Description

Unified type-indexed registry for all engine resources.

ResourceRegistry acts as the central access point for Managers and CommandBuffers. It delegates to a ManagerRegistry and a CommandBufferRegistry internally, routing registration and lookup based on compile-time concept checks (IsManagerLike / IsCommandBufferLike).

emplace()

template <class T, class... Args>

T & helios::engine::runtime::world::ResourceRegistry::emplace (Args &&... args)

inline

Registers and constructs a resource of type T.

Routes to ManagerRegistry or CommandBufferRegistry based on whether T satisfies IsManagerLike or IsCommandBufferLike. The resource is constructed in-place with forwarded arguments.

Template Parameters

T	The resource type. Must satisfy IsManagerLike or IsCommandBufferLike.
Args	Constructor argument types.

Parameters

args	Arguments forwarded to the T constructor.

Returns

Reference to the newly registered resource.

get()

template <class T>

T & helios::engine::runtime::world::ResourceRegistry::get ()

inline noexcept

Retrieves a registered resource by type (checked).

Asserts that the resource is registered before returning.

Template Parameters
