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).

commandBuffers()

std::span< CommandBuffer *const > helios::engine::runtime::world::ResourceRegistry::commandBuffers ()

inline noexcept

Returns a read-only span of all registered CommandBuffers.

Returns

Span of CommandBuffer pointers in registration order.

Definition at line 178 of file ResourceRegistry.ixx.

178 std::span<CommandBuffer* const> commandBuffers() const noexcept {

179 return commandBufferRegistry_.items();

180 }

commandBuffers()

std::span< CommandBuffer * > helios::engine::runtime::world::ResourceRegistry::commandBuffers ()

inline noexcept

Returns a read-only span of all registered CommandBuffers.

Returns

Span of CommandBuffer pointers in registration order.

Definition at line 185 of file ResourceRegistry.ixx.

185 std::span<CommandBuffer*> commandBuffers() noexcept {

186 return commandBufferRegistry_.items();

187 }

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.

Definition at line 78 of file ResourceRegistry.ixx.

78 T& emplace(Args&&... args) {

79

80 if constexpr (IsManagerLike<T>) {

81 return managerRegistry_.template add<T>(std::forward<Args>(args)...);

82 }

83

84 if constexpr (IsCommandBufferLike<T>) {

85 return commandBufferRegistry_.template add<T>(std::forward<Args>(args)...);

86 }

87

88 assert(false);

89 }

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

T	The resource type.

Returns

Reference to the resource.

Precondition

The resource must be registered.

Definition at line 144 of file ResourceRegistry.ixx.

144 T& get() const noexcept {

145 assert(has<T>() && "Resource not found");

146 if constexpr (IsManagerLike<T>) {

147 return *managerRegistry_.item<T>();

148 }

149

150 if constexpr (IsCommandBufferLike<T>) {

151 return *commandBufferRegistry_.item<T>();

152 }

153

154 assert(false);

155 }

Reference has.

has()

template <class T>

bool helios::engine::runtime::world::ResourceRegistry::has ()

inline noexcept

Checks if a resource of type T is registered.

Template Parameters

T	The resource type.

Returns

True if the resource is registered.

Definition at line 99 of file ResourceRegistry.ixx.

99 bool has() const noexcept {

100 if constexpr (IsManagerLike<T>) {

101 return managerRegistry_.has<T>();

102 }

tryGet()

template <class T>

T * helios::engine::runtime::world::ResourceRegistry::tryGet ()

inline noexcept

Retrieves a registered resource by type.

Template Parameters

T	The resource type.

Returns

Pointer to the resource, or nullptr if not registered.
