, it's created and registered.

Template Parameters

T	The component type.

Parameters

manager

Pointer to the EntityManager | nullptr.

Returns

Reference to the SparseSet for type T.

Note

This is a raw method to get the entity manager, its already handled via the Registry.

GetVersion()

template<typename T>

static std::uint32_t & FECS::Manager::ComponentManager::GetVersion ( )

inlinestatic

Returns a per-type version reference for tracking changes.

Used to invalidate views and other systems when component data changes.

Template Parameters

T	The component type.

Returns

Reference to a static version counter.

Reserve()

static void FECS::Manager::ComponentManager::Reserve ( std::size_t size )

inlinestatic

Reserves storage space for predicted number of component types.

Parameters

size	Number of components to reserve for

Note

This is a raw method to reserve components, its already handled via the Registry.
